NB80 - 80Amp Circuit Breaker Description
NB80 - 80 Amp Circuit Breaker
The NB80 is a dependable 80 Amp, 2‑pole thermal magnetic circuit breaker designed to deliver consistent performance in residential and light commercial electrical systems. With a 10 kA interrupting rating at 120/240 VAC, this breaker is built to protect circuits from overloads and short‑circuit conditions with precision and confidence. Its compact form (approximately 4.25″ in height) and bolt‑on frame style make installation simple — especially when replacing older breakers that are no longer manufactured. Engineered as a direct aftermarket fit, the NB80 slides right into your existing panel without requiring modifications, making upgrades or repairs faster and more efficient.
This breaker’s thermal magnetic design blends heat‑based overload protection with magnetic response to sudden surges, helping safeguard your wiring and connected equipment. Whether you’re maintaining an older panel or refreshing a service entrance, the NB80 gives you reliable circuit interruption when you need it most.
