Breaking capacity reaches 220 kA at 240 V AC, 154 kA at 415 V and 440 V, 121 kA at 500 V, and 17 kA at 690 V — figures that cover most industrial distribution panels and motor control centers.
Maximum power loss 92.1 W at rated load, which drives enclosure ventilation requirements.
This part is sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time.
The breaking capacity is 220 kA at 240 V AC, with derated values at higher voltages: 154 kA at 415 V and 440 V, 121 kA at 500 V, and 17 kA at 690 V.
Yes, it is factory-fitted with an undervoltage release (UVR) and two HP auxiliary switches.
