## Summary description

Simet ZSO1-4.0 is a protective rail connector designed for 4 mm² conductors in a green‑yellow protective color. Intended for grounding/earthing connections on DIN rails or mounting rails, it provides a secure mechanical and electrical connection for protective conductors in electrical installations and distribution panels.

## Long description

Simet ZSO1-4.0 is a protective rail connector for 4 mm² conductors, finished in green-yellow for clear identification of protective earth (PE) connections. Designed to mount on standard DIN or mounting rails, this connector provides a compact, dedicated point for connecting protective conductors in distribution panels and electrical enclosures. The product supports reliable mechanical retention of conductors while ensuring low-resistance electrical continuity required for earthing systems.
Advantages
The connector combines clear protective-color coding with a form factor suited for rail mounting, facilitating organized wiring and rapid identification of protective circuits. Its construction is intended to deliver stable clamping pressure for consistent contact over time and to resist loosening under normal vibration and thermal cycles. The device is compatible with common 4 mm² conductor sizes used in building and industrial installations.
Suitable for
Grounding/earthing connections in residential and commercial distribution panels
Protective conductor termination on DIN rails in switchgear and control cabinets
Field wiring where clear identification of protective earth conductors is required
Key specifications
Conductor cross-section compatibility: 4 mm²
Mounting type: DIN rail / mounting rail compatible
Color: green-yellow (protective earth identification)
Connection method: screw/clamp style for mechanical and electrical retention
Application: protective earthing/grounding in electrical installations
How to use
Mount the connector onto the DIN or mounting rail at the desired position, ensuring firm seating. Strip the insulation from the conductor to the appropriate length for a secure clamp contact, insert the 4 mm² protective conductor into the terminal point and tighten the clamping screw to the recommended torque for the conductor type. Verify that the conductor is held securely and that there is good mechanical and electrical contact before restoring power or energizing the circuit.
Usage recommendations
Use appropriate torque values and correct conductor preparation to maintain low contact resistance. Install in accordance with applicable electrical standards and local regulations. Periodically inspect terminal connections for tightness and corrosion, especially in environments subject to vibration or humidity.
