Product Information
Full details
The Schneider Electric Acti 9 iC60N is a single-pole miniature circuit breaker (MCB) designed for electrical installations requiring protection against short circuits and overloads. It is ideal for electricians and maintenance professionals working with TN and IT neutral systems, offering robust protection for circuits and personnel. A key benefit is its multi-standard compliance, ensuring reliability and safety. However, its 1A current rating means it is suited for specific low-current applications rather than general-purpose power distribution.

FAQs
What is the primary function of the Acti 9 iC60N?
The primary function is to protect electrical circuits against overcurrents (overloads and short circuits) and to provide protection against indirect contact in specific neutral systems.
What does 'Type C' tripping characteristic mean?
Type C indicates that the circuit breaker will trip when the current reaches 5 to 10 times its rated current. This makes it suitable for circuits with moderate inductive loads that have a higher inrush current, such as lighting or small motors.
Can this circuit breaker be used in a residential main panel?
With a 1A rating, this specific model is generally too low for main residential panel use, which typically requires higher amperage breakers. It is more suited for specific control circuits or low-power equipment.
What is the breaking capacity of this breaker?
The breaking capacity is 10 kA, meaning it can safely interrupt a fault current up to 10,000 Amperes.
What are the operating temperature limits?
The operating temperature range is from -35°C to 70°C.
Is this breaker suitable for outdoor use?
No, the IP20 rating indicates it is protected against solid objects larger than 12.5mm but not against water or dust ingress, making it suitable only for indoor, dry environments.
How do I determine if I need a 1-pole breaker?
A 1-pole breaker is used for single-phase circuits that require protection on the live conductor only. Common applications include control circuits, certain lighting circuits, and electronics requiring low current protection.
Troubleshooting
Circuit breaker trips frequently
Check for overload on the circuit. Ensure the connected load does not exceed the 1A rating. Inspect wiring for potential short circuits. Verify that the Type C tripping characteristics are appropriate for the connected load's inrush current.
Circuit breaker will not reset after tripping
Confirm that the fault condition has been cleared. The breaker may have tripped due to a severe fault or internal issue. If the fault is cleared and it still won't reset, the breaker may need to be replaced.
No power to the circuit, but breaker is not tripped
Check that the breaker is in the ON position. Verify power supply to the breaker input. Test for voltage at the breaker output terminals. Ensure all connections are secure.
Pros and Cons
Pros
- Provides reliable overcurrent and short-circuit protection.
- Certified by third parties, ensuring high quality and safety.
- Designed for easy installation on standard DIN rails.
- Type C tripping curve is suitable for applications with moderate inrush currents.
- Compact 18mm width saves space in electrical panels.
Cons
- 1A rated current limits its use to low-power circuits.
- Single-pole configuration is not suitable for all types of circuits (e.g., 3-phase loads).
- Requires DIN rail mounting, not surface mountable without an adapter.
- IP20 rating means it's suitable for indoor use only and protected against solid objects larger than 12.5mm, but not against water.
Setup, Compatibility & Care
Setup: The Acti 9 iC60N is designed for DIN rail mounting. Ensure the DIN rail is securely installed in your electrical enclosure. Slide the circuit breaker onto the rail, engaging the clips at the top or bottom, and push firmly until it locks into place. Connect the live conductor to the line terminal and the load to the load terminal. Ensure all connections are tight.
Compatibility: This breaker is compatible with AC systems operating at up to 240V and DC systems up to 72V. It is designed for use in TN and IT neutral systems. It is suitable for use with conductors of appropriate size that meet the 1A rating requirements.
Care: The Acti 9 iC60N requires minimal maintenance. Keep the unit clean and free from dust and moisture. Periodically check connections for tightness. Regular testing of the circuit breaker's functionality (tripping test) is recommended as per local electrical codes and standards to ensure its continued reliable operation. Ensure the operating environment stays within the specified temperature range of -35°C to 70°C.
