Rise in Circuit Breakers: Why It Matters Every circuit breaker generates heat during normal operation. When electrical current flows through the internal components\u2014contacts, bimetal strips, and terminals\u2014resistance creates thermal energy. While some heating is inevitable, excessive temperature rise can degrade insulation, accelerate contact wear, cause nuisance tripping, and ultimately lead to catastrophic failure.
