Rated Trip Class 20, meaning it allows a motor to draw up to 20 times its full-load current for 20 seconds before tripping — appropriate for loads with moderate starting inertia like conveyors, pumps, and compressors. The breaker includes phase failure detection, which will trip if one phase is lost, preventing single-phasing damage to the motor. The voltage range spans 20 to 690 V, covering standard low-voltage motor circuits.
Width is 55 mm, depth 149 mm, height 140 mm. The 55 mm width occupies three 18 mm modular spaces on a DIN rail — a standard footprint for this class of motor-protective device. Main contact terminals accept 2x (0.5 to 1.5 mm²) or 2x (0.75 to 2.5 mm²) solid or stranded wire — sized for motor feeder cables up to 2.5 mm².
