Sea Side Aquatics Power Relay Switch – RDF (25 Amp)

About This Product

The Sea Side Aquatics Power Relay Switch – RDF is a heavy-duty electrical switching accessory designed for pump-fed Rotary Drum Filter (RDF) systems using high-amperage water pumps. Engineered to accommodate pumps that exceed the standard 10-amp controller limit, this power relay switch supports hardwired pump connections rated up to 25 amps.

Rotary Drum Filters provide efficient mechanical filtration for koi ponds and ornamental water gardens by automatically removing suspended debris, fish waste, and other particles from circulating pond water. In pump-fed installations, reliable pump control is essential for coordinating water movement with the filtration system’s operation.

The Sea Side Aquatics Power Relay Switch provides a solution for pond filtration installations that require larger pumps than a standard RDF controller output can directly accommodate. By using a separate switching device for the higher-current pump circuit, appropriately configured systems can control larger pumps without routing their full operating current through a lower-rated controller output.

Designed specifically for pump-fed RDF applications, this accessory allows a compatible water pump drawing up to 25 amps to be hardwired into the switching system. This makes it particularly useful for large koi ponds, high-flow filtration systems, and installations requiring powerful external or submersible water pumps.

Whether you’re upgrading an existing pump-fed filtration system or installing an RDF with a larger circulation pump, the Sea Side Aquatics Power Relay Switch offers a practical solution for managing higher electrical loads.

Features:

• Designed for pump-fed RDF systems using larger water circulation pumps.
• Supports high-amperage pumps with a manufacturer-advertised switching capacity of up to 25 amps.
• Ideal for pumps exceeding 10 amps that cannot be connected directly to a lower-rated RDF controller output.
• Hardwired pump connection provides an electrical switching solution for compatible high-current installations.
• Supports large pond filtration systems where higher-capacity water pumps are required.
• Separates pump power switching from controller circuitry when installed with a compatible control arrangement.
• Useful for RDF system upgrades when replacing a smaller circulation pump with a higher-amperage model.
• Supports automatic pump control when connected to a suitable RDF controller and correctly configured.
• Suitable for external or submersible pond pumps that meet the electrical requirements of the switching device.
• Designed for koi pond applications using pump-fed mechanical drum filtration.
• Provides additional installation flexibility for larger pond circulation and filtration systems.
• Dedicated RDF accessory offered by Sea Side Aquatics for high-amperage pump applications.

Installation and Maintenance Recommendations:

The Sea Side Aquatics Power Relay Switch should be installed by a qualified electrician familiar with pond equipment, electrical switching devices, and motor circuits.

Before installation, verify the pump’s operating voltage, running amperage, startup current, and electrical protection requirements. Confirm that the relay switch and associated control equipment are appropriately rated for the application.

Disconnect electrical power before beginning installation. Follow the manufacturer’s wiring instructions and applicable electrical codes when connecting the RDF controller, switching device, and water pump.

For outdoor pond applications, provide suitable protection from rain, moisture, and accidental water contact. Use properly rated wiring, circuit protection, grounding, and GFCI protection as required.

After installation, test the switching system to confirm that the pump responds correctly to the RDF controller’s operating commands.

Periodically inspect electrical connections and the protective enclosure for signs of moisture, corrosion, overheating, or damage.

Important Compatibility Information:

This relay switch is intended for pump-fed RDF systems using water pumps that draw more than 10 amps, with a maximum advertised pump current of 25 amps.

The 25-amp rating should not be assumed to apply to every motor type or electrical voltage. Motor starting currents can significantly exceed normal running current, so the complete electrical specifications must be confirmed before installation.

The product is an electrical switching accessory, not a water pump, RDF controller, or complete Rotary Drum Filter.

Recommended application: High-amperage pump switching for large koi ponds, ornamental water gardens, and pump-fed Sea Side Aquatics Rotary Drum Filter installations requiring water pumps beyond a standard 10-amp controller output.
