The Chint XF9 is a compact and reliable auxiliary contact accessory designed to provide remote status indication for compatible Chint miniature circuit breakers and RCBOs. It is used to signal the ON, OFF or tripped position of a connected protective device, helping improve monitoring and control within low voltage electrical distribution systems.
Designed for use with compatible Chint NB1, NBH8, NB1L and NBH8LE devices, the XF9 mounts to the left side of the circuit breaker or RCBO using a dedicated connection pin. Its 1 normally open and 1 normally closed contact configuration allows it to integrate easily into signalling, indication and control circuits.
With a rated insulation voltage of 500 V and contact ratings suitable for AC and DC control circuits, the XF9 is ideal for distribution boards, control panels, switchboards and automation systems where clear electrical status feedback is required.
Key Advantages
Compact auxiliary contact for Chint MCBs and RCBOs.
Provides remote indication of ON, OFF or tripped status.
Compatible with selected NB1, NBH8, NB1L and NBH8LE series devices.
Suitable for AC and DC control, monitoring and indication applications.
DIN rail device accessory designed for neat panel integration.
Key Features
Chint XF9 auxiliary contact accessory.
1 normally open and 1 normally closed contact.
Rated insulation voltage of 500 V.
Rated impulse withstand voltage of 4 kV.
Mounts to the left side of compatible MCBs and RCBOs.
Provides electrical status feedback for monitoring circuits.
Suitable for residential, commercial and industrial distribution panels.
Compliant with IEC/EN 60947-5-1.
Reliable Status Feedback for Distribution Systems
Auxiliary contacts such as the Chint XF9 are used to transmit the operating status of a connected circuit protection device to external control, indication or monitoring equipment. This allows electrical panels to provide visual alarms, remote status feedback or system interlocking based on the position of the protective device.
The XF9 is particularly useful in control panels and distribution boards where operators need to know whether a circuit breaker or RCBO is switched ON, switched OFF or has tripped. Its compact design and compatible mounting arrangement make it a practical accessory for professional low voltage installations.
Typical Applications
Distribution board status indication.
Control panel monitoring circuits.
Remote signalling for MCBs and RCBOs.
Building services electrical panels.
Industrial switchboards and machine panels.
Alarm, indication and automation control circuits.
