The E-T-A 104-PR-0.7A 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 EN 60934 (IEC 60934) for R-Type, TO circuit breakers.
This circuit breaker has a current rating of 700mA and is suitable for a rated voltage of 240V AC or 48V DC. It is designed for through-hole mounting and features a push-to-reset actuator.
Typical applications for this thermal circuit breaker include hand tools, domestic appliances, overcurrent protection of PCB conductor paths, marine vehicles, and mobile homes. The device offers an operating area protection of IP40 and terminal area protection of IP00.
Key technical data includes an ambient temperature range of -20 to 60 °C, an interrupting capacity of 6 x IN for both AC and DC, and a rupture capacity of 2000A C1 for AC and 200A C1 for DC under UL 1077 standards. The typical life varies based on current rating and load conditions, with up to 3,000 cycles at 2 x IN inductive for DC 28V.
