Wiska WIB 4/DR — IP65 Terminal Enclosure With DIN Rail (230x180x88mm)
Complete lightweight enclosure with DIN rail pre-installed — one size up from the 3/DR, with more rail length and component depth. The lid is secured with 4 quarter-turn screws, and a retaining tab stops it dropping during installation.
Suitable for wall mounting. Easy to cut and drill on site. Other WIB products are available in sizes up to 460 x 380mm — contact us if you need a different size.
We recommend this size for electrical termination, cable extension, and mounting small power supplies and automation components — good for adding sensors or making minor machinery modifications where the 3/DR doesn't have enough room.

Frequently Asked Questions
What's the difference between this and the WIB 3/DR?
A larger footprint (230x180x88mm vs 165x145x84mm) with more rail length and component depth — enough to house a small power supply as well as terminals.
How does the lid fit?
4 quarter-turn screws secure it, with a retaining tab holding it in place so it can't drop and get lost during installation.
Can this house a small power supply?
Yes — the extra depth over the 3/DR makes room for compact DIN-rail power supplies alongside terminals or relays.
Is this suitable for outdoor cable extension work?
Yes — IP65 rated with a -25°C to 85°C operating range, suitable for extending or joining cables outdoors.
Industry Applications
- Cable extension & termination — IP65 junction point when extending existing circuits
- Small power supply housing — room for a compact PSU alongside terminals or relays
- Electrical & building services contractors — DIN-rail housing for site modifications and sensor additions
