Rated continuous current Iu is 25 A at 40 °C, with a TM240 thermal-magnetic overcurrent release that handles the overload and short-circuit trip curve. Breaking capacity hits 187 kA at 240 V and 121 kA at 415 V — that's the fault current it can safely interrupt without welding contacts or cascading upstream. Rated insulation voltage is 800 V, so it's comfortable in 480 V / 600 V panels.
Three poles, no undervoltage release, no shunt trip, no ground-fault monitoring — this is a straight thermal-magnetic breaker for basic feeder or branch protection. The 25 A continuous rating holds flat through 50 °C; above that it derates to 24 A at 55 °C and 22.5 A at 70 °C. The TM240 release is fixed, not adjustable — you get one trip curve, no dials.
No communication module, no phase-failure detection — it's a standalone breaker. Physical dimensions: 70 mm deep, 76.2 mm wide, 130 mm tall. Operating range is -25 °C to 70 °C, storage from -40 °C to 80 °C.
