HEB3B030B - 30Amp Circuit Breaker Description
HEB3B030B - 30Amp Circuit Breaker
The Siemens HEB3B030B is a 30 Amp, 3-pole molded case circuit breaker built for compatible HEB (EG) frame low-voltage panelboard applications. When you're replacing an existing breaker, matching the original equipment is the most important step. The frame style, number of poles, amp rating, voltage rating, and lug configuration all need to line up with the installed system. This breaker uses a thermal-magnetic trip unit to help protect against overloads and short circuits while keeping the same HEB frame requirements as the original application.

Where It Works Best
The Siemens HEB3B030B is commonly used in commercial, industrial, and institutional electrical distribution equipment that uses compatible HEB (EG) frame panelboards. It is a good match for maintenance and replacement projects where the existing breaker needs to maintain the same electrical and physical characteristics. Keeping the original frame style, three-pole configuration, ratings, and connection points helps avoid changes to the existing panelboard setup.
