Product details

MCCB for line protection — 250 A, 4-pole, high interrupting capacity

Interrupting capacity is 220 kA at 240 V AC, 154 kA at 415 V, 75.6 kA at 440 V, 30 kA at 500 V, and 17 kA at 690 V — figures that cover most low-voltage fault scenarios without cascading upstream.

Thermal derating and operating envelope

Above that, it derates linearly: 243 A at 55 °C, 237 A at 60 °C, 230 A at 65 °C, and 223 A at 70 °C. Maximum power loss is 57 W. These limits govern the breaker's placement in unconditioned enclosures or outdoor-rated panels.

The 4-pole width occupies roughly 5.5 inches of rail space — plan the enclosure layout accordingly.
