This E-T-A 4230-T130-K0CE-4A is a thermal-magnetic miniature circuit breaker designed for reliable circuit protection. It features a 3-pole configuration with a 4A current rating and a voltage rating of 480VAC or 125VDC.
Constructed in accordance with EN 60947-2, UL 1077, and UL 489 standards, this breaker offers high rupture capacity. It is suitable for DIN rail mounting, making installation straightforward in control panels and electrical enclosures.
Key specifications include a wide ambient temperature range of -35°C to +70°C and a mechanical life of 20,000 cycles. The terminals are screw-type, accommodating cable cross-sections up to 35 mm² with a maximum tightening torque of 2 Nm.
Typical applications include protection of cables, motors, generators, transformers, and electronic equipment in industrial process control systems, telecommunications, and power supplies.
The rated current is 4 A.
The voltage ratings vary by standard: IEC/EN 60947-2: AC 240 V, DC 80 V (or 125 V with 2-pole series); UL 1077: AC 277 V, DC 60 V (125 V 2-pole series); UL 489: AC 120/240/277/480Y/277 V, DC 60 V (125 V 2-pole series).
The ambient temperature range is -35°C to +70°C.
It is DIN rail mounted with screw terminals. Cable cross-section up to 35 mm², stripping length 14 mm, tightening torque 2 Nm.
The rupture capacity (Ics) is 7,500 A AC and 10,000 A DC. The ultimate rupture capacity (Icu) is 10,000 A AC/DC per UL 489.
It is approved under UL 489, UL 1077, CSA C22.2 No. 235 and No. 5, and TÜV IEC/EN 60947-2.
Mechanical life is 20,000 cycles minimum; electrical life is 6,000 cycles minimum.
