The DEHNguard DG M TT 275 is a modular, multi-pole Type 2 surge arrester, specifically designed for the protection of electrical installations in TT networks. With its high protection capacity and modular design, this arrester is ideally suited for use in residential buildings, commercial buildings, and industrial installations. The DG M TT 275 reliably protects against dangerous overvoltages and voltage spikes that can be caused by lightning strikes and power grid disturbances, making it an excellent choice for long-lasting and stable surge protection.

Technical details and features:

• Type: Type 2 (effective protection against medium overvoltages and network transients)
• System voltage (Un): 275V AC – ideal for 230/400V networks in TT systems.
• Number of poles: Multi-pole – offers comprehensive protection for all conductors in the TT network.
• Maximum discharge current (Imax): 40 kA – reliably protects against high overvoltages caused by lightning and voltage spikes.
• Nominal leakage current (In): 20 kA – ideal for regular protection against mains disturbances and less intense voltage spikes.
• Modular design: Allows for quick replacement of individual modules and significantly simplifies maintenance.
• Status indicator: Visual wear indicator for quick condition checks and timely maintenance.
• Mounting: DIN rail mounting (35 mm DIN rail) – for space-saving and easy installation in the control cabinet.
