Electrical enclosure EFB Elektronik 53603.1 Width 150mm Depth 55mm Height 265mm

The EFB Elektronik 53603.1 electrical enclosure is a lockable steel housing designed to protect splices and distribution components. With external dimensions of 150 mm (width) × 55 mm (depth) × 265 mm (height), the enclosure accommodates up to four splice cassettes or one splice cassette plus a distribution plate. The housing includes two cable entries fitted with dust-tight strips and a swivel lid secured by a lock with two keys.

Advantages

The steel construction offers mechanical strength and long-term durability. A lockable swivel lid increases security and access control, while the dust-tight cable entry strips help protect internal components from contamination. The compact footprint suits installations with limited space yet allows flexible internal configuration for splices and distribution plates.
