FAQs
What is the primary function of the GB2CD07 circuit breaker?
Its primary function is to provide short-circuit and overload protection for control circuits and associated industrial equipment, such as solenoid valves and transformers.
What is the voltage and current rating of this breaker?
The nominal input voltage is 250V AC, and the current rating is 2A.
How do I reset the breaker after it trips?
The GB2CD07 is a mechanically reset device. After the fault condition is cleared, you will need to manually reset the toggle switch.
Can this breaker be used for main power distribution?
No, this breaker is specifically designed for control circuits and associated industrial equipment, not for general-purpose AC power distribution.
What does '1P+N' mean for the number of poles?
'1P+N' signifies that the breaker has one protected pole (Live) and one neutral pole connection.
What is the breaking capacity of this device?
The breaking capacity is 15 kA (AC) at its maximum rated voltage of 240V.
What is the warranty period for this product?
The warranty period for this product is 1.5 years.
Troubleshooting
Breaker trips immediately upon energization.
This indicates a short circuit in the protected load or wiring. Inspect the load and all wiring for faults. Ensure the load current does not exceed the 2A rating.
Breaker trips intermittently under normal load.
Check if the load current is consistently exceeding the 2A rating or if there is an underlying issue with the load causing temporary overcurrents. Verify correct breaker rating for the application.
Breaker does not reset after tripping.
Ensure the fault condition that caused the trip has been cleared. If the breaker is damaged, it may need replacement.
Breaker does not trip during a fault.
This is a critical failure. Immediately de-energize the circuit and replace the breaker. Do not attempt to repair.

Setup, Compatibility & Care
Setup:
- Ensure the main power supply is de-energized.
- Mount the GB2CD07 circuit breaker onto a standard 35mm DIN rail by clipping it securely.
- Connect the line conductor to the appropriate terminal (refer to markings for input/output).
- Connect the load conductor to the other terminal.
- Connect the neutral conductor to the designated N pole terminal.
- Verify all connections are tight and secure.
Compatibility:
- This breaker is rated for 250V AC and 2A. Ensure the circuit's voltage and current requirements do not exceed these ratings.
- It is designed for use in control circuits and associated industrial equipment, not for main power distribution.
- Compatible with standard 35mm DIN rail systems.
Care:
- Keep the breaker clean and free from dust and debris. Use a dry cloth for cleaning.
- Periodically inspect terminals for signs of corrosion or loose connections.
- Ensure adequate ventilation around the breaker in the control panel.
