The E-T-A 4230-T110-K0DU-15A is a single-pole, thermal-magnetic miniature circuit breaker (MCB) designed for reliable protection in various applications. It conforms to EN 60947-2, UL 1077, and UL 489 standards.
Key electrical specifications include a 15A current rating and multiple voltage ratings such as 277VAC and 60VDC, with higher AC ratings available for multi-pole configurations. It boasts a high rupture capacity of up to 10,000A (AC/DC) according to UL 489 and IEC/EN 60947-2 standards.
This circuit breaker features DIN rail mounting for easy installation and screw terminals for secure connections. It operates within an ambient temperature range of -35°C to +70°C and offers a mechanical life of 20,000 cycles and an electrical life of 6,000 cycles.
Typical applications 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 AC 277V (1-pole, UL 1077) and DC 60V (1-pole, UL 1077). It also supports AC 120V (1-pole, UL 489) and AC 240V (2, 3-pole, UL 489).
The current rating is 15A, within the range of 1A to 63A for most configurations, and 1A to 32A for UL 489 at 277VAC.
The rupture capacity is 10,000A under UL 489 and IEC/EN 60947-2 (Icu) for both AC and DC. Under IEC/EN 60947-2 (Ics), it is 7,500A AC and 10,000A DC.
The ambient temperature range is -35°C to +70°C.
The breaker is designed for DIN rail mounting.
The degree of protection is IP20.
The breaker uses screw terminals with a maximum tightening torque of 2 Nm and a stripping length of 14 mm. It accepts cable cross sections up to 35 mm².
