Product details

The Siemens 3VA1040-2ED32-0AF0 is a SENTRON molded case circuit breaker (MCCB) rated 40 A at 40 °C, with a 3-pole configuration and a TM210 thermal-magnetic overcurrent release. Breaking capacity reaches 52.5 kA at 240 V AC and 32 kA at 415 V AC — sufficient for high-fault-current service entrances and industrial sub-distribution boards where SCCR coordination is critical.

At 70 mm deep, 76.2 mm wide, and 130 mm tall, this MCCB fits standard SENTRON 3VA mounting footprints. Width matches the 3-pole form factor for DIN-rail or screw-mount panel integration. Maximum power loss of 10.8 W at rated current informs enclosure thermal budgeting.

Frequently asked questions

What overcurrent release does this MCCB use?

A TM210 thermal-magnetic release with fixed trip settings — no adjustment dials, reducing commissioning variables.
