Busbar rail 1F ELEKTROPLAST S-121F-12 (MPN 45.302)

Single-phase busbar rail ELEKTROPLAST S-121F-12 is a compact conductive rail designed for installation in distribution boards and switchgear. It provides a consistent conductive path for one phase, enabling straightforward connection of modular devices and safe mounting of protective and switching equipment. The product is intended for residential and light commercial electrical installations where a space-saving, reliable phase conductor is required.

Advantages

The busbar rail offers a compact profile that reduces clutter inside distribution enclosures and simplifies wiring runs. Manufactured to durable electrical standards, it ensures steady conductivity and mechanical stability for mounted devices. Installation is fast due to its standardized shape and mounting compatibility with common DIN-rail systems, reducing labor time during assembly or upgrades.

Suitable for

• Single-phase distribution boards in homes and apartments
• Light commercial switchgear and small service panels
• Mounting of circuit breakers, residual current devices and contactors
• Retrofit and new-build electrical installations requiring tidy conductor routing

Key specifications

• Configuration: single-phase conductor rail
• Form factor: compact rail for enclosure mounting
• Compatibility: designed for use with standard modular switching and protective devices
• Application environment: residential and light commercial electrical panels
• Function: provides a reliable conductive path and mechanical support for mounted devices

How to use

Mount the busbar rail inside the distribution board according to enclosure layout and local electrical codes. Secure the rail to the mounting surface or DIN rail using the appropriate fasteners, ensuring firm mechanical contact and correct alignment with modular devices. Connect incoming and outgoing phase conductors to the designated terminals or connection points and snap or screw modular devices onto the rail following manufacturer instructions for each device. Verify all connections are tight and protected before energizing the circuit.

Usage recommendations

Ensure installation and any modifications are performed by a qualified electrician and comply with applicable national wiring regulations. Confirm compatibility of the busbar rail with the chosen protective and switching devices and respect the rated current and clearances specified by device manufacturers. Regular visual inspection for secure mounting and clean contacts is advised as part of routine electrical maintenance.
