Product details

Above that, derate linearly: 194 A at 55 °C, 188 A at 60 °C, 182 A at 65 °C, 176 A at 70 °C (–).

Breaking capacity by voltage

187 kA at 240 V AC, 121 kA at 415 V AC, 75.6 kA at 440 V AC, 30 kA at 500 V AC, 17 kA at 690 V AC (–). These are the ultimate short-circuit interrupting ratings per IEC 60947-2. At 480 V (common North American industrial voltage) the 75.6 kA at 440 V is the closest published figure — conservative to use that for 480 V system fault duty.

Listed as current production. This is an active BOM-line part, not a phase-out item.

Dimensions: 140 mm wide, 158 mm high, 70 mm deep. Undervoltage release (UVR) is factory-fitted; two auxiliary switches (HQ type) are also included for remote status indication.
