MXSB current sensing contactor

For rugged environments, off-road and tracked vehicles. When the trip limit is exceeded the contacts will open and the Trip indicator line will go low. The TRIP pin is an open drain. After a trip, V-control needs to be brought low to reset the contactor. Current trip setting range ±20-600 Amp. Current Sense: Indicates the current through the main contacts (A2 and A1). The current sense range is from -600 to +600 Amps (0V to 5V).
