NGB2B025B - 25 Amp Circuit Breaker

NGB2B025B - 25 Amp Circuit Breaker

When you're replacing a breaker in an existing panelboard, getting the details right matters. The NGB2B025B is a Type NGB molded case circuit breaker rated at 25 amps with 2 poles. It's designed for panelboard mounting and measures 5.0 inches high, 2.0 inches wide, and 3.06 inches deep, so you can easily compare its dimensions with the breaker already in your equipment.

The NGB2B025B carries an interrupting rating of 25k AIC at 480VAC and 100k AIC at 240VAC. It's also HACR-rated, rated for 40.25°C, and comes with load-side terminals. This breaker is built to last and is a practical fit for compatible electrical equipment, especially older systems designed around Type NGB breakers. If you're replacing an existing unit, check the part number and electrical ratings along with the physical size and mounting style. A breaker that looks similar isn't necessarily the right match.

Material Compliance and Certifications

• The NGB2B025B is HACR rated and has a specified temperature rating of 40.25°C. No other material-compliance or certification information has been provided for this part number, so do not assume additional certifications.
• For installations with specific compliance or code requirements, confirm the breaker markings and the requirements of the equipment where it will be installed.
  

Where It Works Best

• The NGB2B025B is best suited to compatible panelboards and existing electrical distribution systems that use Type NGB circuit breakers. It's especially relevant when maintaining older equipment where changing breaker types isn't the goal—you need the correct form, fit, and electrical characteristics for the application.
• Before replacing an existing breaker, compare more than the amperage. Check the NGB2B025B part number, 2-pole configuration, voltage and AIC ratings, dimensions, panelboard mounting, and terminal arrangement against the equipment requirements. These details determine whether the breaker fits the job.
