Product details

The Siemens SENTRON 3VA2225-5KP32-0KH0 is a 3-pole molded case circuit breaker rated for 250 A continuous current at 40 °C, with an adjustable thermal-magnetic trip range from 375 A up to 2500 A — meaning you set the trip point to match the downstream conductor or load, not the breaker's own frame limit. Interrupting capacity runs 187 kA at 240 V, drops to 121 kA at 415 V and 440 V, then 75.6 kA at 500 V, and 4.5 kA at 690 V — so at typical 480 V distribution levels it clears faults well above most service-entrance requirements. The auxiliary switch configuration is two auxiliary contacts plus one trip-alarm switch HQ.

Derating and thermal reality

At 55 °C it derates to 238 A, at 60 °C to 225 A, at 65 °C to 213 A, and at 70 °C to 200 A — so in a warm panel or outdoor enclosure you must reduce the load or increase the breaker frame size accordingly. Maximum power loss is 48 W.

Dimensions are 105 mm wide (4.13 in), 181 mm tall (7.13 in), 86 mm deep (3.39 in).

Frequently asked questions

What is the closest functional second-source to 3VA2225-5KP32-0KH0?

The peer MPN 3VA2225-5JQ32-0AK0 is a similar SENTRON 3-pole MCCB in the same frame size, but the exact auxiliary switch configuration and release options differ — verify the auxiliary contact count and shunt trip fit before substituting.

What is the interrupting capacity of this breaker at 480 V?

At 440 V and 500 V, the interrupting capacity is 121 kA and 75.6 kA respectively — at 480 V it falls between those two values, so expect roughly 100 kA class performance at typical 480 V distribution.

How do I get current pricing and availability for 3VA2225-5KP32-0KH0?

This part is sourced and quoted to order against an RFQ through independent distribution. Submit a request for quote (RFQ) to confirm current pricing and availability at the time of order.

What compliance documentation does this brand provide for 3VA2225-5KP32-0KH0?

Siemens SENTRON MCCBs typically carry UL 489, CSA C22.2 No. 5, and IEC 60947-2 certifications, plus RoHS and REACH compliance declarations — specific documentation is provided at order or on request.
