The E-T-A 1180-02-0.4A is a compact thermal overcurrent circuit breaker designed as a replacement for conventional fuses in AC and DC voltage equipment. It offers reliable switching behavior with a snap-action, positively trip-free mechanism. The plug-in design allows for easy mounting on standard terminal blocks for DIN rail mounting, preventing device loss during maintenance.
Key electrical specifications include a voltage rating of 250 VAC and 65 VDC (72 VDC for UL/UL Canada). This model features a current rating of 400mA and a single pole configuration. The breaker type is thermal, with a push-push actuator for manual switching.
With a very small width of only 8.2 mm, the 1180 series saves space and weight in equipment. It is suitable for applications in power distribution systems, control cabinets, and process control. The reset option increases system availability compared to traditional fuses.
The circuit breaker meets the requirements of the EN 60934 (IEC 60934) standard. It has a typical operating life of 6,000 operations at 1x In (low-inductance) and 3,000 operations at 1x In (inductive). The operating temperature range is -20°C to +60°C.
The voltage rating is 250 VAC and 72 VDC (UL, UL Canada).
The current rating is 400mA (0.4 A).
It is a thermal circuit breaker.
