The E-T-A 4230-T130-K0DE-8A is a single and multipole thermal-magnetic miniature circuit breaker (MCB) compliant with EN 60947-2, UL 1077, and UL 489 standards. It is designed for DIN rail mounting and features toggle actuation with visual status indication and high rupture capacity.
Key electrical specifications include a nominal current rating of 8A and voltage ratings up to 480VAC or 125VDC, depending on the standard and pole configuration. The breaker boasts a high rupture capacity of 10,000 A (AC/DC) to UL 489 and IEC/EN 60947-2 (Icu), and 7,500 A (AC) to IEC/EN 60947-2 (Ics).
Mechanical features include screw terminals with a maximum tightening torque of 2 Nm and support for cable cross-sections up to 35 mm². The device operates reliably within an ambient temperature range of -35°C to +70°C. It has a mechanical life of 20,000 cycles and an electrical life of 6,000 cycles.
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 operation at up to 480Y/277 VAC (UL 489/1077) and 125 VDC (2-pole series, UL 489/1077, IEC 60947-2). Additional ratings include 240 VAC under IEC/EN 60947-2 and 80 VDC single-pole.
The circuit breaker mounts on standard DIN rail with screw terminals.
The ambient operating temperature range is -35°C to +70°C.
The interrupting capacity is 10 kA under IEC/EN 60947-2 (Icu AC/DC) and UL 489 AC/DC, and 7.5 kA AC under IEC/EN 60947-2 (Ics).
It is certified to CSA C22.2 No 235, UL 1077, UL 489, and TÜV.
It is a 3-pole circuit breaker.
The breaker is rated for 8A continuous current.
