E43B035L - 35Amp Circuit Breaker

E43B035L - 35 Amp Circuit Breaker

The E43B035L molded case circuit breaker is a 3-pole, 35-amp breaker designed to provide dependable circuit protection in commercial and industrial electrical distribution systems. Built on the E43 frame, this breaker is intended for installations that require consistent protection against overloads and short circuits while maintaining compatibility with existing equipment. With interrupting ratings of 18kA at 480VAC and 25kA at 240VAC, the E43B035L helps safeguard conductors and connected equipment by automatically interrupting fault conditions before damage occurs. It is HACR rated and designed for operation at 40°C, making it suitable for HVAC-related applications and other demanding environments where stable electrical protection is required. Line and load-side terminals are included, allowing for straightforward installation in compatible panelboards or distribution equipment. Built with durable molded case construction, this breaker is designed to provide long service life when used within its rated specifications.
