Metal junction and branching box PMPO. Junction and branching box, Ui=400 V, with retention of connection function E30 / E60 / E90 according to DIN 4102 part 12 803060

Metal junction and branching box – safety and functionality in one

The PMPO box is a reliable solution for connecting and branching cables and wires in electrical installations where maintaining fire safety functions is crucial. Designed to operate at voltages up to 400V, it meets the requirements of DIN 4102 part 12, guaranteeing circuit continuity for E30, E60 or E90 time – depending on the needs and specifications of the installation. This is a solid proposition for both professional installers and end-users who value safety and durability.

Construction and application

Made of high-quality galvanized steel (PM...) or stainless steel (PMO...E), the PMPO box provides resistance to corrosion and mechanical damage. Powder coating (RAL 2004 for galvanized steel and RAL 2003 for stainless steel) further protects the structure and gives it an aesthetic appearance. Inside there is a ceramic terminal block made of heat-resistant ceramic, which is crucial for maintaining the function of the box in the event of a fire. The cable gland made of halogen-free plastic ensures tightness and additional safety.

The PMPO box finds application in public buildings, industrial facilities and anywhere where maintaining the continuity of electrical circuits in fire conditions is required. It is ideal for installing fire protection systems, emergency lighting and other critical circuits.

Key features and benefits
