NVENT HOFFMAN AC04030R5 Modular chassis, 400×300

Why Choose the nVent HOFFMAN AC04030R5 Modular Chassis?

The nVent HOFFMAN AC04030R5 is a versatile modular chassis for DIN-rail components designed for organised installation inside compatible nVent HOFFMAN wall-mounted electrical enclosures. Sized for 400 × 300 mm enclosures, it provides capacity for 33 modules across 3 DIN-rail rows, making it ideal for compact electrical distribution, protection and control assemblies.

As part of the nVent HOFFMAN AC modular chassis range, the AC04030R5 is designed for DIN-rail components with a maximum height of 68 mm. The three equipment rows are arranged at 125 mm centres, providing a structured layout that helps panel builders install modular equipment efficiently while keeping electrical connections and cabling protected behind the front cover.

The chassis assembly measures approximately 380 mm high × 260 mm wide × 98 mm deep and is intended for nominal 400 × 300 mm enclosures. It incorporates galvanised steel DIN rails, mild steel vertical profiles and a mild steel front cover finished in RAL 7035 structured powder coating. The complete assembly includes the slotted front panel, vertical profiles, blank panels, DIN rails and mounting accessories required for installation.

Organised DIN-Rail Installation for Electrical Enclosures

Modular chassis systems provide a structured method of installing circuit protection, switching and control equipment within industrial enclosures. The nVent HOFFMAN AC04030R5 provides three DIN-rail rows and capacity for 33 modules, allowing panel builders to pre-assemble modular components before installing the completed chassis into the enclosure.

The front cover conceals electrical connections and cabling, helping create a clean and protected installation while allowing access to the operating faces of installed modular devices. The chassis is designed for compatible nVent HOFFMAN MAS and ASR enclosures, and a standard enclosure door can be replaced with a glazed door where equipment visibility is required. Installation into stainless steel enclosures requires enclosure machining.
