The E-T-A 1160-02-12A is a single-pole, thermal circuit breaker designed for automotive and marine extra low voltage applications. It operates at 12VDC and has a current rating of 12A.
This circuit breaker features a controlled self-resetting mechanism, making it suitable for installation in inaccessible locations. Under overload conditions, the contacts open to protect the load circuit. A low current excitation circuit ensures the contacts remain open, preventing hazardous automatic reset operations. The breaker resets by switching off the supply circuit for a short period. It is classified as a Class 2 device, where contacts stay open until voltage is removed.
Key technical data includes a holding current of less than 0.6A, a reset time of less than 35 seconds at 23°C, and an interrupting capacity of 200A at L/R = 2.5 ms. The housing offers IP54 degree of protection, while the terminal area is IP00.
Environmental testing includes vibration resistance up to 5g, shock resistance up to 25g, 96 hours of corrosion resistance, and 240 hours of humidity resistance. The operating temperature range is -30°C to +60°C. The approximate mass of the unit is 6g.
The operating voltage is 12 VDC.
It mounts using a holder.
