This E-T-A 1170-22-30A is a single-pole thermal circuit breaker designed for reliable protection in extra-low voltage wiring systems found in vehicles and marine craft. It incorporates a tease-free, trip-free, snap-action mechanism with a push-to-reset actuator and a separate manual release.
The breaker is rated for 30A current and supports voltage ratings of 12V, 24V, and 48VDC, with a maximum operating voltage of 58VDC. It meets Type III requirements per SAE J 553.
Fitted with blade terminals for plug-in mounting into automotive fuse blocks, this circuit breaker offers convenience and a low cost of ownership. Its robust construction is tested for vibration, shock, corrosion, and humidity, making it suitable for demanding environments. The operating temperature range is -40°C to 85°C.
Key technical data includes an interrupting capacity of ≥ 2000A and typical life cycles ranging from 500 to 6000 operations depending on the current load.
The current rating is 30A.
It supports DC voltage ratings of 12V, 24V, and 48V.
It features a push-to-reset actuator.
The operating temperature range is -40°C to 85°C.
