FAQs
What is the main purpose of a Type C tripping characteristic?
A Type C characteristic is designed to handle moderate inrush currents, typically found in inductive loads like motors or transformers, allowing them to start without causing nuisance tripping, while still providing protection against overloads and short circuits.
Can this circuit breaker be used for DC circuits?
While the product description mentions 48V DC, this breaker is primarily designed and rated for AC circuits. Its suitability for DC circuits should be verified for specific applications and voltages, and it may require derating or specific installation configurations.
What does the '1+N' in the description mean?
This indicates that the circuit breaker is a 1-pole (single pole) breaker that also switches the neutral conductor. It provides protection and isolation for both the live and neutral wires of a circuit.
What is the breaking capacity (kA) rating?
The breaking capacity indicates the maximum fault current the circuit breaker can safely interrupt without being destroyed. This model has a breaking capacity of 10 kA according to EN 60898 and 15 kA according to IEC 60947-2.
How do I clean the circuit breaker?
Use a dry or slightly damp cloth to wipe the exterior. Ensure the circuit is de-energized before cleaning. Do not use solvents or abrasive cleaners, and ensure the breaker is completely dry before re-energizing.
What is the warranty period for this product?
Warranty information is typically provided by the seller or manufacturer. Please refer to your purchase documentation or contact EATON INDUSTRIES for specific warranty details.
Can I install this circuit breaker myself?
Installation of circuit breakers involves working with electrical systems and should only be performed by a qualified and licensed electrician to ensure safety and compliance with regulations.
Troubleshooting
Circuit breaker trips immediately upon re-energization.
This indicates a short circuit or a severe overload on the protected circuit. Inspect all connected devices and wiring for faults. If the fault cannot be found, consult a qualified electrician.
Circuit breaker trips intermittently without apparent overload.
This could be due to a faulty appliance, a loose connection, or a wiring issue. Check connected devices for faults. Ensure all terminal connections are secure. The breaker itself may be faulty and require replacement.
Breaker does not trip when tested.
The circuit breaker may be faulty. Test the breaker's tripping function using a suitable test device or by simulating an overload (only if qualified and safe to do so). If faulty, replace the unit.
Contact position indicator is unclear or not visible.
Ensure the breaker is fully engaged or disengaged. If the indicator remains stuck or obstructed, the breaker may need replacement.
Pros and Cons
Pros
- Reliable overcurrent and short-circuit protection.
- Clear visual indicators for contact status.
- Flexible installation options with top and bottom terminals.
- Easy to remove from DIN rail for maintenance.
- Suitable for loads with moderate inrush currents (Type C).
Cons
- Requires professional installation by a qualified electrician.
- Not suitable for flush-mounted installations.
- IP20 degree of protection limits use in wet or dusty environments without additional enclosure.
Setup, Compatibility & Care
Setup:
- Ensure the power to the circuit is completely disconnected before installation.
- Mount the FAZ-C25/1N circuit breaker onto a standard DIN rail (35mm) by clipping it securely in place.
- Connect the main incoming power conductors (line and neutral) to the top terminals. Ensure proper torque is applied to the screw terminals.
- Connect the outgoing circuit conductors to the bottom terminals, again ensuring secure screw connections.
- Verify that the breaker is correctly seated on the DIN rail and all connections are tight.
- Re-energize the circuit carefully and test the breaker's functionality.
Compatibility:
- This breaker is designed for AC circuits with a rated voltage of 230V and frequency of 50-60 Hz.
- It is compatible with standard 35mm DIN mounting rails.
- It can be used with conductor cross-sections from 1mm² to 25mm² (solid or multi-wired).
- Additional equipment, such as auxiliary contacts or alarm switches, can be added to the side.
Care:
- The circuit breaker is designed for low maintenance. Keep the exterior clean and free from dust and debris.
- Periodically inspect terminal connections for tightness, especially if vibration is present.
- The degree of protection is IP20, meaning it should be installed in a dry, protected environment. Avoid exposure to moisture or excessive dust.
