NEB2B100B - 100 Amp Circuit Breaker

NEB2B100B - 100 Amp Circuit Breaker

When your existing equipment calls for an NEB2B100B, getting the specifications right matters. This 100-amp, 2-pole molded-case circuit breaker is an NEB Type breaker made for compatible panelboard-mounted applications. It carries an interrupting rating of 35k AIC at 480VAC and 85k AIC at 240VAC and measures approximately 5.5 inches high, 2 inches wide, and 3 inches deep. The breaker is HACR rated, has a 40.25°C temperature rating, and comes with load-side terminals. For maintenance and replacement work, the NEB2B100B makes sense when the existing electrical system requires this particular combination of amperage, poles, mounting style, dimensions, and interrupting ratings. It's a straightforward molded case breaker designed to provide the form, fit, and function compatible equipment requires—and it's built to last when installed and used within its specified ratings.

Where It Works Best

• The NEB2B100B 100 amp, 2-pole circuit breaker is intended for compatible panelboards and electrical distribution equipment that require an NEB Type molded case breaker with these specifications. It can be a practical fit for maintenance, repair, and replacement work, particularly in existing or legacy electrical systems where keeping the correct breaker configuration is important.
• Before installation, compare more than the part number. Check the amperage, number of poles, voltage, and AIC ratings, mounting arrangement, physical dimensions, and terminal configuration against the breaker being replaced and the equipment requirements. That extra check helps ensure the NEB2B100B is the right form, fit, and functional match for the application.
