Wago 221-523 Mounting Carrier for 221 Series, 3-Conductor, Snap-In, White, Pack of 10

The WAGO 221-523 is a mounting carrier for 3-conductor 221 Series splicing/terminal blocks designed for vertical mounting using a snap-in mounting foot. It accepts 221 Series connectors for conductors up to 4 mm² (24–12 AWG) and provides a defined mechanical fixing point in luminaires, panels, and enclosures. The carrier is made from polyamide PA66 with UL 94 V0 flammability, and features a compact white housing with approx. 57.3 × 23.7 × 16.9 mm overall dimensions for space-constrained assemblies. The 221-523 is suitable where 3-conductor 221 Series terminal blocks must be secured against movement or vibration while maintaining access for testing and service. The snap-in mounting foot allows fast, tool-less insertion into properly dimensioned cutouts or sheet metal features, giving repeatable positioning in OEM lighting, appliance, and control equipment builds. Low fire load and the insulating PA66 material support use in building services and industrial control cabinets where documented material behavior is required.
