The E-T-A 104-P30-5A 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 range from 0.05 A to 10 A, specifically rated at 5A for this model. It offers an interrupting capacity of 6x IN for both AC and DC circuits. The device is suitable for applications requiring overcurrent protection, such as hand tools, domestic appliances, PCB conductor paths, marine vehicles, and mobile homes.
Key technical specifications include a typical operating temperature range of -20 °C to 60 °C, a dielectric strength of 3000 VAC, and an insulation resistance greater than 100 MΩ at 500 VDC. It also features ingress protection ratings of IP40 for the operating area and IP00 for the terminal area. The breaker is designed for through-hole mounting and has a push-to-reset actuator.
Environmental and mechanical robustness are supported by resistance to vibration (10 g), shock (25 g), and corrosion (96 hours salt mist). The typical life is rated at 3000 cycles at 2x IN for lower currents and DC 28V, decreasing for higher currents.
The rated voltage is 240 VAC and 48 VDC.
The 104-P30-5A is a 5 A variant; the series current rating range is 0.05 A to 10 A.
The interrupting capacity is 6 x IN for both AC and DC operation.
The UL 1077 rupture capacity is 2000 A at AC 250 V and 200 A at DC 48 V.
The operating temperature range is -20 °C to 60 °C.
The operating area is IP40 and the terminal area is IP00.
The dielectric strength is 3000 VAC at the actuating area.
