The E-T-A 3131 Series thermal circuit breaker combines a single-pole circuit breaker with an ON/OFF switch, featuring a soft-touch rocker actuation. This device is sealed to provide IP66 rated front of panel water splash protection, making it suitable for demanding environments. It meets the requirements of circuit breaker standard EN 60934 (IEC 60934).
Key electrical specifications include a voltage rating of 240V AC / 28V DC and a current rating range from 0.1A to 20A. The interrupting capacity is rated at 10 x IN for currents up to 2A and 200A for currents from 2.5A to 20A. It also meets UL 1077 interrupting capacity ratings of 3,000A AC and 2,500A DC.
Designed for a wide range of applications, including motor protection, transformer protection, household appliances, electrical tools, and mobile homes, the 3131 series offers reliable circuit protection. The operating temperature range is -20°C to +60°C. The unit has a typical life of 30,000 operations at 1 x IN, inductive.
Mounting is via a panel mount design. The device features optional illumination with a nominal voltage of 20-32V and a power consumption of 10mA at 12V/24V. The terminal area has an IP00 protection class.
