The E-T-A 4230-T130-K0BE-25A is a thermal-magnetic miniature circuit breaker (MCB) designed for reliable circuit protection. It features a 25A current rating and a 480VAC/125VDC voltage rating, suitable for various applications.
This 3-pole breaker is designed for DIN rail mounting, ensuring easy integration into electrical panels. It provides a high rupture capacity according to IEC/EN 60947-2 and UL 489 standards, offering robust protection against overcurrents.
Key specifications include a mechanical life of 20,000 cycles and an electrical life of 6,000 cycles. The operating ambient temperature range is -35°C to +70°C, making it suitable for diverse environmental conditions. The terminals are screw type with a maximum tightening torque of 2 Nm.
Typical applications include the protection of cables, motors, generators, transformers, thyristors, silicon rectifiers, computers, industrial process control systems, telecommunications equipment, and power supplies. Its thermal-magnetic tripping mechanism ensures dependable switching behavior.
The voltage rating depends on the standard and pole configuration. For IEC/EN 60947-2: AC 240V (1-pole), AC 415V (2-4 pole), DC 80V (1-pole), DC 125V (2-pole in series). For UL 489: AC 120V (1-pole), AC 240V (2-3 pole), AC 277V (1-pole), AC 480Y/277V (2-3 pole), DC 60V (1-pole), DC 125V (2-pole in series).
The interrupting capacity is 10,000 A per UL 489 and IEC 60947-2 (Icu), and 7,500 A AC per IEC 60947-2 (Ics).
