The E-T-A 4230-T110-K0CE-50A is a single-pole, thermal-magnetic miniature circuit breaker (MCB) designed for reliable circuit protection. It features a current rating of 50A and supports a voltage rating of 277V AC or 60V DC.
This circuit breaker conforms to EN 60947-2, UL 1077, and UL 489 standards, offering a rupture capacity of up to 10,000A. It is built with a positively trip-free snap action mechanism for dependable switching behavior.
The device is suitable for DIN rail mounting, making installation straightforward in control panels and enclosures. Its robust construction ensures operation within an ambient temperature range of -35°C to +70°C. Typical applications include protection of cables, motors, generators, transformers, and electronic equipment like computers and telecommunication systems.
Key specifications include a mechanical life of 20,000 cycles and an electrical life of 6,000 cycles. The terminals are screw-type, with a maximum tightening torque of 2 Nm and a stripping length of 14 mm, accommodating cable cross-sections up to 35 mm².
The breaker is rated for multiple voltage ranges depending on the standard: 277V AC (UL 1077), 480Y/277V AC (UL 1077/489), 120-240V AC (UL 489), 240-415V AC (IEC/EN 60947-2), and up to 125V DC.
It is designed for DIN Rail mounting.
