Siemens 75D73251L Coil Kit 277 Volts Ac

Product Description

The SIEMENS 75D73251L is a replacement coil kit rated for 277 volts AC, designed for use in Siemens contactors and motor starters. The coil is the electromagnetic core of a contactor or starter, energizing the device to open or close the power circuit when control voltage is applied. This kit provides a direct replacement coil assembly for field repair or scheduled maintenance, allowing a technician to restore a failed contactor to service without replacing the entire unit. At 277 volts AC, it is suited for lighting and motor control circuits commonly found in commercial electrical distribution panels.

This coil kit is intended for commercial and light industrial applications where 277-volt single-phase control circuits are used. Typical installations include lighting contactors in commercial buildings, motor starter control circuits, and HVAC equipment disconnect or control applications. Licensed electricians and industrial maintenance technicians are the primary installers. The compact form factor makes it well suited for panel-mounted or DIN-rail-mounted contactor assemblies where space is limited.

Key Features

• Rated for 277 volts AC control circuit voltage
• Replacement coil kit format allows repair of existing contactor without full unit replacement
• Compact dimensions suitable for panel-mounted contactors and starters
• Lightweight assembly at 0.38 pounds for easy handling during installation

Compatibility

Designed as an OEM-style replacement coil kit for Siemens contactors and motor starters that accept a 277-volt AC coil assembly. Verify the coil voltage rating and frame size against the existing contactor before installation.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC). De-energize and lock out/tag out all power to the contactor or motor starter before removing the existing coil or handling any internal components. Confirm control circuit voltage matches the 277-volt AC rating of this coil before energizing. Do not force or bend coil leads during installation, as damage to the coil winding will cause immediate or premature failure.
