CEE Straight Panel Sockets Selection Guide
When selecting CEE straight panel sockets, compare 16 A–125 A rating, 3/4/5 poles, flange mounting dimensions (mm), blue/red voltage coding and IP44/IP67 hinged lids.
This guide explains what to look for when choosing products in the CEE Straight Panel Sockets category for combination distribution boxes, generator canopies, UPS cabinets and machine tool panels.
Straight (90°) flange geometry and panel cutout dimensions
CEE straight panel sockets mount perpendicular (90°) to the enclosure face, offering a compact square footprint ideal for densely populated combination boxes. When replacing an existing socket or laying out a cutout, verify the outer flange dimensions (e.g. 55×55, 65×65, 75×75, 85×85 mm), 4-hole fixing centers and rear barrel diameter.
Current rating (16 A – 125 A), pole count (3P / 4P / 5P) and IP44 / IP67 lid
Select Blue 3-pole (2P+E) for 230 V single-phase outlets, Red 4-pole (3P+E) for 400 V three-phase loads without neutral, and Red 5-pole (3P+N+E) for 400 V three-phase + neutral loads. Choose spring-hinged IP44 lids for general panels or bayonet-ring IP67 lids for outdoor washdown and construction environments.

Frequently asked questions
When should I use a straight panel socket instead of an angled panel socket?
Straight panel sockets have a smaller vertical flange footprint, making them the standard choice when arranging multiple sockets side by side on combination boxes or mounting on the underside of an enclosure.
What measurements matter when replacing a damaged panel socket on a combination box?
In addition to matching the current (16 A vs 32 A) and poles (4P vs 5P), measure the square flange width/height (mm) and screw hole center-to-center spacing so it bolts directly onto the existing enclosure cutout.
How much internal clearance is needed behind a straight panel socket?
The rear terminal body protrudes 25 mm to 55 mm inside the enclosure behind the flange, so ensure there is adequate clearance before any internal DIN rail or mounting plate.
