E43B060L - 60Amp Circuit Breaker

E43B060L - 60 Amp Circuit Breaker

When you’re maintaining or servicing an electrical system built around the E43 frame, the E43B060L molded case circuit breaker offers a straightforward form, fit, and function replacement designed to keep those systems operating as intended. Rated at 60 amps with a 3-pole configuration, this breaker is commonly used in three-phase distribution systems found in commercial and industrial facilities. It provides dependable overcurrent protection with interrupting ratings of 18kA at 480VAC and 25kA at 240VAC, helping protect wiring and connected equipment when overloads or short circuits occur. Built with molded case construction and designed to operate at 40°C, the E43B060L is also HACR rated, which makes it suitable for heating, air conditioning, and refrigeration circuits where that classification is required. Electricians and maintenance professionals appreciate the practical design, including line and load-side terminals that come included, allowing for easier integration into compatible equipment. Simply put, this breaker is built to last and designed to match the electrical characteristics required by systems that rely on the E43 frame format.
