Metal junction and branch box PMO1(5/3) 801200

Metal junction and branching box – reliability and safety of installation

This metal junction and branching box PMO1(5/3) is a key element of every electrical installation where safety and continuity of operation are a priority. Designed to operate in the E90 system, it ensures maintaining connection efficiency even for 90 minutes in case of fire – which is particularly important for fire alarm, emergency and evacuation lighting systems. Made of high-quality galvanized and powder-coated steel (RAL 2004), it guarantees durability and corrosion resistance.

Construction and application

The PMO1(5/3) box is characterized by an IP65 protection class, which means effective protection against dust and water jet. Sealing in the range of 7 mm to 18.5 mm ensures the tightness of cable connections. Installation is simple and flexible – the box can be mounted to concrete using steel dowels or to cable trays and ladders using SGKM6x12 screws. Additionally, it can be mounted on a mesh tray using special UP1 or UPP… brackets and SGNM6x12 or SGKM6x12 screws. Inside there is a ceramic terminal block made of heat-resistant ceramic and a cable gland made of halogen-free plastic. The possibility of using M25 swivel cable glands expands its range of applications.
