Siemens B250 Bolt On 2 Pole Circuit Breaker 50A

Siemens B250 is a two‑pole, 50 A bolt‑on molded‑case circuit breaker from the BL series, designed for 120/240 VAC panels and delivering a 10 kA interrupt rating. This common‑trip device mounts bolt‑on into BL‑type panelboards and uses load‑lug terminals suitable for 8–6 AWG conductors, making it a solid choice for residential or light commercial distribution circuits. Measuring roughly 4 inches long, 3 inches wide, and 2 inches high, it fits standard BL frame space and supports panelboard mounting with thermal/magnetic overcurrent protection for each circuit. The B250 is specified for 2‑pole operation in BL installations, providing reliable protection for multi‑wire branch circuits in compatible Siemens systems.
