Product details

The 200 A rating holds steady up to 50 °C; above that, it derates to 194 A at 55 °C, 188 A at 60 °C, 182 A at 65 °C, and 176 A at 70 °C, so the actual current you can run depends on your enclosure ambient. Breaking capacity is 121 kA at 240 VAC, 75.6 kA at 415 VAC, 52.5 kA at 440 VAC, 17 kA at 500 VAC, and 11.9 kA at 690 VAC. That means at a typical 400 V industrial service, you have over 75 kA of interrupting capability — enough for most high-fault locations like substation feeders or large motor starters.

The shunt trip allows remote tripping via a control signal, useful for emergency-stop circuits or undervoltage protection schemes. No communication function is built in, so remote monitoring requires the auxiliary contacts wired to an I/O module.

Frequently asked questions
