The E-T-A 4230-T110-K0BE-12A is a thermal magnetic miniature circuit breaker (MCB) designed for DIN rail mounting. It conforms to EN 60947-2, UL 1077, and UL 489 standards.
This single-pole breaker has a current rating of 1.2A and can handle AC voltages up to 277V and DC voltages up to 60V. It features a lever actuator and no illumination. The breaker offers a rupture capacity of 10,000 A (AC/DC) to UL 489 and 7,500 A (AC) / 10,000 A (DC) to IEC/EN 60947-2.
Key specifications include a mechanical life of 20,000 cycles and an electrical life of 6,000 cycles. It operates within an ambient temperature range of -35°C to +70°C. The terminals are screw type, supporting cable cross-sections up to 35 mm² with a maximum tightening torque of 2 Nm.
Typical applications for this circuit breaker include the protection of cables, motors, generators, transformers, thyristors, silicon rectifiers, computers, industrial process control systems, telecommunications equipment, and power supplies.
The breaker is rated for AC 277V (UL 1077), AC 240V (IEC/EN 60947-2), and DC 60V (1-pole). For multi-pole configurations, higher voltages are available.
