Product Description
The Allen-Bradley 100-D180-VTTB Delta-Wye connector, available in the IEC 100 Contactors and Bulletin 100-D accessories catalog, is a 50mm square reversing device designed for use with 24-250V DC Allen-Bradley 100-D115 to 100-D180 series contactors. As a 3-phase transformer connection utilizing Delta-connected primary and Wye-connected secondary windings, it reduces starting voltage applied to motors and connects via terminal blocks linked to the contactor. Sold individually, this connector is suitable for single-phase or 3-phase transformer applications requiring voltage control and should be installed by a qualified technician.
Is Your Device Showing These Signs?
The Allen Bradley 100-D180-VTTB commonly experiences issues related to coil failure, resulting in the inability to energize the contactor. Terminal block damage from over-torqueing or corrosion is a frequent problem, leading to connection failures. Overload relay tripping due to excessive current draw or incorrect settings is another common fault. Inspect auxiliary contacts for wear or damage, as these impact control circuit functionality. Verify proper voltage supply to the coil and check for any mechanical obstructions preventing proper armature movement.
