Circuit Breakers Overview


Thermal & Magnet Circuit Breakers
Our extensive P&B circuit breaker product line includes thermal and magnetic types. Termed secondary breakers by UL, they protect equipment rather than branch circuits in buildings. One- to four-pole models are available in current ratings from milliamps through 50 amps.

All series in this product line meet the requirements of UL 1077, and recent enhancements allow several models to also meet ignition protection requirements according to UL 1500.
