Product Overview

The Marechal DS9 Decontactor® is a heavy-duty plug and socket system with an integrated switching principle to support safe connection and disconnection practices in demanding LV installations. DS9 industrial plug is rated to 150A with a maximum voltage of 1000V, and is available in GRP or metal casings depending on the environment and installation preference.

For harsh environments, DS9 GRP variants offer high ingress protection options (lid closed and connected plug), while DS9 metal variants provide a robust industrial housing and strong impact resistance. The range includes multiple voltage/polarity configurations with 24 keying positions to help prevent mismating. The Marechal DS Plugs & Sockets are compact, and durable, and sealed with built-in switch allows a wide range of options and mounting options. Decontactor® Plug & Socket-outlets cover all industrial electrical connection requirements.
