ET4031 - 15Amp Circuit Breaker

ET4031 - 15Amp Circuit Breaker

When you're replacing a circuit breaker, matching the original electrical ratings and physical configuration is most important. The ET4031 molded case circuit breaker is a 15 Amp, 3-pole Type F breaker designed for 480VAC electrical distribution systems with a 14kA interrupting rating. It provides the overcurrent and short-circuit protection required in many commercial and industrial applications while helping maintain compatibility with existing equipment. Built for operation in 40°C ambient conditions, this molded case breaker is made to last and is well suited for maintenance, repair, and replacement projects where proper fit and function are essential. Whether installed in a panelboard, switchboard, or other compatible equipment, the ET4031 provides the electrical characteristics needed to keep existing systems operating as intended.
