Designed for motor protection, it combines a circuit breaker and overload relay in one device — Class 10 trip curve so it tracks the thermal characteristic of a standard induction motor during start-up, protecting against overload and short circuit without nuisance tripping on normal inrush. Rated at 20 A continuous at 480 V and 600 V, it handles motors up to 10 hp at 460/480 V, 15 hp at 575/600 V, and 5 hp at 220/230 V. No ground fault detection on this variant. The main circuit uses spring-loaded terminals.
Lifecycle status is current production. This is an active catalog line, sourced through standard Siemens distribution.
Panel integration: S0 frame width is 45 mm, depth 97 mm, height 119 mm. Clearance requirements are 50 mm upwards, 50 mm downwards, 30 mm at the side — tight for a 45 mm wide device, so adjacent components can sit close.
