Rated at 52 A at 480 V and 52 A at 600 V, this breaker handles common North American motor sizes in those voltage classes. At 230 V it supports a 10 hp motor. The breaking capacity is 30 kA at 400 V AC, 100 kA at 240 V, and 2 kA at 690 V — so it safely interrupts fault currents up to those levels without upstream coordination issues in most industrial distribution. Trip class is CLASS 20, meaning it allows up to 20 seconds to trip under locked-rotor conditions — standard for general-purpose pumps, fans, and compressors that don't need the faster CLASS 10 protection. Maximum switching frequency is 15 operations per hour under AC-3 (motor) duty, which suits cyclic loads like conveyors or batch mixers. No ground fault detection on this variant.
