Key-operated switch JUNG 806.28 G — 2P, wired, 250 V AC, 16 A, black/white

JUNG 806.28 G is a key-operated switch with two-pole switching and wired terminals, designed for secure control of electrical circuits in residential and light-commercial installations. The unit accepts AC supply up to 250 V and a nominal switching current of 16 A. The aluminium enclosure measures 90 x 75 x 65 mm and features a metallic anthracite cover with a silver‑grey housing. The device includes a PE terminal and one bottom inlet M20 x 1.5 and is supplied without a locking plate; it is intended for a locking cylinder with an overall length of approximately 40 mm.

Advantages

The switch provides keyed access control to prevent unauthorized operation while retaining a compact footprint suitable for surface mounting. Screw terminals accommodate conductors up to 2.5 mm² for straightforward wiring. The aluminium housing and separate cover offer mechanical protection and a defined mounting volume for the lock cylinder and internal components. The integrated PE terminal and dedicated inlet simplify earthing and cable entry.

How to use

Install the switch on a suitable flat surface and route supply and load conductors through the M20 bottom inlet. Secure conductors to the screw terminals, observing the conductor size limit of 2.5 mm² and ensuring tight, corrosion-free connections. Fit a compatible locking cylinder with an overall length of approximately 40 mm and mount the locking plate separately if required. Connect protective earth to the designated PE terminal. After wiring, verify correct switching operation with the intended key and check that the enclosure is closed properly to maintain protection.

Recommendations

Use a locking cylinder specified for this switch (total length ≈ 40 mm) or the manufacturer’s reference cylinders to maintain expected ingress protection; if a cylinder with key access on both sides is used, water may enter the housing and IP44 protection cannot be guaranteed. For safe operation, observe local electrical regulations, switch off supply before installation, and ensure earthing is correctly connected.
