Type 3 surge arrester DACF15S series

type 2for electrical networksanti-surge

Main features

• Type 2 (or 3) AC surge protector (SPD)
• Monitored internal back-up fuse (no external back-up fuse required)
• Internal thermal disconnector with mechanical indicator and optional remote signalling
• Nominal discharge current In: 5 kA; Max discharge current Imax: 15 kA
• Pluggable modular design — one module per phase for multipolar assemblies
• Remote signalling via changeover contact
• Compliance: EN 61643-11 / IEC 61643-11 / UL1449 ed.5

Description
The DACF15S series integrates a monitored internal back-up fuse and a varistor-based thermal disconnector, eliminating the need for an external back-up fuse and simplifying installation at the main switchboard. These SPDs are intended for primary surge protection of single- and three-phase AC networks. Operation of a disconnector activates the mechanical indicator and the optional remote signalling output. The compact, plug-in modules enable fast replacement and minimum footprint in distribution panels.
