The Schneider Electric Acti 9 C60H-DC Miniature Circuit Breaker is designed for professionals seeking reliable overcurrent protection in DC electrical systems. Its key benefit is its robust breaking capacity of 20 kA, ensuring safety in fault conditions. A minor consideration is its single-pole configuration, which may require multiple units for systems needing multi-phase protection. This guide covers its features, performance, setup, and maintenance.

The Schneider Electric Acti 9 C60H-DC Miniature Circuit Breaker has a nominal voltage of 220V DC.
A Type C tripping characteristic indicates that the breaker will trip between 5 to 10 times its rated current. This makes it suitable for circuits with moderate inrush currents, such as those from fluorescent lighting or small motors.
No, this Acti 9 C60H-DC model is specifically designed for DC (Direct Current) circuits and should not be used in AC (Alternating Current) applications.
The breaking capacity of this circuit breaker is 20 kA (20,000 Amperes).
The circuit breaker can connect conductors with a cross-sectional area ranging from 1 to 25mm².
It mounts onto a standard 35mm DIN rail. Ensure the DC power is off, then clip the breaker onto the rail and connect the positive and negative DC conductors to the appropriate terminals.
It means the product meets certain environmental standards, including RoHS compliance and low levels of hazardous substances, contributing to sustainability.
Verify the connected load does not exceed the breaker's 3A rating. Check for loose connections or potential short circuits in the wiring. If the load involves significant inrush current, consider a breaker with a higher tripping characteristic if appropriate for the system.
Ensure the fault condition that caused the trip has been cleared. Check for any mechanical obstruction preventing the handle from moving to the 'ON' position. If the breaker remains inoperable, it may be damaged and require replacement.
Check that the connected conductors are of the correct size (1-25mm²) and are securely terminated. Ensure the correct torque has been applied as per the installation guidelines. Loose connections are a primary cause of overheating.
