Wago 221-503 Mounting Carrier - 3-Conductor Terminal Block 221 Series

The Wago 221-503 is a mounting carrier made for 3-conductor terminal blocks in the 221 Series. It provides a way to secure the terminal block in panel, equipment, or other organized electrical assembly environments where a mounted connector is preferred.

This mounting carrier is designed for 3-conductor terminal blocks in Wago's 221 Series. It is model-specific, so buyers should match it to a 221 Series 3-conductor terminal block rather than assume it fits other conductor counts or product families.

The 221-503 is specifically a mounting carrier, not a terminal block itself. Its role is to hold a compatible 221 Series 3-conductor terminal block in a mounted position, which helps when a more fixed and organized layout is needed.

This model is a white mounting carrier for 3-conductor terminal blocks in the 221 Series and is intended for screw mounting. The listed size reference is 4 mm2, and the product weight is 0.0040 kg.

Yes, this is a very lightweight accessory at 0.0040 kg, which makes it practical for compact assemblies where component organization matters. Its design is focused on supporting a specific 221 Series 3-conductor terminal block rather than serving as a general-purpose mount.
