E2050 - 50Amp Circuit Breaker

E2050 - 50 Amp Circuit Breaker

If you're maintaining an existing electrical system and need a breaker that fits right the first time, the E2050 circuit breaker delivers exactly that—no guesswork, no modifications. Built for dependable circuit protection, this 2-pole, 50-amp breaker is designed to match the form, fit, and function of Frame E systems already in place. Its thermal-magnetic trip mechanism responds to both overloads and short circuits with steady, predictable action, helping keep your equipment and wiring protected under normal operating conditions. With a 10 kA interrupting rating at 120/240 VAC and a 40°C temperature rating, it's a solid choice for everyday applications where consistency matters. And since load terminals are included, installation is straightforward—just what you want when time and accuracy count.
