The E-T-A 4230-T120-K0CE-5A is a single-pole thermal-magnetic miniature circuit breaker (MCB) designed for DIN rail mounting. It features toggle actuation, visual status indication, and high rupture capacity, adhering to EN 60947-2, UL 1077, and UL 489 standards.
This circuit breaker has a current rating of 5A and can handle voltage ratings of up to 480VAC or 125VDC, depending on the specific configuration and standard applied. It is suitable for protecting cables, motors, generators, transformers, thyristors, silicon rectifiers, computers, industrial process control systems, telecommunications equipment, and power supplies.
Key technical specifications include a rupture capacity of up to 10,000 A (AC/DC) to UL 489 and IEC/EN 60947-2 (Icu). It operates within an ambient temperature range of -35°C to +70°C and features screw terminals for connection. The device has a mechanical life of 20,000 cycles and an electrical life of 6,000 cycles.
Designed for industrial applications, the 4230-T series offers a positively trip-free snap action mechanism for reliable switching. Its compact design and DIN rail mounting make it easy to integrate into control panels and electrical enclosures.
For 2-pole operation: AC 415 V (IEC/EN 60947-2), AC 240 V or 480Y/277 V (UL 489), and DC 125 V (IEC/EN 60947-2 and UL 489).
