The IMO Precision Controls UB10C1050A is a 50 Amp miniature circuit breaker (MCB). It is 1 pole with a C tripping curve, and 10kA short circuit capacity. Protects electrical installations in control panels and distribution systems from overloads and short circuiting. DIN rail mountable. UL 489 approved.
- Can be used for branch circuit device protection
- Thermo-magnetic overcurrent protection combines thermal overload protection with instantaneous magnetic tripping for rapid fault isolation
- Features contact position indicator
- C-Curve trip characteristic ideal for circuits with moderate inrush currents, such as small motor control circuits and transformers
