The Siemens 3TY74630DM4 is a DC contactor coil designed for compatible Siemens 3TF46 and 3TF47 contactors with an economy circuit. It is rated for 220V DC and is used to actuate the contactor when the specified control voltage is applied.
The economy-circuit design is intended for compatible contactor applications where the coil operating arrangement supports reduced holding power after the contactor has been energized. This makes the coil suitable for industrial control systems where efficient contactor operation is required.
The 3TY74630DM4 can be used as a replacement spare component during contactor maintenance, servicing and repair. It is suitable for motor starters, industrial control panels, electrical cabinets, automation systems, manufacturing machinery and OEM equipment.
The Siemens 3TY74630DM4 contactor coil is suitable for:
The coil provides the electromagnetic actuation required for compatible Siemens contactors.
The 3TY74630DM4 is designed for 220V DC control applications.
The economy-circuit configuration is suitable for compatible applications requiring efficient contactor coil operation.
It provides a replacement solution for worn or faulty coils in compatible 3TF46 and 3TF47 contactors.
Replacing a faulty coil can help restore contactor operation without replacing the complete contactor where appropriate.
The Siemens 3TY74630DM4 is a dedicated 220V DC economy-circuit coil for compatible 3TF46/47 contactors. It is suitable for OEMs, panel builders, electrical contractors and maintenance teams looking for Siemens contactor spare parts.
Always verify the contactor model, coil part number, control voltage and economy-circuit configuration before installation.
