Mounting position any, which helps when you're squeezing it into a gland-plate corner. Upwards and downwards clearance is 50 mm each; at the side it's only 10 mm, so you can pack breakers tight in a multi-motor group. Current production — the lifecycle stage is listed as active. This is not an NRND or obsolete part. No official successor exists because none is needed.","metaTitle":"Siemens 3RV2031-4XA15 SIRIUS Motor Protection Circuit Breake","metaDescription":"Siemens 3RV2031-4XA15 SIRIUS motor protection circuit breaker.
