CBi 10A 3P 6kA Circuit Breaker C2 D/M

• The CBI Electric QA(13) 3-Pole Miniature Circuit Breaker offers high-capacity protection for three-phase AC circuits up to 415 Vac in an extremely compact, 39mm wide (3x13mm) package.
• This Dual Mount breaker (compatible with DIN and Mini rails) utilizes advanced hydraulic-magnetic technology, providing precise, temperature-independent tripping performance across a wide operating range (-40°C to +85°C).
• Featuring a Medium time delay (Curve 2) suitable for general-purpose loads, and a robust 6kA interrupting capacity (to IEC/EN 60947-2 and other standards), this black-shelled MCB is an ideal solution for space-constrained industrial control panels, machinery protection, and commercial distribution applications requiring reliable three-phase protection.

Technical Specifications

Ideal Use

• Three-Phase Motor Circuits: Protection for small to medium 3-phase motors with moderate starting currents.

• Industrial Machinery Feeds: Branch circuit protection for 415V three-phase equipment.

• Commercial Distribution Panels: Outgoing circuits in panels where 6kA rating and space saving are required.

• HVAC Systems: Protecting three-phase compressors, fans, or heating elements with moderate inrush.

• General Three-Phase Loads: Suitable for resistive loads, lighting, and equipment compatible with a Curve 2 trip characteristic.

Tips

• Voltage Check: Ensure the system is 415 Vac (Line-to-Line) as this breaker is rated accordingly.

• Interrupting Capacity: Confirm the 6kA rating is sufficient for the installation's prospective fault current.

• Curve Suitability: Curve 2 is general purpose; evaluate if Curve 1 (Long Delay) might be needed for loads with very high starting currents (if available in this configuration).

• Mounting Choice: Utilize the flexibility of Dual Mount for either DIN or Mini rail systems.

• Wiring: Connect L1, L2, L3 phases correctly. Use appropriate wire size (0.75-25mm² IEC) and apply 2.5 Nm (IEC) torque to all terminals.

• Temperature Advantage: Benefit from stable hydraulic-magnetic performance in varying ambient temperatures.

• Isolation: Use as a reliable 3-pole isolating switch for maintenance safety.
