The E-T-A 4230-T110-K0DE-50A is a thermal-magnetic miniature circuit breaker (MCB) designed for reliable circuit protection. It features a single pole configuration and is suitable for DIN rail mounting.
This breaker has a current rating of 50A and can handle voltages up to 277VAC or 60VDC. It is built in accordance with EN 60947-2, UL 1077, and UL 489 standards, ensuring robust performance.
Key specifications include a high rupture capacity of 10,000A AC/DC, an operating ambient temperature range of -35°C to +70°C, and screw terminals for secure connections. The breaker also meets stringent environmental testing standards for vibration, shock, corrosion, and humidity.
Typical applications include the protection of cables, motors, generators, transformers, thyristors, silicon rectifiers, computers, industrial process control systems, telecommunications equipment, and power supplies.
The voltage rating depends on the standard: for UL 1077 it is 277VAC/60VDC; for UL 489 it is 240VAC/125VDC; for IEC/EN 60947-2 it is 415VAC/80VDC.
