Ls Electric 1324000900 Thermal Overload Relay 15A Class 20

Product Description

The LS ELECTRIC 1324000900 is a three-pole thermal overload relay from the Metasol Series, designed to protect motors and electrical equipment from sustained overcurrent conditions. It operates at up to 690 volts with a 15 A amperage rating and carries a Class 20 trip class, making it suited for loads that require a longer acceleration time before the relay responds. The adjustable current setting range of 12 to 18 A allows field technicians to dial in protection to match the motor nameplate FLA. A 1NO-1NC contact configuration provides both normally open and normally closed outputs for control circuit integration. Licensed electricians and industrial maintenance technicians are the primary installers of this device.

This relay is intended for use in motor control centers, industrial control panels, and machinery that require reliable overload protection in both commercial and industrial environments. It mounts to a standard DIN rail or directly to a panel, giving installers flexibility in enclosure layout. The Metasol Series is a product family from LS ELECTRIC built around IEC-style motor control components. This relay pairs with compatible contactors in motor starter assemblies where coordinated protection is required. It is suited for vertical plane mounting as specified by the manufacturer.

Key Features

• IP20 ingress protection rating for use in standard control enclosures

Compatibility

Designed as an IEC-style thermal overload relay for use within the LS ELECTRIC Metasol Series motor control product family, typically paired with compatible Metasol Series contactors in motor starter assemblies.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the NEC and applicable local codes. De-energize and lock out the control panel before installing or wiring this relay. Screw terminals should be torqued per the manufacturer specification of 7 lb-in for the auxiliary contact conductor connections. Confirm the current adjustment dial is set to match the motor FLA before energizing the circuit.
