The E-T-A 3131-AF1PT-000000-1T3-20A is a versatile single-pole thermal circuit breaker that also functions as an ON/OFF switch. It features a soft-touch rocker actuation and is sealed to provide IP66 rated front-of-panel water splash protection.
This circuit breaker meets the requirements of EN 60934 (IEC 60934) standards. It has a voltage rating of 240 VAC and 28 VDC, with a current rating range from 0.1 to 20 A. The typical life is 30,000 operations at 1 x IN, inductive. It operates within an ambient temperature range of -20 to +60 °C.
Typical applications include motor protection, transformer protection, household appliances, office equipment, electrical tools, mobile homes, watercraft, construction vehicles, and medical equipment. The device is designed for panel mounting and offers optional illumination in blue.
Key technical data includes an interrupting capacity of 10 x IN for lower current ratings and 200 A for higher ratings (2.5-20 A). It also meets UL 1077 standards with an interrupting capacity of 3,000 A at 240 VAC and 2,500 A at 32 VDC. The operating area is IP66 protected, while the terminal area is IP00.
The circuit breaker is rated for 240 VAC and 28 VDC.
The operating temperature range is -20 to +60 °C.
It is designed for panel mounting.
For currents 0.1...2 A, the interrupting capacity is 10 x IN. For 2.5...20 A, it is 200 A. UL 1077 ratings for 0.1...16 A are 3,000 A at 240 VAC and 2,500 A at 32 VDC.
The typical life is 30,000 operations at 1 x IN, inductive load.
Insulation coordination is 2.5 kV/2 per IEC 60664. Dielectric strength is AC 3,000 V across the operating area and AC 1,500 V between current paths.
