E43B035 - 35Amp Circuit Breaker

E43B035 - 35 Amp Circuit Breaker

The E43B035 molded case circuit breaker is designed to provide dependable overcurrent protection for electrical distribution systems that require a 35-amp, 3-pole breaker within the E43 frame series. Built for compatibility with existing equipment, this bolt-on circuit breaker is commonly used as a form, fit, and functional replacement in legacy commercial and industrial panelboards or switchboard assemblies. With interrupting ratings of 18kA at 480VAC and 25kA at 240VAC, it is suited for protecting circuits against overloads and short circuits in systems operating at common low-voltage levels. The unit includes load-side terminals for convenient installation and is HACR rated, making it suitable for heating, air conditioning, and refrigeration equipment applications where applicable. Designed to meet typical operating conditions of 40°C ambient environments, this molded case breaker provides the electrical protection and compatibility required to maintain and service established power distribution infrastructure.
