NEB3B110B - 110Amp Circuit Breaker

NEB3B110B - 110Amp Circuit Breaker

When you're replacing a breaker in an existing panelboard, getting the details right matters. The NEB3B110B is a Type NEB molded case circuit breaker rated at 110 amps with a 3-pole configuration. It measures 5.5 inches high, 3 inches wide, and 3 inches deep, and is designed for panelboard mounting. Electrical ratings include 35k AIC at 480VAC and 85k AIC at 240VAC. It's also HACR-rated, rated for 40°C, and includes load-side terminals. These specifications make the NEB3B110B a practical fit for compatible existing and legacy equipment where the breaker type, physical dimensions, mounting arrangement, and electrical ratings need to match. Its molded case construction is built to last when properly installed and used within its stated ratings. Before replacing an existing breaker, check the equipment requirements and nameplate information to make sure the NEB3B110B provides the correct form, fit, and function.

Where It Works Best

• The NEB3B110B is best suited to compatible panelboards and legacy electrical equipment that require a 110-amp, 3-pole Type NEB molded case circuit breaker with matching electrical and physical characteristics.
• It's a sensible choice for maintenance and replacement work where keeping the existing equipment configuration intact is important. You may encounter this type of breaker in commercial facilities, industrial environments, building maintenance operations, and compatible HVAC applications.
• The key is compatibility. Check the existing breaker and panelboard for the NEB type, 110A rating, three-pole configuration, mounting style, voltage, AIC rating, dimensions, and terminal arrangement. When those specifications match, the NEB3B110B provides the form, fit, and function the existing system requires.
