Siemens Switch Disconnector – 3KA8 Series – 3KA8171-5TE00
The Siemens 3KA8171-5TE00 is a SENTRON 3KA8 switch disconnector designed for safe manual isolation and switching of electrical power circuits in low-voltage power distribution systems. It is widely used in industrial switchboards, MCC panels, and distribution boards where a reliable isolation device is required for maintenance and safety operations.
This device belongs to the 3KA8 series (Size 3 frame class) and is suitable for power distribution applications up to 690 V AC, offering high durability and reliable switching performance under load conditions.
It is a 3-pole + neutral (3PN) variant family option, commonly used as a main isolator switch for feeders, ensuring safe disconnection of circuits without providing overload or short-circuit protection (protection must be provided by upstream devices like MCCB/MCB).
Key Features:
• Siemens SENTRON 3KA8 switch disconnector
