The 3120-F321-P7T1-W02D-2.5A is a thermal circuit breaker produced by E-T-A. It is designed to provide overcurrent protection in electrical circuits, with a current rating of 2.5A. The device is rated for 250VAC and 50VDC operation, making it suitable for a range of AC and DC applications. The breaker features a panel mounting type and a rocker actuator, with two poles for circuit interruption. It complies with multiple safety standards including CSA C22.2 No 235, GB 17701, IEC 60934, and UL1077. Its typical operational life is approximately 30,000 operations under specified conditions. The device is designed to operate within an ambient temperature range of -30°C to 60°C and offers insulation coordination of 2.5 kV with reinforced insulation. It provides dielectric strength of 3,000 VAC pole to pole and 1,500 VAC in the operating area, with insulation resistance exceeding 100 MΩ. The breaker has an IP40 degree of protection, with options for IP54 or IP66 in terminal areas with water splash cover. It is suitable for circuit protection in various electrical systems, especially where thermal overcurrent protection is required.
