The E-T-A 4230-T120-K0DE-2A is a thermal-magnetic miniature circuit breaker designed for reliable circuit protection. It operates with a 2A current rating and is configured as a 2-pole device.
This circuit breaker offers versatile voltage ratings, supporting up to 480VAC or 125VDC, and complies with standards such as IEC/EN 60947-2, UL 1077, and UL 489. It features a high rupture capacity of 10,000A (AC/DC) for enhanced safety.
The device is designed for DIN rail mounting, making installation straightforward in control panels and enclosures. Its thermal-magnetic tripping mechanism ensures protection against overloads and short circuits, suitable for protecting cables, motors, and power supplies in industrial process control systems and telecommunications equipment.
The operating voltage depends on the standard and pole configuration. For UL 489, 2-pole AC rating is 240V or 480Y/277V; 1-pole AC is 120V or 277V. For DC, 2-pole series is 125V. For IEC/EN 60947-2, 2,3,4-pole AC is 415V; 1-pole AC is 240V; DC up to 125V.
The ambient temperature range is -35°C to +70°C.
The breaking capacity is 10,000 A (Icu) for AC/DC, 7,500 A (Ics) for AC, and 10,000 A (Ics) for DC.
The breaker is approved to CSA C22.2 No 235 and UL 489. It also meets UL 1077 and IEC/EN 60947-2.
The mechanical life is 20,000 cycles.
The electrical life is 6,000 cycles.
The breaker mounts on a DIN rail.
