The E-T-A 1160-02-20A is a thermal circuit breaker with a controlled self-resetting mechanism, suitable for automotive and marine extra-low voltage applications. It features a 12VDC voltage rating and a 20A current rating, with a holding current of less than 0.6A.
This circuit breaker is designed to protect load circuits under overload conditions. Under overload, the contacts open, and a low current excitation circuit ensures they remain open, preventing hazardous automatic reset operations. Resetting is achieved by briefly switching off the supply circuit. The device has a typical life of 300 operations at 2x IN and an interrupting capacity of 200A.
Environmental specifications include an operating temperature range of -30°C to +60°C and a housing area degree of protection of IP54. It has undergone vibration, shock, corrosion, and humidity testing according to IEC standards.
Mounting is via a holder, and the breaker is a single-pole, plug-in type. The E-T-A 1160 series is specifically suited for installation in inaccessible locations within automotive and marine wiring systems, as well as battery-powered appliances.
The voltage rating is 12 VDC.
The current rating is 20 A.
It features an automatic reset mechanism.
The operating temperature range is -30 to +60 °C.
The housing area has a degree of protection of IP54.
