15-240
The MODEL 15 Reverse Phase Correction Relay provides essential protection for industrial systems. Operating at 240VAC with a 50-60Hz frequency range, this device ensures consistent phase monitoring. Its rapid .05-second response and reset times minimize system downtime during phase anomalies, contributing to operational continuity. Robust SPDT 10A output contacts at 240VAC resistive and 3P3T 4A at 480VAC resistive contacts manage diverse load requirements effectively. Transient protection up to 2500V for 10ms safeguards connected equipment from voltage spikes. With an operating temperature range of -20° to +140° F and 0-97% humidity tolerance, the relay maintains performance in demanding industrial environments. The automatic reset function further enhances system reliability. Constructed with a NORYL case material, it offers durability. This unit provides dependable, precise phase correction for critical applications, supported by a 10 million mechanical operation life.
The Time Mark Model 15 was designed to protect your valuable equipment
from the damaging effects of phase reversal by sensing and automatically
correcting for phase reversal. Under normal power conditions, incoming
A B C voltage is passed straight through the device to the A B C output
terminals (4 amps @ 480 VAC resistive max). If the unit detects an
incoming reverse phase condition (C B A), it will light the reverse
phase LED and internally switch 2 of the phases and then pass the
corrected phasing out to output terminals A B C. If your load is higher
than 4 amps @ 480VAC resistive, the Model 15 provides an auxiliary
output relay to put in the control circuit of a remote reversing
contactor. If phasing is correct, the relay will remain in the static
condition (N.C contact will remain closed and N.O. will remain open). If
the Model 15 detects a reverse phase input, the auxiliary output relay
will energize and the relay contacts will switch (N.C contact will open
and N.O. will close).
