Connexbox JBX Pro Junction Box

Connexbox JBX Pro — Maintenance-Free Junction Box for WAGO 221 Connectors

The Connexbox JBX Pro is a professional-grade junction box designed for use with WAGO 221 connectors. The JBX Pro delivers secure, compliant and space-efficient terminations — ideal for electricians needing a fast, repeatable and regulation-compliant joint.

Quick, Tidy & Compliant Connections: Purpose-built for WAGO 221-412, 221-413 and 221-415 connectors, the JBX Pro speeds up installation while keeping every connection enclosed and strain-relieved. Each enclosure supports up to 24 individual conductor connections and accepts conductors from 0.14 mm² – 4.0 mm², ensuring full flexibility across lighting and power circuits.

Installer-Friendly Design: Clever cable entry slots and an adjustable gripper mechanism allow cables with overall diameters of 3 mm – 10 mm to be securely held. Two grip settings — medium and maximum — ensure perfect clamping pressure whether you’re working with twin-and-earth or flex. Simply slide the connectors into the dedicated receptacles, route cables through the exit slots and close the lid — no tools required.

Safety & Compliance You Can Trust: Engineered to meet BS EN 60670-22 and BS 5733-MF requirements, the JBX Pro is approved for use in maintenance-free zones such as inaccessible ceiling voids. The enclosure prevents strain on conductors and maintains secure terminations even under vibration or load, giving electricians peace of mind on every install.
