FB3015 - 15Amp Circuit Breaker

FB3015 - 15Amp Circuit Breaker

When your breaker fails, getting the right replacement is usually the fastest way to get equipment back in service. The FB3015 is a 15 Amp, 3-pole FB thermal-magnetic circuit breaker intended for compatible legacy electrical systems where matching the original specifications matters. Instead of changing panel components or making field modifications, you can install a breaker that matches the original form, fit, and function. That's especially important in facilities where downtime needs to be kept to a minimum.
