HEB3B015B - 15Amp Circuit Breaker

HEB3B015B - 15Amp Circuit Breaker

The Siemens HEB3B015B is a 15 Amp, 3-pole molded case circuit breaker used in compatible HEB (EG) frame low-voltage panelboards. When you're replacing a breaker in an existing system, matching the original specifications is what matters most. The frame type, number of poles, amp rating, voltage rating, and lug arrangement all need to match the existing installation. This model uses a thermal-magnetic trip unit to help protect your circuits from overloads and short circuits while keeping the original HEB frame requirements in place.
