DC-rated miniature circuit breaker for industrial DC distribution
It is designed specifically for DC circuits up to 880 V (rated) and a maximum of 1 000 V DC, with a breaking capacity of 10 kA at 880 V DC per IEC 60947-2. Four poles in series give the voltage withstand for 880 V DC; polarity must be observed on the supply side.
Mounts via the quick-assembly system onto DIN rail — standard 4 width units (72 mm wide). Screw terminals torque to 2.5–3.5 N·m (22–31 lbf·in). IP20 with conductors connected; touch protection is built in. Halogen-free and silicon-free construction, sealable for tamper-proofing. Humidity tolerance up to 95% at 55 °C, derated at higher temperatures.
