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.","metaTitle":"Siemens 3VA1110-5EF42-0AA0 SENTRON MCCB, 100 A, 4-Pole, TM24","metaDescription":"Siemens SENTRON 3VA1110-5EF42-0AA0 molded case circuit breaker, 100 A, 4-pole, TM240 release.
