The MCCB carries its full 250 A rating up to 50 °C ambient; at 60 °C it derates to 232 A, and at 70 °C to 213 A. When sizing for a sealed or high-ambient panel, use the 60 °C or 70 °C figure — not the 40 °C number.
This order code includes 2 auxiliary switches (HQ type). The basic switch variant is 3VA2225-8HL32-0AA0. Maximum power loss is 48 W — a figure to budget for in panel thermal calculations.
The part is sourced to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time — submit an RFQ for a firm quote.
Continuous current is 250 A, breaking capacity is 440 kA at 240 V and 330 kA at 415 V. It is a 3-pole MCCB for line protection, with 2 auxiliary switches and no undervoltage release.
