Screw terminal ZS/ZSO E90 901600

Mounting of cable trays and profiles – reliability in fire protection systems

Screw clamp ZS/ZSO E90 is an element used for solid mounting of mesh cable trays to WW, WWS/WWSO, WPLS, WPTS brackets and profiles. Its design and materials guarantee stability and safety of the installation, especially in demanding conditions.

This clamp is distinguished primarily by fulfilling the E-90 function – a key parameter in systems maintaining functionality in the event of a fire. This means that it ensures at least 90 minutes of reliable operation of devices such as fire alarm systems, fire alarms or emergency lighting. This is particularly important in buildings equipped with water sprinklers.

Strength and materials tailored to needs

Clamp ZS/ZSO E90 is standardly made of galvanized zinc (G), which provides good corrosion resistance. Additionally, versions are available to order:

• FP – zinc flake coating (compliant with PN-EN ISO 10683:2018-11) – provides exceptional corrosion protection, ideal for aggressive environments.
• E – stainless steel – an excellent choice where the highest corrosion resistance and extreme conditions are required.

Thanks to the variety of materials, the clamp can be adapted to the specific requirements of the project and operating conditions. Installation is simple and intuitive for both installers and end-users. The solid construction guarantees long-lasting and trouble-free operation.
