Distribution Boxes

Different installations place very different demands on a distribution box. TELEBAHN therefore offers configurations that match the electrical system, protection level and installation environment rather than relying on one standard layout.

• AC surge protection boxes: Combine surge protection with practical enclosure and connection arrangements for low-voltage power systems.
• Main distribution protection boxes: Integrate high-capacity protection for incoming power and main distribution applications.
• PV and DC distribution boxes: Coordinate DC surge protection, circuit protection and connection interfaces for photovoltaic systems.
• Weather-resistant boxes: Selected IP65 enclosures support installations exposed to dust, moisture or outdoor conditions.
• Customized configurations: Component layout, protection mode and connection arrangement can follow project requirements.

Key features

Prewired system integration

Factory wiring combines the main protection and connection components before delivery. This reduces field wiring and helps installers complete projects more efficiently.

Protection matched to the system

Different configurations support AC, DC, single-phase and three-phase applications. The protection layout can also match TT, TN and photovoltaic system requirements.

Durable enclosure options

Selected models use robust IP65 enclosures that protect internal components from dust and water ingress. They suit equipment rooms as well as sheltered or exposed outdoor locations.

Practical maintenance access

Organized component layouts make inspection and servicing easier. Replaceable protection modules and accessible connections can also simplify future maintenance.

Clear operating status

Selected configurations include visual status indicators or remote signaling contacts. Maintenance teams can identify protection status without extensive inspection.

Flexible project configuration

TELEBAHN can coordinate SPD type, circuit protection, terminals, connectors and enclosure layout around specific electrical requirements.

Typical applications

TELEBAHN distribution boxes support projects where installers need both electrical protection and a practical enclosure solution. Common applications include:

• Main and sub-distribution systems
• Industrial power installations
• Commercial buildings
• Photovoltaic power systems
• Outdoor electrical equipment
• Utility and infrastructure projects
• Telecommunications facilities
• Control and equipment rooms

More than an enclosure

A well-configured distribution box does more than house electrical components. It determines how protection devices connect, how installers route conductors and how easily technicians can inspect the system later.

Preassembled components also reduce the amount of coordination required on site. When the enclosure, SPD, circuit protection and terminals work as one system, installation becomes cleaner and more predictable.

For outdoor and renewable-energy projects, enclosure protection becomes equally important. Selected TELEBAHN models combine surge protection with IP65 housings to protect internal components under demanding environmental conditions.

Choosing the right distribution box

Start with the electrical system and installation environment rather than enclosure size alone. Important selection factors include:

• AC or DC system
• Nominal system voltage
• Single-phase or three-phase configuration
• TT or TN system arrangement
• Required SPD type and surge rating
• Circuit breaker or fuse requirements
• Indoor or outdoor installation
• Required IP protection level
• Cable and connector interfaces
• Monitoring or remote signaling requirements

TELEBAHN can configure distribution box solutions around different protection schemes, wiring layouts and project specifications.

Power distribution built around the project
