Metal junction and branching box PMO1(3/3) E90 801300

Metal junction and branching box – reliability and safety in one

The PMO1(3/3) box is a solid solution for making electrical connections and branches, designed for demanding applications. Made of high-quality galvanized steel, powder-coated in RAL 2004, it provides durable protection against corrosion and mechanical damage. Its construction guarantees safe operation of the electrical installation, especially in places exposed to difficult conditions.

Functionality and application

The PMO1(3/3) box meets the E90 function, which means it ensures the continued operation of electrical circuits for at least 90 minutes in the event of a fire – in accordance with DIN 4102 part 12. This is a key solution for fire protection, alarm and emergency lighting systems. Thanks to the IP65 protection class, it is resistant to dust and water ingress, allowing it to be used both indoors and outdoors. The sealing range from 7 mm to 18.5 mm allows it to be adapted to different cable diameters.

• Mounting: The box is adapted for mounting using external mounting brackets to concrete (using steel dowels) and to cable trays and ladders (using SGKM6x12 screws). It is also possible to mount on a mesh tray using special brackets (UP1 or UPP…) and SGNM6x12 or SGKM6x12 screws.
• Construction: The terminal block is made of ceramic resistant to high temperatures, and the cable gland is made of halogen-free plastic – this guarantees the safety and durability of the connections.
• Compatibility: The possibility of using M25 swivel cable glands increases the flexibility of the installation.
• Dimensions: Compact dimensions (100 mm x 50 mm x 100 mm) make it easy to install even in tight spaces.

Safety and compliance with standards

The PMO1(3/3) box is not only solid construction, but above all a high level of safety confirmed by certificates and compliance with DIN 4102-12 standards. The E90 performance maintenance system ensures the continuity of critical circuits in emergency situations. This makes this box an ideal choice for installers and investors who care about the safety of people and property.
