FAQs
What is the primary purpose of the Phoenix Contact 2905470?
Its primary purpose is to protect 3-phase power supply networks from damage caused by lightning strikes and transient overvoltages.
Can I install this surge arrester myself?
No, installation and commissioning must be performed by qualified electrical personnel due to safety regulations and the technical nature of the device.
What type of protection does this device offer?
It offers Type 1 + 2 protection, meaning it can handle direct lightning strikes (Type 1) and subsequent surges (Type 2).
What is the maximum lightning impulse current it can handle?
It has a lightning impulse current (10/350 µs) capacity of 25kA and a total lightning test current capacity of 100 kA.
How do I know if the arrester is working correctly?
The device has an optical status display for at-a-glance checks. A green indicator typically means it's operational, while a red or absent indicator may signify a fault.
What type of power systems is this arrester compatible with?
It is compatible with TN-S and TT system configurations.
Can I use this for a single-phase power supply?
This model is specifically designed for 3-phase power supply networks (L1, L2, L3, N, PE). It is not intended for single-phase applications.
Troubleshooting
Device status indicator shows a fault (e.g., red/faulty)
The surge arrester may have operated to protect the system. It is likely expended and needs replacement by qualified personnel. Ensure the power is disconnected before attempting replacement.
Remote signalling not functioning
Check the wiring connections for the remote signalling terminals. Verify that the signalling contacts within the arrester are functioning correctly and that the connected monitoring system is operational.
Overheating of the device
This could indicate a serious fault or incorrect installation. Immediately disconnect power and have the system inspected by qualified personnel. Ensure proper ventilation around the enclosure.
Pros and Cons
Pros
- Provides robust protection against lightning and surge events.
- High impulse discharge current capacity (25kA) and lightning test current capacity (100 kA).
- Features remote signalling for integrated system monitoring.
- Easy installation on standard 35 mm DIN rails.
- Suitable for various system configurations (TN-S, TT).
Cons
- Requires installation by qualified personnel.
- Primary application is for 3-phase industrial power systems, may be overkill for single-phase residential use.
- Specific conductor cross-section limitations for flexible wiring (2.5mm²).
Setup, Compatibility & Care
Setup:
Installation and commissioning of the Phoenix Contact 2905470 must be performed by qualified electrical professionals only. The device is designed for mounting on a 35 mm DIN rail.
- Ensure the power supply is disconnected before installation.
- Mount the arrester onto the 35 mm DIN rail within the distribution board.
- Connect the line conductors (L1, L2, L3), neutral (N), and protective earth (PE) to the designated terminals, adhering to the maximum conductor cross-section specifications (35mm² for solid, 2.5mm² for fine-strand).
- Connect the remote signalling wires if remote monitoring is required.
- Verify all connections are secure and correctly made according to the system's wiring diagram.
- Restore power and check the device's status indicator.
Compatibility:
- System Configuration: Compatible with TN-S and TT system configurations.
- Voltage: Suitable for nominal AC 240V systems with a maximum continuous voltage of 350V.
- Conductor Size: Accepts solid and stranded conductors up to 35mm², and fine-strand conductors up to 2.5mm².
Care:
- Regular visual inspection of the status indicator is recommended.
- The device requires no user-serviceable parts. If the status indicator shows a fault, the module should be replaced by qualified personnel.
- Keep the area around the arrester clean and free of dust and debris.
