A-B 825-P Motor Relay Used as a protective device for three-phase motors
DESCRIPTION: The Allen-Bradley 825-P is a motor relay used as a protective device for three-phase motors.
It has standard protection features such as thermal overload (thermal model, PTC (positive temperature coefficient), overheat, undercurrent (load loss),
current unbalance and phase loss, overcurrent (load seizure), short circuit, ground fault (residual), ground fault (zero sequence), motor start/run and frequency. This unit requires 110-240VAC power input.
About the 825-P
The 825-P is a protective relay for use with three-phase motors. Manufactured by Allen-Bradley, the device is
It provides standard protections such as thermal overload (thermal modeling), PTC (positive temperature coefficient), overheat, undercurrent (load loss), current imbalance, and phase loss.
overcurrent (load seizure), short circuit, ground fault (residual), ground fault (zero sequence), motor start/run and frequency.
For motor start/run protection, this motor relay is capable of starting the motor timer via a protection disable during startup, a startup
notch or pointing device, TCU (Thermal Capacity Utilization) start inhibit, anti-reverse spin timer, emergency start, two-speed protection, reduced voltage start (star-delta), and stall switching to protect the motor.
