Why Choose the Finder 99.80.8.230.07 Residual Current Bypass Module?
The Finder 99.80.8.230.07 is a compact and reliable residual current bypass resistor module designed to prevent unwanted relay operation caused by leakage currents in AC control circuits. As part of the Finder Series 99 relay accessories range, this plug-in function module provides an effective solution for suppressing residual currents that can prevent relay coils from fully de-energising in industrial automation, electrical control panels and building control systems.
The module incorporates a bypass resistance that provides an alternative path for unwanted residual current in the relay coil circuit. This helps prevent unintended relay energisation, delayed release and unreliable switching caused by leakage currents from electronic control devices. Its compact plug-in construction simplifies installation into compatible Finder relay sockets without requiring a separately wired external bypass resistor.
Designed for 110–240 V AC control circuits, the Finder 99.80.8.230.07 is suitable for applications using electronic switching devices, PLC outputs and other control equipment where small leakage currents may remain present when the output is switched off. Its socket-mounted design makes it particularly useful in industrial control cabinets, automation systems and electrical installations requiring dependable relay operation.

Reliable Residual Current Suppression for AC Relay Control Systems
Electronic switching devices such as solid-state outputs, semiconductor switches and certain PLC output circuits may allow a small amount of leakage current to flow even when their outputs are switched off. In some relay installations, this residual current can maintain sufficient voltage across the relay coil to cause unreliable release, unwanted energisation or other switching problems. The Finder 99.80.8.230.07 provides a bypass resistance that diverts residual current away from the relay coil, helping ensure that the relay returns to its intended de-energised state.
The Finder Series 99 residual current bypass module is designed for integration into compatible relay sockets, providing a convenient solution without additional external resistor wiring. Its 110–240 V AC operating range makes it suitable for a variety of AC relay control systems. Unlike diode or varistor modules primarily intended to suppress inductive switching transients, this module specifically addresses unwanted residual current in the relay control circuit. Correct socket selection and circuit compatibility should be confirmed before installation.
