The E-T-A 4230-T130-K0BE-1.5A is a thermal-magnetic miniature circuit breaker (MCB) designed for reliable circuit protection. It conforms to EN 60947-2, UL 1077, and UL 489 standards.
This 3-pole breaker has a current rating of 1.5A and can operate at up to 480V AC or 125V DC. It features a lever actuator and is designed for DIN rail mounting, making installation straightforward in control panels and industrial equipment.
Key technical specifications include a rupture capacity of 10,000 A (AC/DC) to UL 489 and IEC/EN 60947-2 (Icu), an impulse withstand voltage of 4kV, and a pollution degree of 3. The operating ambient temperature range is -35°C to +70°C.
Typical applications include protection of cables, motors, generators, transformers, thyristors, silicon rectifiers, computers, industrial process control systems, telecommunications equipment, and power supplies.
The operating voltage depends on the standard: up to 480VAC (IEC/EN 60947-2, UL 1077, UL 489) and up to 125VDC (IEC/EN 60947-2, UL 489) with specific pole configurations.
The ambient temperature range is -35°C to +70°C.
Rupture capacity is 10,000 A AC/DC under UL 489 and IEC/EN 60947-2 Icu, and 7,500 A under Ics (IEC/EN 60947-2).
It is a 3-pole device.
DIN rail mounting.
Screw terminals with a maximum tightening torque of 2 Nm and stripping length of 14 mm.
The nominal current rating is 1.5A, but the device supports a range from 1A to 63A depending on configuration and standard.
