It combines a thermal-magnetic overload relay and a high-breaking-capacity circuit breaker in one device, eliminating the need for separate components in the motor branch circuit. The breaker is rated for a supply voltage range of 20 to 690 V and offers a breaking capacity of 30 kA at 400 V — enough to handle most industrial fault levels without cascading upstream. Trip Class 20 means it allows a longer starting time for high-inertia loads (pumps, fans, conveyors) before tripping on overload.
The auxiliary contact ratings cover 24 V at 1 A, 60 V at 0.15 A, and 230 V at 0.5 A — enough to signal a trip to a PLC or annunciator. No ground-fault detection; if that's required, add an external ground-fault module.
The 55 mm width occupies three standard 18 mm module spaces, so plan your DIN-rail layout accordingly. Any mounting position is allowed. Main circuit terminals accept 2x (0.5 to 1.5 mm²) or 2x (0.75 to 2.5 mm²) solid or stranded wire. The main contact terminal size is M6.
