NGB3B025B - 25 Amp Circuit Breaker

NGB3B025B - 25 Amp Circuit Breaker

The NGB3B025B is a 25 amp, 3-pole molded case circuit breaker for use in compatible panelboard applications. It is an NGB-type breaker rated 25 kA I.C. at 480VAC and 100 kA I.C. at 240VAC. The breaker measures 5 inches high, 3 inches wide, and 3.06 inches deep and includes load-side terminals. It is also HACR-rated and has a 40.25°C temperature rating. This breaker is a good fit for maintenance and replacement work on existing electrical equipment that was designed around the NGB3B025B or a breaker with the same required form, fit, and function. When replacing an older breaker, don't go by appearance alone. Check the part number, amp rating, poles, dimensions, mounting arrangement, voltage, and interrupting rating against the equipment you're working on. The NGB3B025B is built to last and provides a straightforward way to keep a compatible legacy installation running with the breaker configuration it was designed for.
