Sfera ShU 750×700×350 IP54 cabinet
The outdoor version with mineral wool insulation is designed to house equipment outside heated premises – on building facades, posts, in industrial zones without permanent climate control. The ShU428 body of 750×700×350 mm holds a mounting panel or DIN rail with metering devices, automation and medium-volume switching devices, and thermal insulation reduces the effect of outdoor temperature changes on the electronics inside. The wall mounting and sealed cable entries make the cabinet a convenient solution for outdoor installation where installation space is limited.

Area of application
The dimensions of 750×700×350 mm allow several rows of circuit breakers, electricity metering devices, terminal blocks, relays and small instrumentation to be placed in the cabinet on a mounting panel or DIN rail. This volume is enough for a metering node, a control automation group or a distribution panel at a facility with a moderate number of outgoing lines.
Mineral wool insulation 50 mm and a gasket around the door perimeter provide additional protection of the equipment from freezing of the body and condensation formation in open-air operation. The wall mounting method simplifies installation on a building wall, post or steel structure without a foundation, and the IP54 protection rating permits operation under exposure to dust and water splashes.
Where it is used:
- electricity metering points at service entrances of buildings and structures;
- lighting control panels on the territories of enterprises and infrastructure facilities;
- automation cabinets for ventilation systems and pumping equipment for outdoor installation;
- distribution nodes at construction sites and temporary facilities;
- communication and telemetry equipment on posts and facades;
- control panels for shut-off valves and I&C on pipelines and production sites.
