Square D Thermal Overload Relay

The Square D Thermal Overload Relay from Square D by Schneider Electric protects electric motors and their circuits from damage caused by sustained overcurrent. It is also called a thermal overload relay or motor overload relay. It is designed to work with TeSys contactors in motor starter assemblies for industrial, commercial, and machinery control applications.

Key Features:

• Bimetallic thermal protection that trips when motor current stays above the set level for too long
• Adjustable current setting dial so the relay can be matched to the motor's full-load current
• Built-in auxiliary contacts for signaling a trip or for interrupting the contactor coil circuit
• Test and reset functions for commissioning and maintenance
• Compact design that mounts directly to a compatible contactor or on a separate mounting base

Square D by Schneider Electric is a trusted name in industrial control and motor protection. This relay line helps extend motor life and reduce unplanned downtime. Several current ranges are available as individual variants to suit different motor ratings.
