The E-T-A 104-PR2-1A is a miniaturized, single-pole thermal circuit breaker designed for reliable switching behavior. It meets the requirements of the EN 60934 (IEC 60934) standard.
This circuit breaker has a current rating of 1A and can operate at up to 240V AC or 48V DC. It features a push-to-reset actuator and a through-hole mounting type, making it suitable for various applications.
Typical applications include hand tools, domestic appliances, overcurrent protection of PCB conductor paths, marine vehicles, and mobile homes. The device offers a degree of protection of IP40 in the operating area and IP00 at the terminal area.
Environmental and mechanical specifications include resistance to vibration, shock, corrosion, and humidity, ensuring durability in demanding environments. The thermal tripping mechanism provides overcurrent protection.
The 104-PR2-1A is rated for 240VAC and 48VDC.
The ambient operating temperature range is -20 to 60°C.
The mounting type is through hole.
The actuator type is push to reset.
The interrupting capacity is 6 times the rated current (6x IN) for both AC and DC circuits.
The degree of protection is IP40 for the operating area and IP00 for the terminal area.
Typical life varies from 50 to 3000 cycles depending on load conditions, with 1000 cycles at 2x IN inductive and 3000 cycles at 28VDC.
