Overload Relays
Fixed Heater
C2000 RT overload relays provide motor overload protection through fixed bimetal
heaters. These relays are ambient compensated and utilize a differential mechanism
for single-phase sensitivity. The trip setting is adjustable for the range listed.
Overload relays may be set for 4 different operational modes—manual reset only,
automatic reset only, manual reset/stop, or automatic reset/stop. Stop is initiated by pushing the reset button which interrupts the holding circuit in the latter two listed modes.
Overload relays feature visible trip indication, reset on the upstroke, weld check, and
trip test.

Remote Electrical Reset
Remote electrical resets are used in applications where the motor starter is inaccessible
or in automated control systems where it is required to reset the overload relay remotely
after the fault has been cleared. Electrical reset coils are rated for intermittent duty and
for use with momentary contacts. Minimum time .2 sec. on for reliable operation.
Maximum time 1 sec. on/30 sec. off, 5 sec. on/90 sec. off, 10 sec. on/180 sec. off. Power
consumption is 100VA/100 watts.
