Q1B3100 - 100 Amp Circuit Breaker

Q1B3100 - 100 Amp Circuit Breaker

When you're replacing a breaker in an existing electrical system, getting the details right matters. The Q1B3100 is a 100-amp, 3-pole bolt-on thermal-magnetic circuit breaker designed for equipment that accepts Type Q1B breakers. It carries a 10 kA I.C. rating at 240 VAC and requires six spaces. Physical dimensions are 6.38 inches high, 2.25 inches wide, and 2.31 inches deep. For maintenance work on compatible legacy equipment, the Q1B3100 can provide the form, fit, and electrical ratings needed to match the existing application. Its thermal-magnetic design responds to overload and short-circuit conditions, while the bolt-on connection matches equipment built for this mounting style. It's a straightforward breaker built to last and intended to perform its specified function when correctly matched to the electrical system.

Key Features and Benefits

• 100-amp rating for applications designed around a 100A breaker.
