NewTrend · DC contactor
Product overview
The NewTrend NR200A is a 200 A continuous-duty DC contactor with one normally open bridge contact, a maximum contact voltage of 80 V DC and an explicitly specified 15 V DC coil. Its cylindrical solenoid and steel mounting bracket suit battery-powered industrial vehicles and DC auxiliary power switching.
