Product details

What this 3VA2 carries

The Siemens SENTRON 3VA2463-6JQ32-0CL0 is a 3-pole molded case circuit breaker (MCCB) rated for line protection. It handles 630 A continuous at 40 °C, with a thermal derating curve that drops to 450 A at 70 °C — useful for hot panel environments. The interrupting capacity reaches 242 kA at 240 V, 187 kA at 415/440 V, 121 kA at 500 V, and 40 kA at 690 V, so it can sit upstream of high-fault switchgear without cascading. The ETU560 electronic trip unit gives adjustable long-time, short-time, instantaneous, and ground-fault protection, plus a communication function for remote monitoring.

Panel fit and dimensions

Mounts on a DIN rail or panel-mount plate. Dimensions are 248 mm high, 138 mm wide, 110 mm deep — check the gland plate clearance on the depth, especially with the auxiliary switch block fitted. The auxiliary contact configuration includes 2 auxiliary switches, 1 trip alarm switch, and 1 electrical alarm switch (HQ type), all wired via the supplied basic switch 3VA2463-6JQ32-0AA0.

Frequently asked questions

Where can I buy 3VA2463-6JQ32-0CL0 and get a price?

This part is sourced to order against an RFQ through independent distribution. Submit a request for quote (RFQ) — availability and current pricing are confirmed at that time.

What is the interrupting capacity at 240 V?

The rated ultimate short-circuit breaking capacity Icu is 242 kA at 240 V AC. At 415/440 V it is 187 kA, at 500 V it is 121 kA, and at 690 V it is 40 kA.

What trip unit does this MCCB use?

It uses the ETU560 electronic trip unit, which provides adjustable LSI (long-time, short-time, instantaneous) protection plus ground-fault protection via summation current formation on the L-conductor.
