The E-T-A 3131 Series is a combination thermal circuit breaker and ON/OFF switch designed for reliable circuit protection. This model, the 3131-AF1NT-000000-1Y7-5A, features a 5A current rating and can handle up to 240 VAC or 28 VDC.
It meets the requirements of circuit breaker standard EN 60934 (IEC 60934). The front of the panel is sealed to provide IP66 rated water splash protection, making it suitable for demanding environments. Typical applications include motor protection, transformer protection, household appliances, electrical tools, and construction vehicles.
This circuit breaker is designed for panel mounting and offers a typical operational life of 30,000 operations at 1 x IN, inductive. The ambient operating temperature range is -20 to +60 °C. It also features optional illumination with a yellow indicator.
Key technical data includes a dielectric strength of AC 3,000 V and an insulation resistance greater than 100 MΩ (DC 500 V). Approvals include IEC 60934, UL1077, and UL1500.
The circuit breaker is rated for 240 VAC and 28 VDC operation.
It is a panel mount device.
The ambient temperature range is -20°C to +60°C (-4°F to +140°F).
The nominal current rating is 5A, with a current range of 0.1 to 20 A.
Interrupting capacity varies: 10 x IN for 0.1-2 A, 200 A for 2.5-20 A, 3000 A at 240 VAC, and 2500 A at 32 VDC.
It is a single-pole (1 pole) circuit breaker.
The breaker features yellow illumination with nominal voltage 185~275V and supports 12V (10mA), 24V (10mA), 115V (<1mA), and 230V (<1mA).
