SPD surge protector T1+T2 4P TN-S/TT network Iimp=100kA Up1, 5kV contact SPA801

Surge protection in the installation – reliable surge arrester Hager SPA801

This four-pole surge arrester of class T1+T2 is a key element ensuring the safety of electrical installations in residential and commercial buildings. Designed for TN-S, TN-C, TN-C-S and TT networks, it effectively protects against the effects of lightning strikes and switching surges. Its versatility will be appreciated by both installers and end-users, who gain confidence in the reliable protection of valuable equipment.

The SPA801 surge arrester is distinguished by its high efficiency – it withstands an impulse current of 100 kA (8/20 µs) and 25 kA (10/350 µs). A protection level of 1.5 kV guarantees effective reduction of voltage to safe values. The built-in remote signaling contact allows continuous monitoring of the device's status and informs about any activation – this is particularly important in systems requiring continuous power supply.

Construction and mounting

Mounting the surge arrester is extremely simple thanks to the standard DIN TH-35 mm mounting rail. Compact dimensions (8 modules) allow for easy adaptation to the existing switchgear cabinet. Wire cross-sections up to 50 mm² (solid/stranded) and 35 mm² (flexible) ensure compatibility with most installations. Additionally, the optical indication of the device's status facilitates quick diagnostics.

Application and benefits

• Versatility: The possibility of use in various types of networks (TN-S, TN-C, TT, TN-C-S) makes the surge arrester ideal for new installations and modernization of existing ones.
• Effective protection: Provides protection against lightning and switching surges, minimizing the risk of damage to electrical equipment.
• Status monitoring: The built-in remote signaling contact enables continuous monitoring of the device's status and quick reaction in case of failure.
