Protective rail connector Simet ZSO 1-10.0 for 10 mm² conductors, green-yellow

Simet ZSO 1-10.0 is a protective rail connector designed for 10 mm² conductors with green-yellow insulation for protective earth (PE) connections. It mounts on standard distribution rails and provides a compact, reliable termination point for earthing conductors in electrical panels, switchgear and distribution boards. The connector is manufactured to ensure stable mechanical fastening and consistent electrical contact for safety-critical protective earth circuits.

Advantages

The connector offers a compact footprint and tool-friendly design that facilitates quick installation on DIN-style rails. Its green-yellow insulation identifies the terminal as intended for protective earth, helping to maintain correct circuit segregation and safety compliance. The product is engineered for consistent contact pressure, reducing the risk of loose connections and maintaining low contact resistance over time.

Suitable for

• Termination of 10 mm² protective earth conductors in distribution boards
• Use in switchgear and electrical control cabinets where rail-mounted PE terminals are required
• Industrial and commercial electrical installations requiring clear identification of earth connections

Key specifications

• Conductor size: suitable for 10 mm² solid or stranded conductors
• Mounting: DIN-style distribution rail mounting
• Insulation color: green-yellow for protective earth identification
• Contact type: screw/clamp style conductor connection for mechanical and electrical retention
• Application: designed for protective earth/PE circuits in panels and enclosures

How to use

Mount the connector onto the distribution rail by snapping or sliding it into position according to rail type, ensuring it is securely seated. Strip the conductor to the appropriate length, insert the 10 mm² protective earth conductor into the terminal and tighten the screw or clamp to the manufacturer-recommended torque to secure electrical and mechanical contact. Verify correct seating on the rail and ensure the tightness of the connection with a torque driver or suitable tool. Follow local electrical codes and safety procedures while working on live or de-energized equipment.

Usage recommendations

Install the Simet ZSO 1-10.0 on compatible DIN-style rails and use it exclusively for protective earth conductors. Confirm conductor cross-section compatibility and apply the correct tightening torque to maintain low contact resistance. Perform periodic inspections for mechanical tightness and signs of corrosion or damage in environments with elevated humidity or vibrations.
