E43B025L - 25Amp Circuit Breaker

E43B025L - 25 Amp Circuit Breaker

The E43B025L molded case circuit breaker is a 3-pole, 25-amp device designed to provide dependable overcurrent protection in commercial and industrial electrical distribution systems. Built on the E43 frame, this breaker supports interrupting capacities of 18kA at 480VAC and 25kA at 240VAC, making it suitable for protecting branch circuits and equipment operating within these voltage ranges. Rated for 40°C environments and HACR applications, the E43B025L is commonly used in HVAC-related electrical systems as well as general power distribution panels. The unit includes both line- and load-side terminals, simplifying installation and replacement within compatible panelboards or switchgear. Molded case construction helps ensure long service life, and the breaker is designed for straightforward form, fit, and functional replacement in systems originally configured for the E43 frame platform.
