CBi 25A 1P 6kA Circuit Breaker C2 D/M

• The CBI Electric QF(13) is a high-performance, single-pole miniature circuit breaker (MCB) specifically designed for DIN and Mini Rail mounting (D/M Dual Mount) in industrial and commercial panels. 
• Part of the ultra-compact 13mm-per-module QF range, it utilizes reliable hydraulic-magnetic technology for precise, temperature-independent tripping (-40°C to +85°C).
• This 1-pole breaker, housed in a standard grey shell, provides robust protection for 240 Vac circuits with a 6kA interrupting capacity according to IEC/EN 60947-2 (and other international standards).
• It's an excellent choice for space-saving protection of lighting circuits, control systems, and single-phase loads requiring high reliability and compliance with key international safety standards.

Technical Specifications

 Ideal Use

• Commercial & Industrial Lighting Circuits: Where higher fault levels (up to 6kA) are possible.

• Control Panel Protection: Protecting 240V control circuits, PLCs, power supplies, instrumentation on DIN rail.

• Branch Circuit Protection: Protecting single-phase machinery/equipment feeds with high PFC in DIN rail panels.

• Telecommunications Racks: Protecting AC power feeds to equipment mounted on DIN rails.

• UPS & Alternative Energy: Providing AC output circuit protection in DIN rail based systems.

• OEM Machinery: Integrating reliable, compact circuit protection directly onto DIN rails within machine control panels.

6. Tips

• Select Correct Standard: Ensure 6kA rating to IEC/EN 60947-2 (or other relevant standard) meets installation needs.

• Current Rating Limit: 6kA typically certified up to 25A per IEC 60947-2. Verify certifications if higher currents at 6kA are needed.

• Mounting: Designed specifically for standard DIN rail and Mini Rail Mounting.

• Curve Selection: Choose Curve 1 (Long delay) or Curve 2 (Medium delay) based on the type of load (e.g., Curve 2 for general circuits, Curve 1 potentially for circuits with higher inrush).

• Wiring & Torque: Use appropriate wire size (0.75-25mm² IEC) and apply the 2.5 Nm torque specification for secure connections.

• Temperature Advantage: Use advantageously in panels subject to high operating temperatures or wide ambient swings where thermal breaker performance might be compromised.

• Isolation: Use the breaker as a reliable means to isolate the circuit for maintenance.
