CBi Isolator 63A 1P 3kA

• The CBI Electric QA-S-1(13) (Part No. QAL10063) is an ultra-compact, single-pole switch disconnector (isolator) designed for reliable manual switching and isolation of AC circuits up to 240 Vac.
• Part of the space-saving QA(13) range, this 13mm wide module fits neatly onto mini rails.
• Rated for 63 Amps, it provides a dependable means to manually disconnect a single live conductor, compliant with SANS 60947-3 standards.
• Its robust construction, clear ON/OFF handle indication, and LED power indicator make it ideal for use as a local isolation point for circuits or equipment where separate upstream overcurrent protection (fuse or MCB) is already in place. 
• Crucially, this device provides NO automatic overcurrent or short circuit protection.

Features

Benefits

• Safe Circuit Isolation: Allows for the safe manual disconnection of a single circuit for maintenance or control.

• Maximum Space Savings: The extremely narrow 13mm profile is ideal for high-density panels.

• Reliable Manual Switching: Designed for dependable operation at its rated current (63A).

• Clear Visual Status: Handle position and LED clearly indicate whether the circuit is energized or isolated.

• Compliance: Meets the specific requirements for switch disconnectors under SANS 60947-3.

• Robust Construction: Ensures long service life in various installation environments.

• Easy Installation: Mini rail mounting simplifies panel assembly.

Technical Specifications

 Ideal Use

• Local Isolation: Providing a point of disconnection for individual circuits (lighting, power outlets, specific appliances) for maintenance, downstream from the main circuit protection.

• Control Panel Isolation: Isolating specific control circuits or components within a larger panel.

• Equipment Switching: Manually switching individual pieces of single-phase equipment ON/OFF where the current is up to 63A and protection is provided separately.

• Solar PV AC Isolation: Can be used as an AC isolator on the output of single-phase microinverters or string inverters, provided upstream protection exists and local regulations are met.

• Sub-circuit Isolation: Isolating sections of a larger single-phase distribution system.

Tips

• Isolator Only: Emphasize this device DOES NOT provide circuit protection. It must be installed downstream of an appropriately rated fuse or MCB.

• Standard: Ensure SANS 60947-3 compliance is suitable for the intended application (isolator standard, not breaker standard).

• Current Rating: Do not exceed the 63A operational current rating.

• Wiring: Connect the single phase line conductor. Use 0.75-35mm² wire and torque terminals to 2.5 Nm.

• Mounting: Installs directly onto Mini Rail.

• Operation: This is a manual switch only. It will not trip automatically under fault conditions. Use the handle for deliberate ON/OFF operation.
