 Mini-contactors "BG" series 
 
The new miniaturised contactors of the BG series made by LOVATO ELECTRIC, meet the requirements of IEC/EN Std. 60947-4-1 and are cULus certified. 
Three versions have been designed with Screw, Faston and PCB-solder terminations
The same frame size for the models with direct current coil and alternating current coil the low comsumption rates and highly conductive auxiliary contacts are the highlights of the whole range.
For applications where the contactor is interfaced with electronic devices with control outputs with limited performance levels (e.g. PLC), a version with DC coil with very low comsumption is also available.
Power models are available in size from 6-9-12A in AC3 at 400V, with three-pole, four-pole versions (4NO or 2NO+2NC main poles), and control relay (4NO, 3NO+1NC, 2NO+2NC).
The accessories include: add-on block with 2 or 4 auxiliary contacts, quick-connect surge suppressor, mechanical interlock and rigid connections for making reversing and changeover contactor assemblies, power connection for fastening on SM1 circuit breakers..
The range is completed with a series of pre-assembled reversing and changeover contactor assemblies.

  • Model BGR: two contactors, with screw terminals, complete with external mechanical interlock, power connections (for inverting the phases), auxiliary connections (for making the electrical interlock). Further auxiliary contacts and surge suppressor may be added.

  • Model BGT : two contactors, with screw terminals, complete with built-in mechanical interlock and only power connections (the device is more compact in size). Further auxiliary contacts and surge suppressor may be added.

  • Model BGTS: two contactors, with PCB pins, complete with built-in mechanical interlock. The connections for reversing the phases are to be made on the printed circuit board.

A changeover assembly  is also available composed of two four-pole contactorsmechanically interlocked  for the changeover of supply lines.
