The E-T-A 104-PR-0.3A is a miniaturized, single-pole thermal circuit breaker designed for reliable switching behavior with a positively trip-free snap action mechanism. It meets the requirements of the circuit breaker standard EN 60934 (IEC 60934).
This circuit breaker has a rated voltage of 240 VAC and 48 VDC, with a current rating of 300mA. It is suitable for applications requiring overcurrent protection, such as hand tools, domestic appliances, PCB conductor paths, marine vehicles, and mobile homes. The actuator type is push to reset.
The device operates within an ambient temperature range of -20 to 60 °C and offers a degree of protection of IP40 in the operating area and IP00 at the terminal area. It has an interrupting capacity of 6 x IN for both AC and DC circuits and a rupture capacity of 2000A C1 for AC and 200A C1 for DC.
Mounting is through hole. The typical life is rated for 1,000 cycles at 2 x IN inductive for certain current ranges, with higher cycle counts specified for DC 28V operation.
