The Motor Protection Relay is a device that protects electric motors from overload and short-circuits. Overload occurs when the load on the motor exceeds its actual rating, which can cause the motor to overheat. Short-circuiting occurs when a metallic conductor, such as a bolt or screw, comes into contact with the motor terminals and creates a path for current to flow. The MP detects these conditions and switches off the circuit, preventing damage to the motor from occurring. Relays can be initiated in a variety of ways, but they all provide the same basic protection: when the current flowing through the motor reaches a certain level, the relay senses and responds to that level. The response is usually to divert current flow away from the motor and into an alternate form, such as a heat sink or an overcurrent protector that will disconnect power entirely. This is done to prevent damage to the motor itself. A motor protection relay is a safety device that monitors the current, voltage and frequency of a single-phase AC motor and disconnects the power supply if the current exceeds the upper or lower setpoint. MPRs are especially useful when used on variable frequency drives (VFD) due to their ability to perform soft starts and stopping with variable torque loads. While they can be used anywhere a motor is used, they are commonly found on pumps and heating/cooling systems.

Selec 600VPR-1-180/300V Voltage Protection Relay

By SELEC

₹2,359

Selec's 600VPR-1-180/300V Voltage Protection Relay monitors the difference between input and output voltage. It prevents the voltage from getting too high or too low. The relay is constructed with a Polyester resin case that provides protection from harsh external environments. Its terminal block is sealed to prevent contamination of internal contacts, and it has an auto-reset function that resets the relay when power is turned off. This feature prevents it from being inadvertently left in an operating condition after maintenance. The relay's voltage threshold is adjustable via a potentiometer, allowing for control over the trip point. Its circuit includes a zero cross detection function, which prevents false triggering from switch contact bounce that can occur during switching surges. This protects against improper operation caused by voltage sags and spikes, as well as electromagnetic interference (EMI) and radio frequency interference (RFI). The relay can be used in a variety of applications including industrial control, motor control, commercial lighting systems, and any other application where over or undervoltage protection is necessary. The Selec 600VPR-1-180/300V Voltage Protection Relay monitors the voltage supplied to a load and provides an indication in the event that over or under voltage occurs. A variable trip time is available ranging from 0.25 sec - 20 sec depending on application requirements. This device can be used with other devices in Selec's range to connect multiple loads to a single supply, or alternatively it can be used with any other brand of device to monitor a separate load. The relay may be programmed to trip at any voltage between 180V AC - 300V AC (L1-L2) and will reset automatically when voltage returns within the specified parameters.
