Product details
Configured for TN-S supplies, this compact DEHN arrester brings combined Type 1 and Type 2 protection into four DIN modules. It is the option for three-phase installations that need origin-position lightning current protection but do not have eight spare ways to give up.
Key features
- Combined Type 1 and Type 2 protection configured for three-phase TN-S systems
- Four DIN modules, half the width of a full-size combined three-phase arrester
- Prewired for straightforward connection at the intake position
- Application-optimised for compact, simply equipped installations
- Coordinates with Type 2 protection at distribution boards downstream
Typical applications
Typical uses are three-phase intake panels in small industrial and commercial units, workshops, agricultural buildings, packaged plant and equipment cabinets, and refurbishment projects where surge protection is being added to an existing TN-S board with limited space available.
Compliance
Combined Type 1 and Type 2 devices are classified under the BS EN 61643-11 series and are installed at the origin of the installation. BS 7671 requires transient overvoltage risk to be assessed, with Type 1 protection where partial lightning current may enter the installation.
