Product details

This 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. For a 480 V panel, the 75.6 kA rating at 440 V is the closest published figure; the 30 kA at 500 V covers 480 V systems with margin. The 17 kA at 690 V suits European 690 V motor control centers.

Thermal derating and continuous current

Derating starts at 55 °C: 243 A, then 237 A at 60 °C, 230 A at 65 °C, and 223 A at 70 °C. Maximum power loss is 57 W. The 4-pole frame fits a 140 mm wide × 158 mm high × 70 mm deep footprint — standard for SENTRON 3VA plug-in or fixed mounting.

The basic switch supplied is 3VA12256EF420AA0. Trip indicator is not present; voltage trigger is present. This variant is configured for line protection with the shunt trip for remote opening — typical for emergency-off or interlocking circuits.
