NEB2B110B - 110 Amp Circuit Breaker

NEB2B110B - 110 Amp Circuit Breaker

When you're replacing a breaker in an existing panelboard, the details have to line up. The NEB2B110B is a 110-amp, 2-pole molded-case circuit breaker for compatible panelboard applications using the NEB configuration. It carries an interrupting rating of 35k AIC at 480VAC and 85k AIC at 240VAC, is HACR rated, and includes load-side terminals. Physical size matters too, especially when you're working with an existing installation. This breaker measures 5.5 inches high, 2.0 inches wide, and 3.0 inches deep. For maintenance and replacement work, the NEB2B110B gives electricians and facility teams clear specifications to match against the breaker already in service. If your equipment calls for this part number and these ratings, it can provide the form, fit, and function needed to keep a compatible legacy system operating as intended. It's a straightforward breaker built to last and made for a specific job.

Where It Works Best

• The NEB2B110B is best suited to existing panelboards and legacy electrical systems designed for an NEB Type 110-amp, 2-pole molded-case circuit breaker with matching dimensions and electrical ratings.
• It's especially useful in maintenance and replacement situations where the goal is simple: match the breaker the equipment was designed to use. That means checking more than the 110 amp rating. The number of poles, mounting arrangement, physical size, terminal configuration, voltage, and AIC rating must all match the application.
• For equipment requiring the NEB2B110B configuration, this breaker offers the appropriate form, fit, and function without making unnecessary claims about how it compares with other breaker designs.
• Always verify the part number, amperage, poles, voltage, AIC rating, dimensions, mounting style, and terminal configuration against the existing equipment. A qualified electrical professional should determine installation and final application suitability in accordance with applicable electrical codes.
