The PL Series Phase Monitor Relays provide protection against phase loss & phase reversal in a compact plug-in design. These devices are designed to be compatible with most Wye or Delta systems. In Wye systems, a connection to a neutral is not required. Phase Monitor Relays protect against single phasing regardless of any regenerative voltages.

The relay is energized and the LED on when all three phases are present and in the correct sequence. Any fault will instantaneously de-energize the relay and turn off the LED. Re-energization is automatic upon correction of the fault condition.

• Protects against phase loss & phase reversal
• LED indicates both normal and fault conditions
• Compact plug-in case utilizing industry-standard 8 pin octal socket
• 10A SPDT output contacts

Application Data

Phase Loss:
Unit trips on loss of any Phase A, B or C.

Phase Reversal:
Unit trips if rotation (sequence) of the three phases is anything other than A-B-C.

Output Contacts:
10A SPDT @ 240VAC, 1/3HP @ 240VAC (N.O. contact); 1/6HP @ 240VAC (N.C. contact)

Life:
Full Load: 100,000 operations

Response Times:
Operate: 50ms; Release: 50ms

Load (Burden):
3VA

Temperature:
-28^o to 65^o C (-20^o to 150^o F)

Transient Protection:
10,000 volts for 20 microseconds

Mounting:
Uses an 8 pin octal socket. Requires a 600V-rated socket when used on system voltages greater than 300V (Macromatic Product Number 70169-D).

Indicator LED:
Red LED on when all conditions are normal, and off when a fault condition has occurred.

Reset:
Automatic upon correction of fault

Approvals:


When used with Macromatic socket 70169-D rated 600V
