Four poles cover three-phase plus neutral, and the shunt trip (STL) allows remote tripping. Breaking capacity hits 220 kA at 240 V, 154 kA at 415 V, 36 kA at 440 V, and 17 kA at 690 V — so it handles high-fault utility feeds and transformer secondaries.
At 55 °C it derates to 243.3 A, at 60 °C to 236.5 A, at 65 °C to 229 A, and at 70 °C to 223 A.
Sourced and quoted to order against an RFQ through independent distribution; availability and pricing confirmed at quote time.
