Product details

Siemens 3VA1040-4ED32-0AD0 — 40 A SENTRON MCCB with TM210 Release

The Siemens 3VA1040-4ED32-0AD0 is a 3-pole SENTRON molded case circuit breaker rated for 40 A continuous current at 40 °C, using a TM210 thermal-magnetic overcurrent release. It carries a 121 kA interrupting capacity at 240 V and 75.6 kA at 415 V, which means it can safely clear high-fault currents in distribution panels without upstream coordination issues.

Above 55 °C it drops to 38.4 A, and at 70 °C it reaches 36 A. The 121 kA at 240 V is the short-circuit current rating (SCCR) at that voltage; at 415 V it's 75.6 kA, and at 690 V it's 11.9 kA. These figures govern where the breaker can be installed in the fault-current hierarchy of the distribution board. It provides line protection (cable and busbar) rather than motor or generator protection.

The 3-pole design covers three-phase circuits; the neutral is not switched through this unit.

Frequently asked questions

Where can I buy 3VA1040-4ED32-0AD0 and get a price?

This part is sourced and quoted to order through independent distribution. Submit an RFQ for current pricing and availability — confirmed at quote time.

What is the depth of 3VA1040-4ED32-0AD0?

The depth is 70 mm.

What is the width of 3VA1040-4ED32-0AD0?

The width is 76.2 mm.

Will 3VA1040-4ED32-0AD0 drop into a panel specified for 3VA1010-2ED32-0JA0?

Both are 3-pole SENTRON MCCBs with the same 76.2 mm width and 70 mm depth, so the physical footprint is identical. The key difference is the current rating: the 3VA1040-4ED32-0AD0 is rated 40 A continuous, while the 3VA1010-2ED32-0JA0 is a lower-rated variant. Verify the load current and the TM release settings before substituting — the wiring and busbar must support 40 A.

What compliance documentation does Siemens provide for this MCCB?

The SENTRON series carries IEC 60947-2 certification as a molded case circuit breaker. RoHS and REACH declarations are standard from Siemens for this product line. Specific UL listing information should be confirmed against the nameplate marking on the unit.
