ABB has launched a range of miniature circuit breakers (MCBs) aimed at OEMs, panelbuilders and the industrial sector. The System pro M compact® incorporates a number of new features designed to eliminate wiring connection errors.

A key feature is the positioning of the cabling terminal in front of the busbar connection terminal, making both terminals easier to access and see. By placing both terminal ports at the bottom of the MCB, connections can be made secure by using only one screw to fasten both the busbar connection and the electrical cabling into their respective terminals.

ABB has also introduced auxiliary contacts for the pro M compact® range, which can be added to the bottom of an MCB instead of the side. Saving up to 50% space in enclosures, this feature increases the number of auxiliary contacts which can be installed, expanding the number of remote monitoring options. Plug-in connectivity also makes the contacts simple to connect.

The pro M compact® MCBs also offer a reduced height compared to ABB’s previous range, saving around 2cm of space per MCB. This provides additional installation space for when space is at a premium.

ABB’s patented release system enables easy removal without the need for a screwdriver. Release connectors on the back of the devices allow them to be simply disconnected from the busbar after turning power off and disconnecting the wiring.

The pro M compact® range is suitable for use worldwide as the materials used to manufacture them exceed standards for both European regulations for RoHs and UL, the US directive for electrical components. The pro M compact® MCBs can be ordered ready for installation for both Europe and the US. A Europe-only version is also available.

Finder has announced an update to its 56 series relays, which now provide enhanced functionality during installation and test.

The updated series of 2-pole and 4-pole power relays feature as standard on all models a test button and mechanical indicator for manual operation during test and commissioning. The full range now offers as options an indicator LED to show operational status; in particular the DC coil versions feature twin LEDs, making them insensitive to polarity. All of the models feature a new printed front plate showing the full part number, contact rating and coil voltage, and both the new pushbutton and the coil housing are colour-coded for rapid visual identification of AC or DC models.

The six models in the 56 series provide the capability of switching higher current loads with the option of up to four changeover contacts. They are typically used by OEMs, panel builders and end users in applications including the switching of single phase motors, solenoid operation with feedback monitoring signals, multi-element heating loads and various types of lighting. The provision of plug-in, PCB and an extended range of rail and flange-mounting options and adaptors, along with a complementary range of sockets, suppression modules and accessories, allows maximum flexibility of both mounting and connection.

Standard contact material is cadmium-free, but alternative contact materials are on offer to suit inductive or capacitive loads.

The relays are rated as standard at up to 12A at 250V AC with maximum peak values of 20A and 400V AC. A 400V AC coil version is also available for use in industrial applications where a neutral connection is not available.

New to the Finder range of energy consumption meters is the three-phase 7E.36 Series, which includes single and dual-tariff kWh models for the measurement, recording and display of power consumption in individual sub-circuits at current levels up to 65A.

The meters are particularly applicable where there is a statutory need for compliance with the EU Measuring Instrument Directive (MID) 2004/22/EG which comes into force in October 2006. The current pressure to reduce energy consumption is also driving the need for accurate monitoring and measurement in specific areas.

The 7E.36 Series meters provide a compact, accurate and easily-installed solution to metering three-phase energy consumption, and are ideally suited for use by manufacturers and installers of machinery and equipment, control systems manufacturers, contractors, site service engineers and designers of building management systems (BMS). Typical areas of use include industrial and commercial installations, test cells, machines, control cabinets and switchboards.

Type 7E.36.8.400.0000 is a single-tariff 3-phase meter, and Type 7E.36.8.400.0002 is a dual-tariff version for use with standard and economy tariff supplies. Both meters are specified for a maximum current rating of 65A, and are housed in a compact 70mm wide enclosure that can be surface mounted or fitted to a 35mm DIN rail, allowing them to be installed in confined spaces or mounted on standard sub distribution boards.

The meters feature 4mm high, 7-digit display(s) including a red decimal digit, to provide an easy-to-read display with a maximum totalising count of 999,999.9kWh. A high resolution pulsed open-collector output to DIN 43864 provides a link to BMS or other types of remote monitoring system. A variable rate pulsed red LED indicator offers a rapid visual indication when abnormal operation is occurring, for example due to phase loss or inversion. Terminal covers are also available to enable a tamper-proof seal to be fitted.

The 7E.36 Series is compliant with EN 62053-21 and prEN 50470 as well as with the EU MID 2004/22/EG, and is certified by PTB (Physikalisch-Technischen Bundesanstalt). Accuracy is specified to Class B and protection to Class II.

The 4C Series is a new series of single-pole and two-pole relay interface modules from Finder that incorporate Finder’s flagship 46 Series miniature industrial relays, and are available in either screw terminal or screwless socket types. The modules provide an ideal interface between programmable logic controllers (PLC) or other electronic controllers and external actuators or switching devices, where outputs are required to switch higher than normal external loads such as large contactors, solenoids, small motors or heating elements.

The 4C.01 and 4C.02 are respectively a single-pole 16A and a two-pole 8A relay interface module, both with screw terminal connections, while the 4C.51 is a screwless single-pole model rated as 10A and the 4C.52 is an 8A two-pole screwless version. All four models are available with either AC or DC coils, and can be mounted on a 35mm DIN rail (EN 50022). They feature instant ejection of the relay from the socket by means of a plastic retaining clip, and include as standard both a supply status indication and coil suppression module.

An 8-way jumper link is available as an optional extra for use with the 4C.01 and 4C.02 modules, and reduces the time taken to wire common connections.

The 4C.01 and 4C.02 screw-type terminal modules both measure 82.9mm long x 64.6mm high x 15.8 mm wide, while the screwless 4C.51 and 4C.52 versions both measure 95.6mm long x 61.7 mm high x 15.8 mm wide. The cadmium-free relay contacts are fabricated from silver nickel (AgNi) material.

Finder introduces the 72.31 three-phase monitoring relay, which is used for detecting a loss of phase or incorrect phase rotation when using three-phase supplies. This compact relay is ideally suited for the protection of motors in plant and machinery, and helps to satisfy the mandatory requirement of ensuring the correct rotation of motors in transportable equipment.

The 72.31 allows OEMs, panel builders and installers of control systems to ensure that motors do not become permanently damaged due to phase loss, and also to avoid potential hazards or damage due to incorrect rotation of the motors. The relay features positive safety logic, which triggers the contact to open if an error is detected so that the system will fail to a safe condition. The wide supply voltage specification allows a single unit to be used across the full three-phase supply voltage range of 208V to 480V AC.

The relay provides reliable monitoring of phase loss, even under conditions where the lost phase may be “regenerated” by the action of the rotating motor. This phenomenon is not uncommon, and many monitoring relay units that are currently available may falsely detect this phase regeneration and thus fail to disconnect the supply, which can cause damage to the motor. The 72.31 can discriminate phase regeneration up to 80% of the line voltage.

Featuring a SPDT output contact rated at 6A (maximum peak 15A), the 72.31 monitoring relay is enclosed in a compact housing measuring 84mm high x 56.5mm deep x 17.5mm wide. The narrow profile offers considerable saving in panel space.
