CBI 10A 3P+N 3kA Circuit Breaker C3

• The CBI Electric QA(13) 4-Pole (often configured as 3P+N) Miniature Circuit Breaker offers comprehensive protection for three-phase circuits with a switched neutral in an exceptionally compact design.
• Utilizing reliable hydraulic-magnetic technology, this MCB ensures precise, temperature-independent tripping (-40°C to +85°C).
• Taking up only 52mm (4 x 13mm modules) on a mini rail, it provides simultaneous protection for three phases (L1/L2/L3) and switching for the neutral conductor, rated up to 415 Vac (L-L).
• Compliant with IEC/EN 60947-2 and SANS 556-1 (VC 8036), VDE approved, and CE certified, the QA(13) 4-pole breaker is an ideal space-saving and high-performance solution for industrial machinery, commercial distribution boards, and applications demanding full 4-pole isolation.

Technical Specifications

 Ideal Use

• Three-Phase + Neutral Main Switch: Serving as the main incoming breaker for distribution boards where full 4-pole isolation is required or preferred.

• Industrial Machinery: Protecting three-phase equipment where the neutral also needs to be switched or isolated (e.g., certain control circuits, equipment with L-N components).

• Commercial Distribution: Providing branch circuit protection for three-phase loads requiring neutral switching.

• Data Centers / UPS Systems: Protecting three-phase PDU inputs or outputs where neutral isolation is critical.

• Applications Requiring Full 4-Pole Isolation: Any installation where safety standards mandate simultaneous disconnection of all phases and the neutral conductor.

Tips

• Wiring Configuration: Typically used for L1/L2/L3 + N applications. Ensure correct phase and neutral connections to the designated poles.

• Certification: Confirm the specific current rating and interrupting capacity needed against the required standard (SANS or IEC/VDE). Note the potential difference in maximum current rating (60A vs 50A) between standards.

• Mounting: Installs compactly on Mini Rail.

• Torque: Correctly torque all four pole terminals to 2.5 Nm using the appropriate screwdriver bit.

• Fault Indication: The linked mid-trip handle indicates a fault on any of the three protected phases.

• Temperature Stability: Provides reliable operation in fluctuating ambient temperatures.

• Full Isolation: Offers enhanced safety by isolating all current-carrying conductors (3P+N) simultaneously.
