Grooved metal DIN fixed rail general circuit breaker rail

A “grooved metal DIN fixed rail general circuit breaker rail” is basically a DIN rail — a standardized metal mounting rail used in electrical panels to hold circuit breakers, relays, terminal blocks and other control devices. The “grooved”/“fixed” bits refer to the fact that it’s a solid metal rail (often with slight grooves or profile edges) that you permanently mount in an enclosure so devices can snap onto it securely.

It’s the backbone inside electrical control panels where modular devices clip on.

• 📏 Standard Profile: The most common is the 35 mm “top-hat” rail (also called TS35), used in most breaker and relay installations.

• 📦 Material: Usually cold-rolled steel (often zinc-plated) for strength and corrosion resistance.

• 🔌 Function (Mounting Only): The rail itself does not conduct current like a busbar; it’s just a secure mechanical support. Devices clip on and are wired separately.

• DIN rails are used to organise and mount:
  ✔ Miniature Circuit Breakers (MCBs)
  ✔ Residual-Current Devices (RCDs), RCBOs
  ✔ Control relays, contactors, timers, PLCs
  ✔ Terminal blocks and fuses
