66.59% OFF

The GENERIC Digital Voltage Protection with Auto Re-Connect LED Display White, AVP-63 is a critical component in electrical systems designed to protect equipment and circuits from voltage fluctuations, overvoltages, and voltage-related issues. This device serves as a safeguard against electrical faults, ensuring the reliability and longevity of sensitive equipment while minimizing downtime and costly repairs. One of the primary functions of the Voltage Device Protector Relay is to detect voltage irregularities and respond swiftly to mitigate potential damage. It continuously monitors the voltage levels within an electrical system, and when it detects anomalies such as overvoltage, undervoltage, or voltage spikes, it triggers protective measures to prevent harm to connected devices. Overvoltage protection is essential as it guards against voltage surges that can result from lightning strikes, power grid fluctuations, or other external factors. By instantly disconnecting or redirecting the excess voltage, this relay shields valuable equipment, including computers, industrial machinery, and electronic appliances, from potential damage. Similarly, undervoltage protection is vital to prevent voltage drops that can lead to equipment malfunction or shutdowns. The Voltage Device Protector Relay can automatically disconnect the load from the power source in case of prolonged undervoltage, ensuring that equipment operates within safe voltage limits. Another significant feature of this relay is its ability to provide time-delayed protection. In certain situations, momentary voltage fluctuations may occur without causing harm. The relay can be programmed to allow brief fluctuations while responding to prolonged voltage anomalies, reducing the risk of unnecessary equipment disconnection. Many Voltage Device Protector Relays are designed with remote monitoring and communication capabilities, allowing operators to receive real-time notifications and control the relay remotely. This feature is especially valuable for large-scale industrial operations and critical infrastructure, where rapid response to voltage issues is essential to prevent costly downtime. The reliability and precision of the Voltage Device Protector Relay make it an indispensable component in various sectors, including manufacturing, data centers, telecommunications, and healthcare. Its role in safeguarding electrical systems and equipment from voltage-related damage underscores its importance in ensuring uninterrupted operations and minimizing costly repairs and replacements.

Selec Motor Protection Relay MPR3M2-230V 52.5 mm

By SELEC

₹2,359  

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.

Multispan SPP-22(Single Phase preventor) Voltage and Current Protection Relay (Din rail)

By Multispan

₹1,014  

Voltage and current protection relays are designed to monitor the voltage and current levels of a power supply. These devices can protect electrical equipment by shutting off power to the circuit if it exceeds specified limits. Voltage and current protection relays are used in many applications, including industrial, commercial, and residential environments. A voltage protection relay monitors incoming power from the line side of a transformer or generator, which may be connected to an electric utility's distribution system. The relay senses whether the voltage level is too high or low and responds accordingly. If there is no load on the secondary winding of the transformer or generator, its voltage level rises above normal levels due to losses in its windings. A voltage protection relay senses this condition and opens its contacts to disconnect power from any equipment that is connected to it until normal operating levels are restored. If there is too little load on the secondary winding of a transformer or generator, its voltage level drops below normal operating levels because of insufficient energy generated by its windings. A voltage protection relay senses this condition and closes its contacts so that full load is applied once again to equipment connected to it.
