This E-T-A 3120 series thermal circuit breaker is a 2-pole, 3A device rated for 240V AC operation. It features a green illuminated rocker actuator for clear status indication under 230V illumination voltage. The breaker utilizes a thermal mechanism for overcurrent protection, suitable for applications requiring reliable circuit interruption.
The panel mount design allows for easy installation in control panels and equipment enclosures. The rocker actuator provides manual on/off control with visual indication. The breaker complies with multiple safety standards including CSA C22.2 No 235, GB 17701, IEC 60934, and UL1077, ensuring broad regulatory acceptance.
Typical applications include industrial control systems, power distribution units, and machinery requiring robust circuit protection with user-friendly interface. The 3A current rating and 240V AC voltage rating make it suitable for moderate load protection in commercial and light industrial environments.
