FF PO-405 time-delay socket with residual discharge protection 16A, grounded

FF PO-405 time-delay socket with residual discharge protection 16A, grounded is a wall-mounted electrical outlet designed to combine delayed switching and earth-leakage protection in a single unit. The device supplies mains power to connected equipment after a set delay, and includes residual current (leakage) protection to interrupt the circuit if leakage to earth is detected. The grounded design ensures a protective earth connection for compatible plugs and appliances. The socket is rated for continuous current up to 16 A and is intended for domestic and light commercial installations where controlled startup and basic earth-leakage safety are needed.

Advantages

The FF PO-405 integrates time-delay switching with residual current protection, reducing the need for separate components and simplifying installation. Its grounded outlet supports earthed appliances and improves user safety by providing an earth connection. The 16 A rating covers most household appliances and small commercial devices. The compact single-socket format is suitable for replacing or upgrading standard wall outlets while adding timed activation and leakage protection.

Suitable for

• Domestic electrical circuits requiring delayed power-on for appliances
• Light commercial areas where basic earth-leakage protection is desired
• Equipment that benefits from controlled startup to reduce inrush current
• Rooms where a grounded outlet with additional leakage protection is preferred

Key specifications

• Rated current: 16 A
• Function: time-delay switching with residual (earth-leakage) protection
• Connection type: grounded (protective earth)
• Mounting: wall/socket outlet format for standard installation
• Intended use: indoor electrical installations in domestic and light commercial environments

How to use

Install the FF PO-405 in place of a compatible wall socket according to local electrical codes and the installer’s standard procedures. Ensure the supply is isolated before wiring and connect the live, neutral and earth conductors to the corresponding terminals. After correct installation and restoration of supply, the outlet will provide power to connected equipment following the unit’s built-in time-delay sequence and will interrupt power if residual current above the device threshold is detected. Refer to the installer’s documentation for details on delay timing and residual current characteristics.

Usage recommendations

Use the socket with appliances and circuits within the 16 A rating. Have a qualified electrician perform installation and testing to confirm correct earthing and residual leakage operation. Do not expose the unit to outdoor conditions unless it is installed within an appropriately rated enclosure.
