ECB34030G3 - 30Amp Circuit Breaker

ECB34030G3 - 30Amp Circuit Breaker

The ECB34030G3 PowerLink™ Circuit Breaker is designed for situations where dependable circuit protection and system compatibility matter most. This 30-amp, 3-pole thermal magnetic breaker is built for you to use in compatible PowerLink™ panelboards, offering a practical way to maintain existing electrical systems without changing the original setup or layout.

In real-world applications, this breaker is commonly used in commercial buildings, industrial facilities, and large-scale electrical systems where three-phase power distribution is required. Its bolt-on design allows for a secure fit inside compatible panelboards, helping you ensure consistent electrical performance in systems that are already in operation.

With interrupt ratings of 14kA at 480VAC and 65kA at 240VAC, the ECB34030G3 is suited for environments where electrical loads can vary and protection needs to remain reliable. The thermal magnetic trip mechanism responds to both overload conditions and short-circuit faults, helping protect downstream equipment and wiring.
