Switch Disconnector: 3KA8 for power distribution - 3KA8341-5UE00

Product Description

Siemens Switch Disconnector – 3KA8 Series – 3KA8341-5UE00

The Siemens 3KA8341-5UE00 is a SENTRON 3KA8 switch disconnector designed for safe manual isolation and switching of low-voltage power distribution systems. It is widely used in industrial switchboards, MCC panels, and main distribution boards where reliable isolation and operational safety are required.

This model belongs to the 3KA8 series (400A class) and is designed for 3-pole + neutral (3PN) applications, making it suitable as a main incomer or feeder isolator in three-phase electrical systems. It ensures safe disconnection of circuits without providing overload or short-circuit protection, which must be handled by upstream protective devices like MCCBs or fuses.

The device is built for high-load switching duty (AC-23A), offering strong mechanical endurance, reliable operation under load conditions, and long service life in demanding industrial environments.
