Siemens 3TY7403-0AP6 Ac Operated Replacement Coil

Product Description

The SIEMENS 3TY7403-0AP6 is an AC-operated replacement coil designed for use in industrial contactors. The coil generates the electromagnetic field required to engage and disengage contactor contacts, making it a critical component in motor control and load-switching applications. This replacement coil allows technicians to restore contactor function without replacing the full assembly. It is installed by licensed electricians and industrial maintenance professionals working on motor starters, control panels, and related electrical distribution equipment.

This coil is suited for industrial and commercial electrical control systems where contactors manage high-current loads such as motors, HVAC equipment, and machinery. It is a direct replacement part intended for service and maintenance scenarios where the original coil has failed due to overheating, voltage surges, or normal wear. Installers should verify voltage rating compatibility before installation.

Key Features

• AC-operated coil for electromagnetic contactor engagement
• Replacement design allows coil swap without full contactor replacement
• Compact form factor suited for panel-mount contactor assemblies
• Lightweight at 0.32 pounds for easy handling during service

Compatibility

Designed as an OEM-style replacement coil for SIEMENS contactors requiring an AC-operated coil. Verify the contactor series and voltage rating against the 3TY7403-0AP6 specifications before installation.

Installation Notes

Installation should be performed by a qualified electrician following applicable NEC guidelines. De-energize and lock out the panel or control circuit before removing the existing coil or handling the contactor assembly. Confirm coil voltage matches the control circuit voltage before energizing. Improper voltage application can damage the coil or the contactor frame.
