NEB1B100B - 100Amp Circuit Breaker

NEB1B0100B - 100 Amp Circuit Breaker

Looking for an NEB1B0100B to match an existing panelboard application? This is a 100-amp, single-pole molded-case circuit breaker in the Type NEB configuration. It has an interrupting rating of 35 kA.I.C. at 277VAC and 85 kA.I.C. at 120VAC, along with a 40°C rating and HACR rating. The breaker is panelboard-mounted and includes load-side terminals. Size is another detail to check before replacing an existing breaker: the NEB1B0100B measures about 5.5 inches high, 1 inch wide, and 3 inches deep. For maintenance on older electrical equipment, those details can matter as much as the amp rating; if your equipment calls for this specific NEB configuration, the NEB1B0100B provides the familiar form, fit, and electrical function you need. It's a straightforward circuit breaker built to last and designed to do the job it was made for.

Material Compliance and Certifications

• The NEB breaker family carries applicable manufacturer-documented approvals and markings, including UL, CSA, IEC, and CE, with applicable interrupting ratings documented under UL 489/CSA requirements. The NEB family is also identified as HACR-rated within its applicable amperage range.
• Because electrical equipment can vary by application, don't go by appearance alone. Check the breaker markings and compare them with the panelboard requirements, equipment documentation, and applicable electrical codes.

Where It Works Best

• The NEB1B0100B is intended for compatible panelboards and existing electrical distribution equipment that require a 100 amp, 1-pole Type NEB circuit breaker with these dimensions and electrical ratings.
  
• This can be especially useful when you're maintaining an older installation and need to stay with the breaker configuration the equipment was designed around. The key is a proper match: check the part number, amperage, poles, voltage, A.I.C. rating, mounting style, dimensions, and terminal setup.
  
• For the right application, the NEB1B0100B keeps things simple—you get the required breaker configuration without trying to make a different breaker style fit equipment it wasn't designed for.
