Product details

Line protection MCCB for the panel schedule

It carries 200 A at 40 °C, derating to 176 A at 70 °C. Breaking capacity is the headline spec for this class: 187 kA at 240 V AC, 121 kA at 415 V, and 75.6 kA at 440 V. That puts it well above typical utility fault levels for a 200 A frame, meaning it can be applied upstream in a distribution panel without worrying about cascading failure during a bolted fault. The 3-pole construction with a TM240 release trips on thermal overload and magnetic short-circuit.
