CHINT AX-5 Auxiliary Contact,
is an accessory designe for use with the NL1 Residual Current Circuit Breaker (RCCB).
It provides remote ON/OFF signal indication for AC and DC circuits, enhancing system monitoring and control.
Rate at 6A heating current and suitable for AC 415V or DC 130V, the AX-5 ensures reliable operation across diverse low-voltage applications.
Built to IEC 60947-5-1 and GB/T 14048.5 standards,
it offers high durability with over 10,000 operating cycles,
compact design, and straightforward DIN-rail mounting.
