Cable tray Legrand 020204 — mounting rail 35x15x515mm

Legrand 020204 is a metal mounting rail with a 35 mm profile, 15 mm depth and 515 mm length designed for secure installation of modular electrical and automation devices. The rail provides a standardized support for mounting miniature circuit breakers, relays, terminal blocks and control modules inside distribution boards and control cabinets, and its metal construction offers mechanical strength and the possibility of electrical grounding when installed according to standards.

Advantages

The mounting rail uses a standardized 35 mm DIN profile that simplifies alignment and interchangeability of modular components. Its robust metal construction gives mechanical stability suitable for residential, commercial and light-industrial electrical enclosures, while the 515 mm length fits common device arrangements and reduces the need for custom fittings. The rail supports easy attachment, repositioning and reliable mechanical engagement of DIN-rail devices.

Suitable for

• Mounting miniature circuit breakers and residual current devices in distribution boards
• Securing relays, timers and control modules in automation panels
• Organizing terminal blocks and wiring in control cabinets
• Retrofitting or extending existing DIN-rail installations in homes and small commercial sites

When it may not be suitable

This rail is intended for standard 35 mm DIN-rail modular equipment and may not be suitable for very large, heavy or non-modular devices that require custom brackets or direct panel mounting. The product is a rail component rather than a finished enclosure, so additional hardware and proper panel preparation are required to complete an installation.

Key specifications

• Profile dimensions: 35 mm (width) x 15 mm (depth)
• Length: 515 mm
• Material: metal for mechanical strength and grounding capability
• Compatible mounting: standard 35 mm DIN-rail modular devices

How to use

Fasten the rail to the panel or cabinet backplate using appropriate fasteners and spacing that match the cabinet design, ensuring the rail is level and electrically bonded where grounding is required. Attach modular devices by snapping or sliding them onto the rail following the device manufacturers’ instructions, then verify mechanical engagement and electrical connections before energizing the system. If cutting or joining rails is necessary, use suitable tools and follow safety practices to preserve dimensional accuracy and edge quality.

What to consider before purchase

• Confirm the 35 mm DIN profile and 515 mm length match the space and device requirements of your panel
• Verify material and grounding needs for your installation environment
• Check compatibility with the specific modular devices you plan to mount (breakers, relays, terminal blocks)
• Plan for appropriate mounting hardware, spacing and panel preparation

Usage recommendations

Install and bond the rail according to local electrical codes; use proper fasteners and avoid overloading the rail with devices that exceed the manufacturer’s mechanical limits.
