Surge protection limiter exchange module T1,T2 (class B,C) for PV systems MOD. ESM T12 PV 600/6,25 S 002440642

Photovoltaic system protection – reliable replacement module

This surge limiter replacement module, catalog number 002440642, is a key element ensuring the safety and long-term operation of a photovoltaic installation. Designed to work with DC systems, it effectively protects against the effects of lightning strikes and overvoltages in the grid. This is particularly important for PV installations, which are exposed to direct lightning strikes due to their location.

Functionality and application

The ESM T12 PV 600/6.25 S module is a Class T1 and T2 (B, C) component designed for mounting on a TH35 rail. Its main task is to protect against overvoltages in photovoltaic installations. The module design allows for quick and easy replacement in case of damage, minimizing system downtime. Thanks to the use of MOV and GDT technology, it provides effective protection against both impulse and permanent overvoltages. Application in DC installations with a permanent operating voltage of up to 600V.

Key features and benefits

• Versatility: The module meets the requirements of IEC/VDE Class I and II standards, guaranteeing its compatibility with various photovoltaic systems.
• High efficiency: The impulse current In (8/20μs) at 20kA provides effective protection against strong overvoltages.
• Easy replacement: The modular design allows for quick replacement of a damaged element without the need to disassemble the entire protective apparatus. This translates into minimizing costs and installation downtime.
• Compact dimensions: A mounting depth of 572mm and occupying only one module make these limiters easy to integrate with existing electrical infrastructure.
• Safety: The use of MOV and GDT technology ensures reliable protection against impulse and permanent overvoltages.
• Wide application: Ideal for use in photovoltaic installations in both residential and industrial buildings.
• IP20 protection degree: Provides basic protection against accidental contact.

Thanks to these features, the ETI POLAM surge limiter replacement module is an investment in the safety and reliability of the photovoltaic system, which translates into long-term savings and peace of mind for the user.
