Save Time and Costs with Eaton DC-Contactors

Clever Use of a Proven Technology
Thanks to the use of proven hybrid technology, the contacts in Eaton DC contactors have a long lifespan and low contact wear. Hybrid contactors feature two mechanical contacts – a extinguishing contact and a break contact – that are connected in series.

Moreover, they have an IGBT power semiconductor switch connected in parallel with the extinguishing contact. When one of these contactors is switched off, the first thing that happens is that the IGBT is switched on. After this, the extinguishing contact opens mechanically, commutating the current to the IGBT so that it can be interrupted by the power electronics. Finally, the break contact is opened in a de-energized state, achieving the required potential isolation.

Together with this configuration, a wide-range coil for DC and AC voltages makes our DC contactors a maintenance-free and reliable part of any machine or system.

With a long history of innovation in the connector and EMC marketplace, Schurter expands its range of power entry modules with the introduction of the FMAD and FMAB CEE Connectors, featuring a first of its kind integrated line filter for 1- and 3-Phase industrial and power distribution applications. The integrated filter optimizes suppression of conducted emissions by eliminating cables between the inlet and filter.

The CEE connectors according IEC 60309 are used all over the world for industrial applications and power distribution. The single and three phase connectors can be used for any application with a detachable power cord. Today, noise generating electronics used in machines drive demand for EMI
suppression filters in order to meet international EMC standards. This filter is typically mounted on the metal chassis for optimal performance.

Traditionally, wires are used to connect the power inlet to the EMI filter mounted separately on the chassis. These wires can vary in length and can cause EMC problems with electromagnetic fields generated by a noise source inside the equipment bypassing the filter! The new CEE connector with integrated filter solves this problem by eliminating these wires and making a direct connection between the filtered connector and its metal shield, which is grounded to the panel cut-out. The fully integrated unit can be front or rear panel mounted directly where the power comes into the equipment.

The new FMAB CEE series is suitable for single phase AC applications. It extends the power entry module concept outlined in IEC 60320, where power input is limited to 16 A. Both the FMAB CEE and the FMAD CEE, which is designed for three phase applications, are rated from 16 up to 32 amperes. They are designed and approved according IEC 60309, UL 1283 and CSA 22.2 no. 8. The voltage rating is 250 VAC (IEC, UL, CSA) and 110 / 125 VAC (UL, CSA). The new filter series are suitable for use in industrial appliances exposed to temperatures ranging from -40 to +85C. Screw terminals provide for ease of installation.
