CBI Isolator 63A 3P 3kA

• The CBI Electric QA-S-3(13) (Part No. QAL30063) is an exceptionally compact, 3-pole switch disconnector (isolator) designed for reliable manual switching and isolation of three-phase AC circuits up to 415 Vac.
• As part of the innovative QA(13) range, this 39mm wide (3 x 13mm modules) unit offers significant space savings on mini rails.
• Rated for a 63 Amp operational current and complying with SANS 60947-3, it provides a dependable method for simultaneously disconnecting three live conductors (L1/L2/L3).
• Featuring robust construction, clear ON/OFF handle status, and an LED power indicator, the QA-S-3(13) is ideal for main isolation points in three-phase distribution boards or for safely isolating machinery during maintenance, where overcurrent protection is provided by separate upstream devices. 
• Crucially, this isolator offers NO automatic circuit protection.

Technical Specification

 Ideal Use

• Main Isolator (Three Phase): Ideal as the main incoming switch disconnector for three-phase distribution boards or panels.

• Machine Isolation: Providing a local, lockable point of safe isolation for three-phase machinery during maintenance or servicing.

• Three-Phase Load Switching: Manually switching three-phase loads (motors, heaters, etc.) up to 63A where circuit protection is provided upstream.

• Compact Panel Builds: Essential for applications demanding high component density on the DIN rail.

• HVAC System Isolation: Disconnecting three-phase HVAC units or components.

Tips

• Isolator Function ONLY: This device provides NO automatic protection against overloads or short circuits. It must be installed downstream of appropriately rated fuses or MCBs for circuit safety.

• Standard: Ensure compliance with SANS 60947-3 is sufficient for the intended use as an isolator.

• Application Voltage: Rated for 415 Vac Line-to-Line systems.

• Wiring: Connect L1, L2, and L3 to the respective poles. Use appropriately sized conductors (0.75-35mm²) and torque terminals to 2.5 Nm.

• Operation: Intended for manual ON/OFF switching only. It will not trip automatically.

• Upstream Protection: Select upstream protection (fuse/MCB) according to the load and cable characteristics, ensuring coordination with the isolator's conditional short-circuit rating if applicable.
