The E-T-A 4230-T110-K0BE-1.2A is a single-pole, thermal-magnetic miniature circuit breaker (MCB) designed for DIN rail mounting. It conforms to standards such as EN 60947-2, UL 1077, and UL 489, offering high rupture capacity.
Key electrical specifications include a current rating of 1.2A and a voltage rating of 277VAC or 60VDC. The breaker features a lever actuator for easy operation and visual status indication. It is built with a positively trip-free snap action mechanism for reliable switching behavior.
Environmental and mechanical specifications include a degree of protection of IP20, an operating ambient temperature range of -35°C to +70°C, and compliance with various IEC testing standards for vibration, shock, corrosion, and humidity. 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. Its robust design and high rupture capacity make it suitable for demanding industrial environments.
The breaker is rated for 277VAC (UL 1077, 1-pole) and 60VDC (UL 1077, 1-pole). Other voltage ratings are available for different standards and pole configurations.
