Product details

Four poles, rated 200 A continuous at 40 °C, with a maximum interrupting capacity of 187 kA at 240 V AC.

Rated 200 A at 40 °C, derated to 176 A at 70 °C — the thermal curve is linear, so if your panel ambient runs hot, the breaker's continuous current drops. Interrupting capacity steps down with voltage: 187 kA at 240 V, 121 kA at 415 V, 75.6 kA at 440 V, 30 kA at 500 V, and 17 kA at 690 V. That voltage-dependent curve is typical for MCCBs; the 690 V rating is still high enough for most 480/277 V or 600 V industrial services.

Panel integration and accessories

Dimensions: 140 mm wide, 158 mm tall, 70 mm deep — fits standard MCCB panel cutouts. The supplied basic switch is 3VA12205EF420AA0.
