Model Number: XPFL-I-B25-1 Key Specifications/Special Features: 1.IntroductionXPFL modular power supply surge protective device series, short for XPFL modular power supply SPD, is designed according to the IEC1312-1, IEC61643-1:1998 and GB18802.1-2002 standard, with ability of offering transient overvoltage protection to wires based on 220V/380V low voltage distribution system of buildings. It is employed to prevent equipment damage, fire disaster, explosion and personal inquiry occurs due to lightning overvoltage and transient overvoltage.Main characteristics are:-With temperature control breaker and built-in overvoltage protection circuit to avoid fire hazard completely;-With window indicator to tell operation condition and fault condition, clearly and directly;-Easy installation and maintenance;-Good quality. Giving a consistent and reliable performance under tough environment such as acid, alkali, dust, salt spray and humid.2. Features
XPFL modular power supply SPD series, window indicator of each single modular shows operation condition of corresponding phase separately. When indicator shows in green, it means normal. When it turns to red, it means surge protective device is in fault.
