Product Information
Full details
The Phoenix Contact 2908262 is a single-channel electronic circuit breaker designed for 24 V DC systems, offering reliable protection against overload and short circuits. It is ideal for industrial and automation applications where precise and flexible load protection is needed. A key benefit is its narrow 6 mm width, saving valuable control cabinet space. However, its electronic nature means it requires a stable DC power source and careful setting of nominal currents.

FAQs
What is the maximum current this circuit breaker can handle?
The Phoenix Contact 2908262 has an adjustable nominal current range from 1A to 8A. You must set the device to the appropriate current level for your specific load.
Can this circuit breaker be used in AC systems?
No, this circuit breaker is specifically designed and rated for 24 V DC applications.
How do I adjust the nominal current setting?
The device features an electronic adjustment mechanism. Refer to the product's specific manual or markings on the device for the exact procedure to set the desired nominal current.
What does the IP20 rating mean?
IP20 means the device is protected against solid objects larger than 12.5 mm (like a finger) but offers no protection against water or moisture ingress.
What are the dimensions of this circuit breaker?
The device is exceptionally narrow, measuring only 6.2 mm in width, 55.6 mm in depth, and 105.8 mm in height.
Can I use this with standard terminal blocks?
While it's designed for seamless integration with Phoenix Contact's CLIPLINE complete terminal block system, it can be wired into standard systems provided the electrical connections are made correctly and within the specified conductor size limits.
What is the operating temperature range?
The device can operate within a temperature range of -30 °C to +60 °C.
Troubleshooting
Device does not trip under overload conditions.
Verify that the nominal current is set correctly for the load. Ensure the load is actually drawing current above the set threshold. Check that the input voltage is stable at 24 V DC.
Device trips immediately upon power-up.
The set nominal current might be too low for the load's startup current, or there may be a short circuit in the connected load. Check the load for faults or increase the set nominal current if appropriate.
Device is not resetting after tripping.
Ensure the overload or short circuit condition has been cleared. Attempt to reset the device manually according to its operating instructions. If the issue persists, the device may require replacement.
Loose connections at the terminals.
Check all wire connections to the spring clamp terminals. Ensure conductors are properly inserted and secured. Re-terminate any loose wires.
Pros and Cons
Pros
- Extremely narrow width (6 mm) saves significant control cabinet space.
- Adjustable current ratings provide flexibility and reduce the need for multiple device types.
- Easy integration with Phoenix Contact's CLIPLINE complete terminal block system for streamlined wiring.
- Electronic interlock prevents accidental modification of protection settings.
- Suitable for 24 V DC industrial and automation applications.
Cons
- Requires careful setting of nominal current to ensure proper protection.
- Electronic nature may be less robust to power supply fluctuations compared to thermal-magnetic breakers.
- Limited to single-channel protection.
- IP20 rating means it offers minimal protection against liquids.
Setup, Compatibility & Care
Setup:
- Mounting: Securely attach the circuit breaker to a 35 mm DIN rail.
- Wiring: Connect the input power (24 V DC) and the load wiring to the appropriate spring clamp terminals. Ensure conductor cross-sections are within the specified range (0.2-2.5mm² for fine-strand with ferrule, 0.2-4mm² for solid-core).
- Current Setting: Adjust the nominal current using the device's integrated adjustment mechanism to match the protected load's requirements. Refer to the device's markings or documentation for the specific adjustment procedure.
- Bridging: Utilize the integrated bridging option for easy connection to adjacent terminal blocks within the CLIPLINE complete system if needed.
Compatibility:
- Voltage: Primarily designed for 24 V DC systems.
- Terminal Blocks: Fully compatible with Phoenix Contact's CLIPLINE complete terminal block system.
- Conductor Size: Accommodates conductor cross-sections from 0.2 mm² to 4 mm².
Care:
- Cleaning: Keep the device clean and free from dust and debris. Use a dry or slightly damp cloth for cleaning. Avoid using solvents or abrasive cleaners.
- Environment: Ensure the operating temperature remains within the specified range of -30 °C to +60 °C. Avoid exposure to excessive moisture or corrosive substances.
