This E-T-A 104-PR2-3A is a single pole thermal circuit breaker in a miniaturized design. It features a positively trip-free snap action mechanism for reliable switching behavior and meets the requirements of the circuit breaker standard EN 60934 (IEC 60934).
The breaker has a current rating of 3A and supports voltage ratings of up to 240 VAC and 48 VDC. It is designed for through-hole mounting.
Typical applications for this type of circuit breaker include hand tools, domestic appliances, overcurrent protection of PCB conductor paths, marine vehicles, and mobile homes. The datasheet indicates a typical life of 1,000 cycles at 2 x IN for currents up to 5A, decreasing for higher current ratings.
Environmental specifications include an operating temperature range of -20 to 60 °C, an ingress protection rating of IP40 for the operating area, and resistance to vibration, shock, corrosion, and humidity.
