Eaton SPM250480Y1R Brand Introduction

Eaton SPM250480Y1R is SPM series Type1/Type2 surge protective device developed by Eaton for industrial low voltage power distribution transient overvoltage protection applications. It specializes in diverting lightning surge and switching voltage spikes to ground, serving as enclosed mount surge suppression assembly for main switchboards, MCC, ATS and critical power distribution panels.

Surge Protective Device is the core unit of Eaton SPM250480Y1R. Surge Protective Device adopts NEMA 1 metal enclosed housing, 480V wye 4W+G system design, 250kA per phase surge capacity. Surge Protective Device is equipped with thermally protected MOV modules, phase LED status indicators and remote dry contact fault alarm output. Surge Protective Device limits residual voltage and protects downstream PLC, variable frequency drives and field instrumentation equipment from transient overvoltage damage.

Eaton SPM250480Y1R provides stable Drive for workshop field power system surge protection control. Drive supports continuous 50/60Hz AC power operation. Drive complies with UL1449 5th edition standard, fitted with internal thermal disconnect safety mechanism. Drive features low let-through voltage characteristic for sensitive loads and easy visual health inspection via front LED lights.

Eaton SPM250480Y1R 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 failure caused by lightning strike or grid switching transients.

Eaton SPM250480Y1R is widely used in factory main power rooms, water treatment control panels, oil & gas auxiliary power and legacy power surge protection system renovation. With mature Eaton SPM 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 SPM series 250kA 480V wye surge protective device solution.
