Product details

Breaking capacity is voltage-dependent: 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.

Thermal derating and power loss

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 at rated current — relevant for enclosure heat calculations in a densely packed panel.

Physical fit and integration

The shunt trip release (STL) allows integration with emergency-stop circuits or undervoltage protection schemes — no separate undervoltage release is fitted on this variant.
