HEB2B110B - 110Amp Circuit Breaker

HEB2B110B - 110Amp Circuit Breaker

The Siemens HEB2B110B is a 110 Amp, 2-pole molded case circuit breaker designed for compatible HEB (EG) frame low-voltage panelboard applications. When you're working with an existing electrical installation, the right replacement starts with matching the original specifications. Frame style, pole configuration, amperage, voltage rating, and terminal arrangement all need to align with the equipment already in place. This breaker features a thermal-magnetic trip unit to help protect your circuits from overloads and short circuits while fitting the requirements of compatible Siemens HEB frame systems.

Where It Works Best

The Siemens HEB2B110B is commonly used in commercial buildings, industrial facilities, and institutional electrical distribution systems that utilize compatible HEB (EG) frame panelboards. It is a good fit for repair and maintenance projects where the replacement breaker needs to match the existing equipment specifications. Keeping the same frame type, two-pole configuration, electrical ratings, and lug arrangement helps preserve the original panelboard layout and allows compatible equipment to remain in service.
