That SCCR headroom lets it sit upstream in a high-fault panel without cascading to a larger frame — a real advantage when coordinating with downstream motor starters or smaller branch breakers. The basic switch (3VA21407MN360AA0) is pre-assembled with two auxiliary switches plus a trip alarm switch (HQ), so you get status feedback without adding external contact blocks.","metaTitle":"Siemens 3VA2140-7MN36-0BH0 SENTRON MCCB, 40 A, 3-Pole, 330 k","metaDescription":"Siemens 3VA2140-7MN36-0BH0 SENTRON molded case circuit breaker, 40 A, 3-pole, 330 kA interrupting at 240 V.
