Compared to the 3VA1110-5ED36-0AC0 (a 3-pole 100 A frame), the 3VA1140-5EF36-0BC0 is a 40 A continuous rating on the same mechanical platform — same 70 mm depth, same 76.2 mm width. The key difference is the lower amp rating paired with the same high-interrupting cassette (187 kA at 240 V), so you get selectivity headroom on a smaller load circuit without upsizing the panel cutout. Mounts in a standard SENTRON distribution panel or motor control center — DIN-rail or screw-mount baseplate, depending on the enclosure kit. The 3-pole block occupies three 18 mm module spaces (54 mm total on a DIN rail).","metaTitle":"Siemens SENTRON 3VA1140-5EF36-0BC0 MCCB, 40 A, 3-Pole, 187 k","metaDescription":"Siemens SENTRON 3VA1140-5EF36-0BC0 molded case circuit breaker, 40 A rated, 3-pole, line protection.
