CBi 30A 1P+N 3kA Circuit Breaker C3

• The CBI Electric QA(13) 2-Pole (or 1P+N) Miniature Circuit Breaker provides reliable AC circuit protection in an exceptionally compact format.
• Utilizing precise hydraulic-magnetic technology, this breaker offers tripping characteristics independent of ambient temperature (-40°C to +85°C).
• Occupying just 26mm (2 x 13mm modules) on a mini rail, it's ideal for space-constrained panels.
• This version allows for switching and protection of both line and neutral conductors (or two line conductors).
• Compliant with standards like VC 8036 (SANS 556-1) and IEC/EN 60947-2, VDE approved, and CE certified, the QA(13) 2-pole MCB is a dependable choice for residential, commercial, and industrial single-phase applications requiring neutral switching or double-pole protection.

Benefits

• Reliable & Consistent Protection: Hydraulic-magnetic tripping is precise and unaffected by temperature changes.

• Complete Single-Phase Isolation: Switches both line and neutral (or two lines) simultaneously for enhanced safety during maintenance.

• Significant Space Savings: The narrow 26mm profile allows for more circuits in a smaller panel space compared to standard 2-pole breakers.

• Quick Fault Diagnosis: Mid-trip handle clearly indicates an electrical trip versus a manual switch-off.

• Minimized Downtime: Immediate reset capability reduces circuit interruption time after resolving faults.

• High Safety Standards: Complies with rigorous local and international safety regulations.

• Versatile Use: Suitable for main switches in small DBs, specific appliance circuits, or any single-phase load requiring L+N protection/switching.

• Long-Lasting Performance: Robust construction ensures reliability in various environments.

Technical Specifications 

Ideal Use

• Residential Main Switch: Suitable as an incoming main circuit breaker for small distribution boards where L+N switching is desired.

• Single-Phase Appliance Protection: Protecting circuits for larger appliances like geysers, stoves, or air conditioners where double pole isolation is preferred or required.

• Commercial Circuits: Protecting single-phase circuits in commercial installations requiring L+N breaking.

• Industrial Control Panels: Protecting single-phase control circuits or equipment feeds where space is limited.

• Alternative Energy Systems: AC output protection for single-phase inverters.

• Mobile Power Generation: Protecting outputs on smaller generators.

Tips

• Configuration: This unit functions as a linked 1P+N or 2P breaker depending on how it's wired (protecting Line + Switched Neutral or Line 1 + Line 2).

• Certification Check: Ensure the specific current rating (up to 60A for VC 8036, up to 50A for IEC/VDE) meets the requirements and certifications for your installation.

• Mounting: Designed for Mini Rail; optional clips needed for surface mounting.

• Wiring: Use appropriate wire size (0.75-35mm²) per pole. Torque terminals correctly to 2.5 Nm.

• Trip Handle: The linked mid-trip handle clearly indicates a fault on either protected pole.

• Temperature Stability: Ideal for environments with significant temperature swings due to its hydraulic-magnetic nature.

• Isolation: Provides a reliable means of isolating both monitored conductors simultaneously.
