Switch Disconnector: 3KA8 for power distribution - 3KA8211-5TE00

Product Description

Siemens Switch Disconnector – 3KA8 Series – 3KA8211-5TE00

The Siemens 3KA8211-5TE00 is a SENTRON 3KA8 switch disconnector designed for safe manual isolation and switching of low-voltage power distribution circuits. It is commonly used in industrial switchboards, MCC panels, and distribution boards where a reliable isolating device is required for maintenance and operational safety.

This model belongs to the 3KA8 series (100A class) and is designed for 3-pole + neutral (3PN) power distribution applications, offering strong mechanical durability and reliable switching performance under load conditions. It is used as a main isolator or feeder disconnector, ensuring safe separation of circuits without providing overload or short-circuit protection.

The device is suitable for use in AC power distribution systems up to 690V, with robust construction and clear ON/OFF indication for operational safety.
