Eaton SPD250480D3K Brand Introduction

Eaton SPD250480D3K is SPD series Type1/Type2 surge protective device developed by Eaton for industrial low voltage power distribution transient overvoltage protection applications. It specializes in clamping lightning surge and switching voltage spikes, serving as rack mount surge suppression assembly for switchgear, MCC and main distribution switchboards.

Surge Protective Device is the core unit of Eaton SPD250480D3K. Surge Protective Device adopts metal shielded housing, 480V delta 3W+G system design, 250kA per phase surge capacity. Surge Protective Device supports 640V L-L and L-G maximum continuous operating voltage, built-in thermal disconnect and surge counter. Surge Protective Device diverts transient surge current to ground to limit residual voltage and protect downstream sensitive electrical equipment.

Eaton SPD250480D3K provides stable Drive for workshop field power system surge protection control. Drive supports continuous 50/60Hz power operation. Drive features UL1449 5th edition certification and internal thermal failure protection. Drive adopts low let-through voltage design and remote dry contact alarm output for fault status monitoring.

Eaton SPD250480D3K features reliable Transmission for upstream main busbar and downstream distribution loads. Transmission communicates via copper power wiring and alarm signal cable. Transmission is fully compatible with Eaton low voltage switchgear and power distribution systems. Transmission absorbs sudden voltage surges and prevents equipment damage caused by lightning or grid switching transients.

Eaton SPD250480D3K is widely used in factory main switchgear, data center power distribution, petrochemical power rooms and legacy power surge protection system renovation. With mature Eaton SPD overvoltage suppression technology, this surge protective device works within temperature range -40~50℃ and has strong anti-vibration and high short-circuit withstand performance. It provides full lifecycle technical support including cabinet installation, wiring commissioning and after-sales maintenance, serving global users as a trusted SPD series 250kA 480V delta surge protective device solution.
