E42B025L - 25Amp Circuit Breaker

E42B025L - 25 Amp Circuit Breaker

The E42B025L molded case circuit breaker is designed to provide dependable circuit protection for electrical distribution systems that require a 25-amp, 2-pole breaker within the E42 frame platform. Built for compatibility with equipment that uses this frame style, the breaker helps protect conductors and connected equipment from overloads and short circuits in commercial and industrial power systems. Rated for 18kA interrupting capacity at 480VAC and 25kA at 240VAC, this unit is suitable for installations where reliable fault interruption and stable operation are essential. The breaker includes both line-side and load-side terminals, helping streamline installation and replacement within existing panelboards or switchgear designed for this frame type. With HACR rating and operation up to 40°C ambient temperature, the E42B025L supports HVAC-related circuits and other standard distribution applications where consistent protection is required. Built with a molded case housing and durable internal components, this circuit breaker is intended to maintain proper form, fit, and function in compatible electrical systems. Electrical protection devices like the E42B025L are commonly used in facilities where equipment is expected to remain in service for many years, reflecting the long-lasting construction typical of molded case circuit breakers.
