Surge protective device type 1+2 (BC) 12.5kA 2p+GDS50PV-1000G/12KT1 C482383

Electrical installation protection with surge limiters

A Type 1+2 surge limiter is a key element in protecting the electrical installation from the effects of lightning strikes and voltage surges in the grid. The DS50PV-1000G/12KT1 model, with a surge current discharge capacity of 12.5kA, provides comprehensive protection for both sensitive devices and the entire installation. This is particularly important in residential, commercial buildings and photovoltaic installations, where the risk of damage caused by surges is increased.

This two-pole limiter with an additional protective conductor (2p+G) effectively protects against surges in both the phase, neutral and PE protective conductor. Its design allows for mounting on a 35 mm DIN rail, which facilitates integration with the existing distribution board.

Construction and application

This limiter combines the features of Type 1 and Type 2 limiters, offering a wide range of protection. Type 1 protects against direct lightning strikes, while Type 2 protects against indirect surges resulting from induced voltages or switching of network elements. This means that one limiter can perform the function of two devices, optimizing costs and simplifying installation.

The application of the DS50PV-1000G/12KT1 limiter is wide:

• Home installations: protection of RTV, household appliances, lighting and control systems.
• Commercial buildings: protection of server rooms, alarm and fire protection systems.
• Photovoltaic installations: protection of inverters and solar panels from damage caused by lightning strikes.
• Industrial facilities: protection of machines and production equipment.

Key features and benefits

• High efficiency: a surge current discharge capacity of 12.5kA guarantees effective protection against strong surges.
• Versatility: combining the features of a Type 1 and Type 2 limiter provides comprehensive protection in various conditions.
• Easy installation: the ability to mount on a standard 35 mm DIN rail facilitates integration with the existing electrical installation.
• Safety: compliance with safety standards confirmed by the CE marking ensures reliable operation of the device.
• Durability: solid construction guarantees long-term operation without the need for frequent replacement.
• Protection against damage: minimizes the risk of failure of electrical and electronic equipment caused by surges.
• Cost reduction: prevents costly repairs or replacement of damaged equipment.
