Its TM210 thermal-magnetic release provides fixed overload and short-circuit protection without adjustment — set it and forget it for standard feeder or branch circuits. Breaking capacity hits 75.6 kA at 240 V, tapering to 52.5 kA at 415 V and 32 kA at 440 V — enough headroom for most industrial panelboards with high fault current upstream. Dimensions are 76.2 mm wide, 130 mm tall, 70 mm deep — a standard 3-pole MCCB footprint that fits SENTRON panelboard mounting bases and most DIN-rail adapters.
At 40 °C the breaker carries a full 25 A. Derating is minimal through 50 °C (still 25 A), then drops to 24 A at 55–60 °C, and 23 A at 65–70 °C. That's a shallow curve — usable in warm cabinets without oversizing. Maximum power loss is 8.5 W per pole, manageable for thermal coordination in a packed panel.
