Eaton - SPDT3

The Eaton SPDT3 series is built for electricians who need dependable surge protection without the guesswork. Designed as modular equipment, these devices fit seamlessly into standard distribution boards and modern electrical panels. Whether you are wiring a new home, upgrading a commercial building, or maintaining an industrial site, the SPDT3 series gives you a straightforward solution to guard sensitive electronics and wiring against dangerous voltage spikes.

Simple Setup and DIN Rail Compatibility

Installers know that time on the job matters. The SPDT3 series is engineered for quick, tool-friendly mounting on standard DIN rails. The modular design means you can mix and match components to fit your panel layout without custom fabrication. Clear terminal markings and straightforward wiring diagrams reduce setup errors, so you can finish the job faster and move on to the next task with confidence.

SPDT3-335-1+NPE: Targeted Protection Where It Counts

The SPDT3-335-1+NPE surge protective device is a standout in the lineup. This unit is built to clamp high-energy transients and safely divert them to ground, protecting your circuits from lightning strikes, grid switching, and equipment faults. The 1+NPE configuration works perfectly with single-phase systems and neutral-to-earth grounding setups. Its robust clamping voltage and high discharge capacity mean your downstream devices stay safe even during severe surges.

Clear Status Indicators and Thermal Safety

Maintenance should never be a mystery. Each SPDT3 device features visible status indicators that instantly show whether the protection is active or if the unit needs replacement. Built-in thermal protection automatically disconnects the device if it overheats, preventing fire hazards and keeping your installation code-compliant. This proactive safety layer gives you peace of mind and reduces callback visits for troubleshooting.

Trusted Engineering for Every Electrical Job

Eaton has a long history of delivering reliable electrical components, and the SPDT3 series continues that tradition. From residential panels to light commercial applications, these surge protectors offer consistent performance, easy replacement, and long service life. When you specify the SPDT3 series, you are choosing a modular equipment line that simplifies your workflow, protects your customers’ investments, and meets the demands of modern electrical standards.
