The E-T-A 1180-01-0.3A is a thermal circuit breaker in a very compact design, suitable for replacing conventional fuses in equipment operating on AC and DC voltage ranges. It offers reliable switching behavior with snap action and positively trip-free mechanisms. The plug-in design is ideal for standard terminal blocks on DIN rail mounting, making installation easy.
This circuit breaker features a current rating of 300mA and a voltage rating of 250VAC or 65VDC. Its very small width of only 8.2 mm saves space in control cabinets and process control systems. The push-push button allows for direct switching off of the load for maintenance purposes, preventing device loss as it remains within the terminal block.
Key features include its universally suitable AC and DC applications, fine grading of current ratings, and increased system availability due to its reset option. The device meets the requirements of the EN 60934 (IEC 60934) circuit breaker standard (S-Type, TO).
Typical applications include the protection of loads in power distribution systems within control cabinets and process control environments. Accessories like bridging connectors and jumpers are available for simplified LINE and GND wiring.
