773 series junction box connector for solid conductors up to 4 mm²; Transparent housing; White cover; Continuous operating temperature (max.): 105°C; Surrounding air temperature (max.): 60°C (T60)

Quick Connectors in Distribution BoxesDuring distribution box retrofits or expansions, conductors often require extensions or additional clamping points. Individual quick connectors (e.g., 773Series) are approved as interconnect components for building wiring applications per EN 60998. Application standards for building installation (e.g., Parts 510 and 520 from DIN VDE 0100) also place the following requirements on junction box connectors:

•They must be arranged so that operation, inspection, maintenance and access to the removable connectors is simplified.

•It must be possible to test them.

•Conductors connected from outside must be clearly and permanently assigned to their associated circuits.These requirements cannot be met with quick connectors alone. In combination with mounting carriers, the quick connectors clearly meet these requirements, making them comparable to rail-mount terminal blocks. Using quick connectors with mounting carriers in distribution boxes is accepted by testing authorities.
