Chint XF9 Signal contact: clear indication of device status
The Chint XF9 signalling contact (code 184994) is a useful device for monitoring the status of circuit breakers and residual current devices (MCB/RCBO). The 1NA+1NC configuration allows signalling both the open and closed position of the contacts, providing a precise visual indication of the device's switching status.
Easy installation and compatibility
This signalling contact is easily mounted on the left side of the switches, thanks to a dedicated pin that facilitates installation. It is compatible with series NB1, NBH8, NB1L, NB310L, and allows up to two contacts to be placed side by side for a signalling system on multiple devices.
Performance and reliability
The XF9 contact is designed to withstand voltages up to 500 V and to operate in environments with temperatures ranging from -5°C to +40°C. The insulation voltage is 500V, while the impulse withstand voltage reaches 4 kV (1.2/50 µs), ensuring safe and reliable performance over time. The device complies with international standards, with IP20 protection ratings making it resistant to dust and small water ingress.
Durability and maintenance
With a mechanical life of 10,000 cycles and an electrical life of 6,050 cycles, the Chint XF9 contact is designed to last long, even in high-frequency use applications. Installation and maintenance are simplified thanks to the 2.5 mm² cable connection, with a tightening torque of 0.8 N·m to ensure a secure connection.
