Lightning Surge Protectors for

Electronics Equipment M-RESTER

LIGHTNING SURGE PROTECTOR FOR RTD USE

Functions & Features

• Designed specifically for resistance temperature detector

(RTD) circuits

• Protecting RTD and RTD transmitters from damage caused

by surges on the RTD wiring

• Absorbs surges only without affecting instrumentation

signal

• No interruption of signal by unplugging the protector

element
