Hager SPB413 Type 2 Surge Protection Device 4P 3+1 for TN-S/TT Networks

The Hager SPB413 is a high-performance Type 2 surge protection device engineered to provide robust electrical safety for TN-S and TT network configurations. This 4-pole 3+1 module is specifically designed to mitigate the risks associated with transient overvoltages, effectively shielding sensitive electronic equipment and complex electrical installations from sudden voltage spikes. By integrating this device into your distribution board, you ensure a stable and secure power environment, minimizing the risk of hardware damage and operational downtime in both residential and commercial settings.

Advantages

The primary benefit of the Hager SPB413 lies in its reliable surge suppression capabilities, which are essential for maintaining the longevity of modern electronic devices. Its 3+1 configuration offers a balanced approach to protection, covering both phase-to-neutral and neutral-to-earth paths, which is critical for the safety of TN-S and TT systems. The device is built with high-quality materials that ensure long-term operational stability and consistent performance even under demanding conditions. Its compact design allows for easy integration into standard electrical distribution panels, making it a practical choice for professional installers and facility managers looking to enhance system safety without requiring extensive modifications.

Suitable for

• Residential electrical distribution boards
• Commercial office power systems
• Protection of sensitive electronic appliances
• TN-S and TT network installations

When it may not be suitable

This device is specifically designed for Type 2 surge protection and may not be sufficient for environments requiring Type 1 protection, such as buildings with external lightning protection systems where direct lightning strikes are a primary concern. It is also not intended for use in network configurations other than TN-S or TT.

Key specifications

• Type: 2 (T2)
• Poles: 4P (3+1 configuration)
• Network compatibility: TN-S and TT
• Nominal discharge current: 20kA
• Mounting: DIN rail

How to use

The Hager SPB413 must be installed by a qualified electrician in accordance with local electrical regulations. The device is designed for mounting onto a standard DIN rail within the main distribution board. Connections should be made following the wiring diagram provided with the unit, ensuring that the phase, neutral, and earth conductors are correctly terminated to the corresponding terminals. Once installed, the device operates automatically to suppress transient overvoltages without requiring manual intervention.

What to consider before purchase

• Verify that your electrical network is either TN-S or TT
• Ensure there is sufficient space on the DIN rail in your distribution board
• Confirm that the surge protection level meets the requirements of your connected equipment
• Check if local regulations mandate the use of additional backup protection fuses

Usage recommendations

Regularly inspect the status indicator on the front of the device to ensure it is functioning correctly. If the indicator shows that the protection module has reached its end of life, it should be replaced immediately to maintain the safety of your electrical installation.
