The E-T-A X4230-FTR335 is a thermal-magnetic miniature circuit breaker accessory, specifically a supply terminal, designed for use with the 4230-T series circuit breakers. It adheres to standards such as EN 60947-2, UL 1077, and UL 489, offering high rupture capacity.
This accessory is suitable for DIN rail mounting and features screw terminals with a maximum tightening torque of 2 Nm. It supports cable cross-sections up to 35 mm² and requires a stripping length of 14 mm. The operating ambient temperature range is from -35°C to +70°C.
Key electrical specifications include a rupture capacity of up to 10,000 A (AC/DC) and various voltage ratings depending on the standard and pole configuration, ranging from 120 VAC to 480Y/277 VAC and 60 VDC to 125 VDC. The mechanical life is rated for 20,000 cycles, and the electrical life for 6,000 cycles.
Environmental and safety features include an overvoltage category of III, impulse withstand voltage of 4kV, and pollution degree 3. The degree of protection is IP20. It has passed tests for vibration, shock, corrosion, and humidity.
The rupture capacity is 10,000 A under UL 489 AC/DC, and 7,500 A AC / 10,000 A DC under IEC/EN 60947-2.
The operating voltage depends on the standard: up to 240 VAC (1-pole IEC), 415 VAC (multi-pole IEC), 277 VAC (1-pole UL 1077), 480Y/277 VAC (multi-pole UL 1077), 120 VAC (1-pole UL 489), 240 VAC (multi-pole UL 489), 60 VDC (1-pole UL), 80 VDC (1-pole IEC), and 125 VDC (2-pole series).
The ambient temperature range is -35°C to +70°C.
It mounts on a DIN rail.
The mechanical life is 20,000 cycles.
The degree of protection is IP20.
