Why Choose the Chint S9-1 Shunt Release?
The Chint S9-1 is a compact and reliable shunt release accessory designed to remotely trip compatible Chint miniature circuit breakers and RCBOs when a control voltage is applied. It is used where electrical circuits need to be opened from a remote switch, control relay, emergency stop circuit or automation system.
Designed for use with compatible Chint NB1, NBH8, NB1L and NBH8LE series protective devices, the S9-1 mounts to the left-hand side of the breaker using a dedicated pin connection. This makes it a practical accessory for distribution boards, control panels and switchboards requiring remote disconnection functionality.
With a rated control voltage suitable for AC 230/400 V applications, the S9-1 provides dependable remote tripping performance while maintaining a compact DIN rail accessory format. It is ideal for safety circuits, building services panels and industrial electrical systems where fast remote circuit isolation is required.
