Advanced Motor Protection for Industrial Applications

Our overload relay safeguards three-phase motors against overheating and electrical faults, aligning with IEC vibration standards and IP20 protection. The adjustable current setting allows precise adaptation for various motor sizes, providing dependable defense in environments with temperatures ranging from -20C to 60C. Its compact, rectangular design fits seamlessly into standard panels, offering hassle-free installation and consistent energy efficiency.

Flexible and User-Friendly Operation

This relay offers both manual and automatic reset functionality to fit diverse operational preferences. An electrical test button and stop control facilitate periodic testing and immediate interruption, while auxiliary contacts expand control capabilities. The screw terminal connection and moulded surface finish ensure ease of setup and enduring reliability, making it a preferred choice for distributors, manufacturers, and service providers across India.

FAQ's of OVER LOAD RELAY:

Q: How does the overload relay enhance motor protection in industrial automation environments?

A: The overload relay monitors electrical current and instantly disconnects power during severe overloads, protecting motors from overheating or damage. Its precise Trip Class 10A ensures rapid intervention, reducing downtime and maintenance costs in industrial automation systems.

Q: What steps are involved in resetting the relay after a trip event?

A: After an overload trip, the relay can be reset manually using the reset button, or it may auto-reset depending on your selected mode. Ensure the fault is cleared before resetting to maintain safe and reliable motor operation.

Q: When should external short circuit protection be used with this relay?

A: Although the overload relay protects against overloads, it does not provide built-in short circuit protection. External protection such as fuses or circuit breakers must be installed to safeguard electrical circuits from short circuit conditions.

Q: Where can this overload relay be installed, and what are the mounting options?

A: The relay supports both direct and panel mounting, allowing installation in control panels, motor starters, or industrial enclosures. Its compact, rectangular build and screw terminal connections make integration into new or existing systems straightforward.

Q: What benefits do the silver alloy contacts and polycarbonate housing offer?

A: Silver alloy contacts provide superior conductivity and longevity, resulting in reliable switching performance. The polycarbonate housing and thermoplastic insulation enhance mechanical strength, safety, and resistance to harsh operational conditions.

Q: How can users test the relay's functionality without disconnecting the load?

A: The integrated electrical test button allows users to simulate a trip and verify the relay's operation and auxiliary contact functionality without disconnecting the actual load, facilitating safe and regular system checks.
