The E-T-A 4230-T110-K0CE-12A is a single-pole, thermal-magnetic miniature circuit breaker designed for reliable circuit protection. It is compliant with EN 60947-2, UL 1077, and UL 489 standards.
This circuit breaker has a current rating of 12A and can handle voltages up to 277VAC or 60VDC. It offers a high rupture capacity of 10,000A AC/DC according to UL 489 and IEC/EN 60947-2 (Icu). The device is designed for DIN rail mounting and features a lever actuator with visual status indication.
Environmental testing includes vibration resistance to IEC 60068-2-6, shock resistance to IEC 60068-2-27, corrosion resistance to IEC 60068-2-11, and humidity testing to IEC 60068-2-78. The operating ambient temperature range is -35°C to +70°C.
Typical applications include the protection of cables, motors, generators, transformers, thyristors, silicon rectifiers, computers, industrial process control systems, telecommunications equipment, and power supplies. It provides robust protection with a mechanical life of 20,000 cycles and an electrical life of 6,000 cycles.
For 1-pole AC operation, rated 277VAC (UL 1077) or 240VAC (IEC). For DC, 60VDC (1-pole) or 125VDC (2-pole in series).
