Description:

Cooper Wheelock’s Explosion Proof Relays are precision built

of extremely rugged materils for long, trouble-free life in hazard-

ous and diffi cult enviornmentjs. Designed primarily for telephone

systems, they sense low voltage AC or DC and switch 115 and

220 volts AC at 60 Hz or 115 volts DC with contact arrangement;

single-pole, normally open, double A (double make in parallel).

The XRT-T-40 has a 0.45 microfared blocking capacitor in series

with the coil and a one megohm resistor across the capacitor.

The XRT-T-40 is FCC registered.

The XRT Explosion Proof Relay is designed to switch high (115

or 220) voltage using low voltage, such as ringing current in

telephone systems, as the controlling voltage. These units can

switch devices controlled by low current controlling systems.

The units are easy to handle and install, and provide convenient

access to coil and contact terminals.
