Product details

The Siemens SENTRON 3VA1110-5EF42-0AA0 is a 4-pole molded case circuit breaker (MCCB) rated 100 A continuous at 40 °C with a TM240 thermal-magnetic release. The 4-pole design covers three-phase plus neutral switching, which matters for TN-S or TN-C-S systems where the neutral must be isolated on fault clearing.

Panel fit and mounting — dimensions and integration

The 3VA1110-5EF42-0AA0 measures 130 mm high, 101.6 mm wide, and 70 mm deep. The 101.6 mm width (4 inches) is the standard 4-pole MCCB footprint in the SENTRON 3VA platform, so it occupies the same DIN-rail or screw-mount space as other 4-pole 3VA frames. Depth of 70 mm (2.76 in) leaves enough clearance for rear-connection busbars or plug-in adapters in a typical 600 mm deep enclosure. Front IP40 protection means the breaker is splash-proof from the front but not sealed; install it in a panel with an IP54 or better door if washdown is present.

Frequently asked questions

What is the closest functional second-source to 3VA1110-5EF42-0AA0?

The 3VA1110-5EF36-0AD0 is the closest peer — same 100 A frame, 4-pole, TM240 release. The difference is in the breaking capacity at specific voltages; verify the interrupting rating at your system voltage before substituting.

Will 3VA1110-5EF42-0AA0 drop into a panel specified around 3VA1110-5EF36-0AD0 without rewiring?

Yes — both are 4-pole 100 A MCCBs with the same 101.6 mm width and 130 mm height, so the mounting footprint and busbar connections are identical. The depth is also 70 mm on both. No rewiring needed for the same panel cutout.
