Phoenix Contact 2839130 Surge Protector 240 V

The Phoenix Contact 2839130 is a high-performance surge voltage arrester designed to protect electrical systems operating at a nominal voltage of 230 V AC. This device consists of a robust base element equipped with a remote indicator contact and a ground connector, featuring a high-capacity varistor to effectively manage voltage spikes. Housed in a durable black polyamide casing with an IP20 protection rating, it is engineered for reliable integration into industrial and commercial electrical infrastructures.

Advantages

This surge protector offers exceptional reliability by utilizing a high-capacity varistor that efficiently diverts transient overvoltages away from sensitive equipment. The inclusion of a remote indicator contact allows for real-time monitoring of the device status, ensuring that maintenance teams are alerted immediately if the protection module requires replacement. Its compact design and compatibility with standard mounting rails facilitate a straightforward installation process, while the durable construction ensures long-term operational safety in demanding environments.

Suitable for

• Industrial control cabinets and automation systems
• Commercial electrical distribution boards
• Protection of sensitive electronic equipment against voltage surges
• Systems requiring remote monitoring of surge protection status

When it may not be suitable

This device is specifically designed for 230 V AC electrical systems and should not be used in DC circuits or systems exceeding the specified voltage ratings. It is not intended for outdoor use without an additional protective enclosure, as the IP20 rating indicates it is not protected against water ingress.

Key specifications

• Nominal voltage: 230 V AC
• Protection type: 1-channel surge arrester
• Mounting type: NS 35/7.5 DIN rail
• Housing material: Polyamide
• Protection rating: IP20
• Features: Remote indicator contact, high-capacity varistor

How to use

The surge protector is designed for mounting on a standard NS 35/7.5 DIN rail. Ensure the power supply is disconnected before installation. Secure the base element onto the rail and connect the phase, neutral, and ground wires according to the local electrical codes and the provided wiring diagram. The remote indicator contact can be wired to a monitoring system to provide status updates. Once installed, verify all connections are tight and the device is properly seated before restoring power.

What to consider before purchase

• Verify that your system voltage matches the 230 V AC nominal rating.
• Ensure there is sufficient space on the DIN rail within your distribution board.
• Check if your monitoring system is compatible with the remote indicator contact output.
• Confirm that the environmental conditions are suitable for an IP20-rated device.

Usage recommendations

Regularly inspect the status of the surge protector via the remote indicator contact to ensure the varistor remains functional. If the indicator signals a fault, replace the protective module immediately to maintain continuous equipment safety.
