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.

ABB has extended its compact range of switches as part of its on-going replacement program for the OETL and OESA ranges. Up to 48% smaller in size, the OS and OT switches are ideal for applications where time, cost and space are at a premium.

ABB's OT switch disconnectors and OS fuse switch-disconnectors can be used as the main switch in low voltage switchgear for power distribution, starting and stopping of motors and isolating loads during maintenance. Available in metal or plastic enclosures, they can be used as safety switches to prevent accidental starting of machines. As further protection, the external operating handles have been double-insulated, which eliminates the chance of touching live parts. The fuse covers also cannot be opened when the switch fuse is on.

The reduced size of both OT and OS switches means that almost double the number of panels can be fitted onto a board that is approximately 1.3m x 2.3m, compared to their OETL and OESA range equivalents. This is ideal for installations where space is limited or at a premium.

Both OT and OS switches can be installed vertically or horizontally, enabling users to position them according to the location of the incoming supply. They are fully rated for both enclosed and open environments, negating the need for extra space if the switches are being used in an enclosure.

The OT range is available from 16A up to 800A. The OS range provides coverage from 16A, up to 400A, with the OESA continuing to provide up to 800A.

Both the OT and OS switches feature a mechanically-based design, with metal parts and double brake switching as standard. These features help to prolong the operational life of the products compared to units from other manufacturers which typically use plastic and ceramic parts. It also increases safety by providing double isolation from live parts. Further safety is provided by arc-chutes, which prevent current sparks and flashovers.

The OT range is IP20 protected, providing extensive protection against impacts from small objects such as debris being expelled by a nearby machine. It also has a patented operator independent quick-make / quick-break mechanism, providing better responsiveness and reliability when in use.

With the neutral wrapped around the main switch mechanism combining to make one unit, the OT and OS switches save space, as opposed to separate space being required for the neutral connection outside of the switch.

Two-pole or one pole versions of the switches can be produced on request. The OT and OS ranges are modular in design, providing increased flexibility on installation. Adjustable mounting feet allow the feet to be fitted at 45 or 90 degree angles.

The switches are suitable for a number of applications, ranging from motor control centres to acting as a main switch in machine applications. OT and OS switches are commonly used by water authorities, transport rail networks and in offshore applications.

ABB have also introduced change-over switches to their OT range. Available from 160A up to 800A, the change-over switches are two switches in one, and increase the ways in which the switches can be applied. It also reduces the need for separate change-over mechanisms.

ABB has released a new family of terminal blocks that dramatically reduce installation times without compromising safety. Based on ABB's insulation displacement connection (IDC) technology, the new ADO system terminal blocks can reduce wiring times by up to 80% compared with conventional terminal blocks.

The system eliminates the most common risks associated with connections, such as forgetting to strip the wire, folding over of wire strands, stripping too much wire, incorrect tightening torque or badly inserted terminal ends.

The ADO system uses a hand-operated tool to enable the operator to execute simple and accurate high-speed wiring and cutting. By ensuring a tight connection every time, ADO terminal blocks eliminate the problem of loose screw terminations, maximising safety in heavy industrial applications subject to vibration and shocks and reducing subsequent maintenance time and cost.

When a connection is made, the tool strips away the wire insulation and pushes the non-prepared conductor cable into a cutting jaw, which holds it tight and ensures a sound electrical contact. The manual tool has been specially designed for on-site maintenance and can remain permanently inside a panel. A semi-automatic version is also available, which enables repeated connections to be made quickly with minimum effort from the installer.

For wiring flexibility, users can choose ADO system blocks with an IDC termination on both sides or with a combination of IDC and screw clamp terminations.

Another key benefit of ABB's ADO system blocks is their reduced size. Up to 50 terminals can be installed per foot of DIN rail, helping to reduce the overall installation space compared to conventional terminal blocks. Further space savings are also achieved by the terminal's ability to accept two similar wires into each termination. The ADO system terminal blocks are available as standard mounted on DIN3 rail.

A 'mini' version is also available for installations with severe size constraints. Up to 25% smaller than the standard IDC blocks, the 'mini' blocks are ideal for reduced space environments. For mounting, mini block models are offered for DIN 2 or DIN 3 rails. Other models can be screwed or snapped directly onto a metal chassis, such as a panel mount. For wiring flexibility, mini IDC blocks are available with insulation displacement on one side and a standard screw clamp on the other. The 6-mm wide block is rated 18 A, the 8-mm wide block 25 A.

All ADO system blocks are UL recognized, CSA certified, 600 V up to 25 A, and meet IEC and VDE standards. In addition to the ADO system blocks, ABB also offers terminal blocks with screw clamp and spring connections.

ABB also offers an ATEX certified terminal block range for safe use in explosive atmospheres. The range is certified to the highest possible level of the ATEX directive 94/9/EC European directive.
