NGB2B070B - 70 Amp Circuit Breaker

NGB2B070B - 70 Amp Circuit Breaker

When you're replacing a circuit breaker in an existing panel, getting the details right matters. The NGB2B070B is a 70-amp, 2-pole Type NGB molded-case circuit breaker designed for compatible panelboard applications. It is rated 25k AIC at 480VAC and 100k AIC at 240VAC, measures 5.0" high x 2.0" wide x 3.06" deep, and includes load-side terminals. The breaker is also HACR rated and specified at 40.25°C. For maintenance work on older electrical systems, the NGB2B070B can be a good fit when the existing equipment calls for this breaker type and configuration. Before installation, confirm the part number, amperage, number of poles, dimensions, mounting style, voltage, and interrupting rating. Built to last, it gives contractors and maintenance teams a straightforward option for maintaining the form, fit, and function of compatible legacy equipment.
