The E-T-A 3131-AF1NT-000000-1T2-20A is a single-pole thermal circuit breaker designed for overcurrent protection in demanding environments. It is rated for 20A continuous current at 240V AC and 28V DC, with interrupting capacities up to 3000A (UL1077) and 10xIN (IEC). The breaker features a resettable thermal mechanism and requires a separate actuator (not included).
Environmental robustness is assured by an IP66 rated operating area, allowing use in dusty, wet, and corrosive conditions. The device withstands vibration of 5g (57-500 Hz), shock of 25g (11 ms), corrosion for 96 hours at 5% salt mist, and humidity for 240 hours at 95% RH. Operating temperature spans -20°C to +60°C.
Illumination is optional with a blue LED (10~14V) available. The breaker carries approvals IEC 60934, UL1077, and UL1500, making it suitable for marine, industrial, and transportation applications. Mechanical endurance exceeds 30,000 operations at rated current inductive load.
Mounting is panel mount with a compact mass of approximately 30g. The 3131 series modules integrate easily into control cabinets and distribution panels requiring reliable thermal protection.
