To provide convenient cost-effective solutions for electrical distribution applications where a switched neutral is needed, Moeller Electric has expanded its popular and versatile range of xStart contactors to include new four-pole models. The new DILMP models cover AC1 current ratings from 22A to 200A in just four frame sizes, the new four-pole contactors feature identical dimensions for AC- and DC-operated versions, thereby simplifying panel design and construction.

Ideal for use in mains/standby changeover, heating control, and distribution systems for IT installations, xStart four-pole contactors, like their three pole counterparts, have specially designed low consumption coil assemblies.

Not only do these innovative coil systems reduce heating in the control panel and energy consumption, they also make it possible for contactors up to 45A to be controlled directly from inexpensive low current PLC outputs, thereby eliminating the need for inconvenient interposing relays or costly high-power output modules.

The use of the contactors with PLCs is further simplified by the integrated suppressor which is included as standard in all DC-operated versions.

The new contactors feature space-saving compact construction, are designed to make wiring fast and easy. Access to the coil terminals is at front-plate level and, for additional convenience and safety, double-chamber screw-clamp terminals are used throughout.

Moeller Electric offers a wide range of accessories for use with its new four-pole xStart contactors. These include mechanical interlocks for vertical and horizontal configurations, which need no additional space to be allowed between the contactors; auxiliary contacts in standard and early-make/late-break versions; suppressors for AC-operated types; and insulating shrouds.

To maximise user convenience, the new four-pole contactors use the same accessories as three-pole models in the xStart range.

Manufactured to the highest standards, xStart contactors are designed to provide maintenance-free operation for a mechanical life of at least 10 million operations. They comply with all relevant sections of IEC60947, as well as with appropriate UL and CSA requirements. In addition, they carry the CE marking.

Crydom Solid State Relays (SSRs) are utilized in numerous medical applications. Crydom SSRs are used to control motors in hospital beds, examination tables, and rehabilitation equipment. SSR’s are also widely used for heating controls in sterilization equipment, blood warming units, and incubators.

Since Crydom SSRs utilize silicon for switching loads and therefore have no contacts that arc, contact contamination and the danger of sparking are eliminated. Coupled with an epoxy-filled encapsulation, the Crydom SSR is resistant to steam and other sterilization techniques.

The recent introduction of the Crydom MC series of SSR/controllers is an all in one solution that includes both a controller and a Crydom SSR in one package to control temperature, phase control, or soft start, soft stop functions.

Schurter has created the latest addition to the existing snap-in front panel mount circuit breaker. The popular fuse holder style, single pole thermal circuit breaker series T9 is now also available with threaded-neck and snap-in versions for rear mounting. The threaded-neck type is available with an IP 65 rated cover, which provides protection against environmental conditions such as dust or jetting water. Its tripping operation is cycling trip-free.

Circuit breakers with the fuse holder style body are ideal substitutes for panel fuses where inrush currents cause nuisance trips, or aging of the fusing element overtime. Resetting the circuit can avoid unnecessary downtime and maintenance costs associated with replacing fuses. Improper replacement with the wrong current rating is also prevented. The circuit breaker button extends to indicate when the circuit is interrupted. The button returns to depressed status when pushed-to-reset.

Typical applications include power supplies, UPS, PDUs, power tools, industrial appliances, medical diagnostic and analysis appliances, lighting, sports and hobby machinery or HVAC. The T9 series meets UL standard 1077 for Supplementary Protection, CSA C22.2 235, IEC 60934 and GB 17701. Current ratings range from 4 - 16 Amps at 240 Volts AC and 48/32 Volts DC.

Finder has announced the launch of the 97.11 and 97.12 sockets for PCB mounting of its 46 series miniature industrial relays. These sockets allow engineers designing power control equipment to mount a plug-in power relay with robust terminals in a simple manner onto a PCB. They are particularly suitable for circuit boards where the ability to change power relays quickly is essential for maintenance and the minimising of downtime in the event of a fault.

There is a growing trend towards the use of PCBs in power control applications, but engineers wish to maintain the benefit of rapid component replacement that they enjoy with traditional plug-in rail mounted components – this is the need addressed by these new additions to the 97 Series of sockets.

The 97.11 and 97.12 sockets have a small 12.4mm x 32mm footprint, minimising board space requirements, and maintain the full 6kV coil-to-contact isolation specification of the relay. An integral retaining clip ensures that the relay is firmly retained when used in applications where they may be subject to shock or vibration, and the sockets carry C UR approval for the US.

The 46 Series relays, which fit the sockets, includes both single-pole and two-pole contact configurations for use in control panels and systems. The relays are fully terminal-compatible with the de-facto industry standard, with Faston spade/blade terminals that provide secure and reliable connections between the relay and the 97 Series socket.

The new sockets complete the line up of 46 series relay mounting options that already include a range of 35mm rail mounting sockets – the 97.01 and 97.02 screw connection models and the 97.51 and 97.52 screwless connection versions – as well as flange-mounting and direct-rail mounting adaptors that allow the use of either Faston or soldered connection to the relay terminals. All the 97 Series rail mounting sockets will accept the full range of 99.02 coil indication and suppression modules and the 86.30 bi-function, multi-range timer modules.

October 25, 2007 - Crydom, an operation of Custom Sensors & Technologies (CST), announces the first solid state relays available on the market with UL approved short-circuit current ratings (SCCR). These relays facilitate industrial control panel builders' efforts to comply with the new article 409 from NEC and the latest version of UL508A, both request SCCR marking, by providing them with pre-approved ratings for SSR/fuse combination.

According to Dr. Oscar Montero, from the Crydom Global Technical Center, "Standard 5kA SCCR on power devices prevents panel builders from offering panels with higher ratings. Panels with a higher SCCR could be connected to electrical systems with different available currents bringing market advantages for panel builders. However, establishing a higher SCCR may represent significant challenges and additional costs for panel builders."

Crydom's approved ratings allow panel builders to establish the SCCR for the branch circuit where the relay is located without performing additional testing. The ratings can be added directly to the manufacturer's procedure. Hence, effectively reducing the time-to-market cycle for the panel and cost associated to compliance.

Crydom has obtained UL approval for SCCR by testing the combination SSR/Fuse under the "umbrella fuse" requirement allowing more flexibility to Crydom customers to mix and match SSR and fuses of different ratings.
