The E-T-A 104-PR3-1A is a miniaturized, single-pole thermal circuit breaker that ensures reliable switching behavior with its positively trip-free snap action mechanism. It meets the requirements of the EN 60934 (IEC 60934) standard.
This circuit breaker has a current rating of 1A and is designed for a maximum voltage of 240V AC or 48V DC. It is suitable for through-hole mounting and features a push-to-reset actuator type.
Typical applications for this thermal circuit breaker include hand tools, domestic appliances, overcurrent protection of PCB conductor paths, marine vehicles, and mobile homes. Its robust design also includes environmental resistance to shock, vibration, corrosion, and humidity.
Key technical specifications include an operating temperature range of -20°C to 60°C, an interrupting capacity of 6x IN (AC/DC), and a rupture capacity of 2000A (AC) or 200A (DC) under UL 1077 standards.
The breaker is rated for 240V AC and 48V DC operation.
The ambient temperature range is -20°C to 60°C.
It is designed for through hole mounting.
The interrupting capacity is 6 x IN for both AC and DC circuits.
IP40 at the operating area and IP00 at the terminal area.
It is a single-pole circuit breaker.
Electrical life varies: 3,000 cycles at 2 x IN for DC 28V, 1,000 cycles for 0.05-5A AC, and 50 cycles for 10A AC.
