Hager KS18A Morsetto per guida S 35-120 mm², per barre conduttrici 12x5/10 mm

In power distribution and industrial control panels, connecting large conductors to busbars often requires bulky, unreliable adapters. The Hager KS18A S-Rail Clamp solves this by providing a direct, screw-terminal connection for conductors from 35 to 120 mm² onto 12x5 mm or 12x10 mm busbars, ensuring a secure and low-resistance joint without additional hardware.

Who is it for

This clamp is intended for electrical panel builders, industrial electricians, and maintenance technicians who need to terminate rigid or flexible copper conductors onto S-rail busbars in low-voltage distribution systems. It is suitable for applications up to 1000 V AC or 1500 V DC, making it versatile for both AC and DC installations.

Tips

Ensure the busbar and conductor are clean before installation. Use a calibrated torque wrench set to 12 Nm to avoid under- or over-tightening. For flexible conductors, use ferrules to prevent strand breakage and achieve optimal contact. Always de-energize the panel before installation.
