Reliable Motor Protection Against Overloads
An Overload Relay (OLR) is a protective device used in conjunction with contactors to safeguard motors and electrical equipment from excessive current flow caused by overload conditions. By automatically tripping the circuit when prolonged overload is detected, OLRs help prevent damage, overheating, and downtime.
» Protects motors against overloads and phase failures.
» Adjustable current settings for precise protection.
» Bimetallic thermal protection for accurate tripping.
» Compact and easy to integrate with contactors.
» Manual and automatic reset options.

Comprehensive Motor Protection in a Single Device
A Motor Protection Circuit Breaker (MPCB) combines the functions of a circuit breaker and an overload relay, offering complete protection for motors against overloads, short circuits, and phase imbalances. Unlike standard MCBs, MPCBs are specifically designed to handle the unique requirements of motor loads, ensuring both safety and performance.
» Protects against overload, short circuit, and phase loss.
» Adjustable current range for motor-specific settings.
» High breaking capacity with fast disconnection.
» Compact design, saving panel space.
» Manual control switch with ON/OFF/Trip indicators.
» Direct-On-Line (DOL) and Star-Delta motor starters.
» Industrial machinery, pumps, fans, and compressors.
» Motor-driven systems in manufacturing and process plants.
