Product details

What this 500 A MCCB delivers

The Siemens 3VA1450-6GF42-0AA0 is a 4-pole SENTRON molded case circuit breaker rated for 500 A continuous at 40 °C, with a TM240 thermal-magnetic overcurrent release. The 220 kA interrupting rating at 240 V AC means it can clear a bolted fault at that level without the arc flashing upstream; at 415 V and 440 V it still holds 154 kA, and at 690 V it drops to 17 kA.

Derating and thermal reality

At 55 °C it derates to 488 A, at 60 °C to 476 A, at 65 °C to 464 A, and at 70 °C to 452 A. Maximum power loss is 122.7 W — that heat has to leave the enclosure, so factor it into your panel thermal calculation.

Dimensions: 184 mm wide, 248 mm tall, 110 mm deep. Four-pole frame, so it occupies the full width of a standard MCC bucket or a 600 mm wide enclosure section. Rated insulation voltage 800 V. Mounts with the standard SENTRON screw-clamp kit — verify the bus-bar adapter if you're feeding from a common bus.

Frequently asked questions

Where can I buy 3VA1450-6GF42-0AA0 and what is the lead time?

Sourced to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time — submit an RFQ for a firm lead-time commitment.

What is the closest functional second-source to 3VA1450-6GF42-0AA0?

The peer MPNs 5SQ2670-2YA63, 5SQ2670-2YA16, and 5SQ2670-0KA15 are listed as alternates. Verify the interrupting rating and release type against your coordination study before substituting — the 3VA1450 carries 220 kA at 240 V and 154 kA at 415 V, which may exceed the peer's SCCR.

What is the depth of 3VA1450-6GF42-0AA0?

110 mm (4.33 in). Combined with the 184 mm width and 248 mm height, it fits a standard 600 mm deep enclosure with room for rear bus bars.

Will 3VA1450-6GF42-0AA0 drop into a panel specified around 5SQ2670-2YA63 without rewiring?

The 3VA1450 is a 4-pole 500 A frame with a TM240 release; the 5SQ2670 peers are also 4-pole but may differ in mounting hole pattern and bus-bar spacing. Physical interchange is not guaranteed without checking the Siemens mounting template — the 184 mm width matches the standard SENTRON footprint, but verify the lug kit and terminal orientation against your existing bus.

What compliance documentation does Siemens provide for 3VA1450-6GF42-0AA0?

As a SENTRON MCCB, it carries CE marking for the European market and is designed to meet IEC 60947-2. RoHS and REACH declarations are standard from Siemens for this series. UL/CSA listing depends on the specific variant — confirm with the manufacturer's declaration for your region.
