The E-T-A 1180-01-0.4A is a thermal overcurrent circuit breaker in a very compact design, suitable for replacing conventional fuses in AC and DC voltage ranges. It offers reliable switching behavior with snap action and a positively trip-free mechanism. The plug-in design allows for easy mounting on standard terminal blocks for DIN rail mounting.
Key features include a narrow width of only 8.2 mm, making it space-saving. The breaker is universally suitable for both AC and DC applications, with a voltage rating of 250 VAC and 65 VDC (72 VDC for UL/UL Canada). The current rating is 400mA.
For maintenance, the load can be switched off directly via a push-push button, preventing device loss as it remains in the terminal block. Accessories like bridging connectors are available for wiring. This circuit breaker meets the requirements of the EN 60934 (IEC 60934) standard.
Typical applications include the protection of loads in power distribution systems within control cabinets and process control systems. Its reset option significantly increases system availability compared to conventional fuses.
