Surge Protection for Outdoor Transformer 04

Basic circuit diagram

Features

REP-MP40/2P adopts UL certified MOV as the key component
Max discharge current Imax(8/20μs) at each path(L-PE;N-PE)
Easy installation, Sealed well for water-proof and inflaming retarding,
Suitable for harsh outdoor environment
Function optional: failure indicator; remote contact monitoring

Application

REP-MP40/2P is installed outdoor at the low-voltage side of transformer to protect the transformer avoiding failure and damage in case of low voltage surge and over voltage occurs.
