Mini contactors and relays

Three miniature components: 100-K contactor, 700-K control relay and 193-K bi-metallic overload relay have been added to the Modular Control System (MCS) product range.

The overload relay mounts directly onto the 100-K contactor, allowing starters to be assembled quickly. The total MCS Mini assembly occupies a small footprint, making it suitable in small industrial machines, HVAC and similar applications.

Rated to 690 V, the contactor and control relay feature a snap-in assembly system, allowing many different contactor configurations to be created. An IEC-rated front-pluggable mechanical interlock for AC and DC contactors allows the mounting of auxiliary contacts and suppressors on top, without tools. Bifurcated, self-cleaning auxiliary contacts provide a four-way current path for high contact reliability for low signal levels.

The contactor and control relay are also available with push-in termination for faster installation, plus improved long-term connection integrity in high-vibration environments. Modular wiring kits save time in building starter combinations.

The overload relay adds motor protection to the package. Compatible with AC- and DC-motors, the device features automatic, manual and remote reset functions, with differential release protecting motors in phase-loss, as well as overload conditions.
