Product details

It carries a continuous current rating of 250 A at 40 °C, derating to 223 A at 70 °C, which means the full 250 A is available in most standard panel environments — only above 55 °C does the rating start to drop.

Interrupting capacity across voltage levels

This 4-pole MCCB delivers 220 kA at 240 V, 154 kA at 415 V, 75.6 kA at 440 V, 30 kA at 500 V, and 17 kA at 690 V.

Integrated accessories and footprint

It measures 140 mm wide, 158 mm high, and 70 mm deep, which is the standard 4-pole SENTRON 3VA form factor.
