The E-T-A X4230-TC3 is a protection contact accessory specifically designed for use with the 4230-T series circuit breakers. It provides a compact and reliable interface for monitoring and controlling circuit protection in industrial and commercial applications.
Key electrical specifications include multiple voltage ratings depending on the standard and pole configuration: under IEC/EN 60947-2, 1-pole AC 240 V, 2-4 pole AC 415 V; DC 80 V (1-pole) and 125 V (2-pole). Under UL 1077, 1-pole AC 277 V, multi-pole AC 480Y/277 V; DC 60 V (1-pole) and 125 V (2-pole). Under UL 489, 1-pole AC 120 V or 277 V, multi-pole AC 240 V or 480Y/277 V; DC 60 V (1-pole) and 125 V (2-pole). Rupture capacity is 7,500 A (Ics) and 10,000 A (Icu) per IEC/EN 60947-2, and 10,000 A per UL 489.
Mechanical design features include screw terminals with a maximum tightening torque of 2 Nm, stripping length of 14 mm, and cable cross-section up to 35 mm². The unit is DIN rail mountable and has a protection degree of IP20. Mass is approximately 116 g per pole under EN 60947-2 / UL 1077 and 131 g per pole under UL 489. Environmental endurance includes vibration (IEC 60068-2-6), shock (30 g), corrosion (96 hr salt mist), and humidity (48 hr at 95% RH, 40°C) testing. Operating ambient temperature range is -35°C to +70°C. Mechanical life is 20,000 cycles and electrical life is 6,000 cycles.
The voltage rating varies by standard and pole configuration, ranging from AC 120 V to 480Y/277 V and DC 60 V to 125 V.
