NGB2B110B - 110 Amp Circuit Breaker

NGB2B110B - 110 Amp Circuit Breaker

Finding the right breaker for an existing panelboard often comes down to the details. The NGB2B110B is a 110-amp, 2-pole Type NGB molded-case circuit breaker for compatible panelboard applications. It has an interrupting rating of 25k AIC at 480VAC and 100k AIC at 240VAC, and measures about 5.0 inches high, 2.0 inches wide, and 3.06 inches deep. The breaker is HACR-rated, specified at 40.25°C, and comes with load-side terminals. Those details are especially useful when you're replacing a breaker in an existing or legacy installation, where getting the correct physical configuration and electrical ratings is essential. For maintenance teams, electricians, and facilities working with equipment designed around Type NGB breakers, the NGB2B110B provides the familiar form and function needed to keep the existing setup intact. It's a straightforward, purpose-built breaker that's built to last when used within its intended ratings and application.

Key Features and Benefits

• 110-amp rating for applications that require a 110A breaker.

Where It Works Best

• The NGB2B110B makes the most sense in existing panelboards and legacy electrical systems designed for a Type NGB molded case circuit breaker. It's particularly relevant when a maintenance or replacement job calls for a 110A, 2-pole breaker with the same mounting arrangement, dimensions, and electrical characteristics.
• Its HACR rating can also make it suitable for certain heating, air-conditioning, and refrigeration applications, provided the equipment calls for these specifications.
• When matching a breaker to existing equipment, don't rely on amperage alone. Check the NGB2B110B part number, 110A rating, two-pole configuration, AIC and voltage ratings, physical dimensions, mounting style, and terminal arrangement against the panelboard or equipment requirements. This helps ensure you select the correct form, fit, and function for the application.
