NEB3B080B - 80Amp Circuit Breaker

NEB3B080B - 80Amp Circuit Breaker

When you're replacing a breaker in an existing panelboard, getting the details right matters. The NEB3B080B is a Type NEB, 80-amp, 3-pole molded-case circuit breaker made for compatible panelboard applications. It measures 5.5 inches high, 3 inches wide, and 3 inches deep so that you can compare its physical size with the breaker already in your equipment. Electrically, the NEB3B080B is rated 35kA at 480VAC and 85kA at 240VAC. It's also 40°C rated, HACR rated, and includes load-side terminals. For maintenance teams, electricians, and facility operators working with older electrical equipment, this breaker is a straightforward option when the existing system calls for the same NEB configuration and ratings. It's built to last for its intended use while providing the familiar form, fit, and function needed for compatible legacy installations. Before installation, always confirm the part number and electrical specifications against the breaker being replaced and the panelboard requirements.

Key Features and Benefits

• The available specifications provide no other material compliance information or certifications. If your application requires a particular approval, listing, or certification, check the breaker markings and confirm the equipment requirements before installation.
  

Where It Works Best

• The NEB3B080B makes the most sense when you're working on an existing panelboard or legacy electrical system that was designed for this breaker configuration. Instead of looking at amperage alone, compare the complete set of specifications: part number, breaker type, number of poles, voltage, A.I.C. rating, dimensions, mounting style, and terminal arrangement.
• It's also suited to compatible HACR applications that specify an 80-amp, 3-pole breaker with these ratings.
• For older electrical equipment, sometimes the goal is simple: find a breaker that matches what the system was designed to use. When the application calls for an NEB3B080B, this breaker provides the specified form, fit, and electrical function for compatible installations.
