Switch Disconnector: 3KA8 for power distribution - 3KA8231-5TE00

Product Description

Siemens Switch Disconnector – 3KA8 Series – 3KA8231-5TE00

The Siemens 3KA8231-5TE00 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 main distribution boards where a reliable isolating device is required for maintenance and operational safety.

This model belongs to the 3KA8 series (160A class) and is designed for 3-pole + neutral (3PN) applications, making it suitable as a main incomer or feeder isolator in three-phase distribution systems. It ensures safe disconnection of circuits without providing overload or short-circuit protection (these protections are handled by upstream MCCBs/MCBs).

The device is built for high durability, safe load switching (AC-23A duty), and long mechanical life, making it ideal for industrial and commercial electrical installations.
