The E-T-A 1180-02-4A is a compact thermal overcurrent circuit breaker designed as a replacement for conventional fuses in both AC and DC voltage systems. It offers reliable switching behavior with a snap-action mechanism and a positively trip-free design. The push-push button allows for direct load switching for maintenance purposes, preventing device loss as it remains within the terminal block.
This circuit breaker is suitable for standard terminal blocks and DIN rail mounting, featuring a very small width of only 8.2 mm, saving space and weight in equipment. It is universally applicable for AC and DC circuits, with a voltage rating of 250V AC and 72V DC, and a current rating of 4A. The device meets the requirements of the EN 60934 (IEC 60934) circuit breaker standard.
Key benefits include increased system availability through its reset option, quick troubleshooting capabilities, and reduced maintenance costs. Accessories such as bridging connectors and jumpers are available for easy wiring. The 1180 series offers fine grading of current ratings, particularly in the range of small ratings, making it a versatile protection solution for power distribution systems in control cabinets and process control applications.
It is rated for 250V AC and 72V DC operation.
The current rating is 4A.
The operating temperature range is -20°C to +60°C.
Up to 6,000 operations at rated current under low-inductance conditions.
It is a thermal, 1-pole, push-push actuator circuit breaker.
It is designed for holder mounting.
