Description
The Siemens BRKB3100 is a 3‑pole, 100A, bolt‑on molded‑case circuit breaker engineered for dependable protection in commercial and industrial electrical distribution panels. Part of Siemens’ BRK/BL‑style bolt‑on breaker family, it features a thermal‑magnetic trip mechanism that safeguards circuits from overloads and short circuits while maintaining stable performance under continuous load. The bolt‑on mounting design ensures a secure, vibration‑resistant connection to the bus, making it suitable for harsher environments and high‑demand applications. With its 240V AC rating, durable molded housing, and Siemens’ proven reliability, the BRKB3100 is a solid choice for panelboard upgrades, replacements, and new installations requiring a robust 3‑pole 100‑amp breaker.
