The E-T-A 1180-02-1A is a thermal circuit breaker in a compact design, suitable as a replacement for conventional fuses in both AC and DC voltage ranges. It offers reliable switching behavior with snap action and positively trip-free mechanisms. The reset option significantly increases system availability compared to traditional fuses.
This plug-in type device is designed for standard terminal blocks and DIN rail mounting, making installation easy. For maintenance, the load can be switched off directly at the circuit breaker using the push-push button, preventing device loss as it remains in the terminal block. Accessories like bridging connectors are available for simplified wiring.
Key electrical specifications include a voltage rating of 250V AC and 65V DC (72V DC for UL/UL Canada). It has a current rating of 1A and a thermal breaker type. The device operates within an ambient temperature range of -20°C to +60°C.
The 1180 series meets EN 60934 (IEC 60934) standards and is suitable for protecting loads in power distribution systems, control cabinets, and process control applications. Its very small width of only 8.2 mm saves space in equipment.
The breaker is rated for 250VAC (UL, UL Canada), 72VDC (UL, UL Canada), and 65VDC general.
The ambient temperature range is -20 to +60°C.
The breaker is designed for holder mounting.
The rated current is 1A, with a series range of 0.1 to 10A.
It is a single-pole (1-pole) circuit breaker.
The actuator is push-push (push to trip, push to reset).
Typical life is 6,000 operations at 1xIn low-inductance, 3,000 operations at 1xIn inductive, and 500 operations at 2xIn inductive.
