MENNEKES AMTRON 4Y/4B 500/700 Overvoltage Protection Module (Type 2 SPD, 4-Pole, 40 kA) 18665

Electrical surges can silently damage sensitive EV charging electronics, leading to costly repairs and downtime. The MENNEKES AMTRON 4Y/4B 500/700 Overvoltage Protection Module is a dedicated Type 2 surge protective device (SPD) engineered to shield your AMTRON 4Y/4B 500/700 wallbox from transient overvoltages caused by lightning or switching operations. By clamping harmful voltage spikes, it ensures uninterrupted charging and extends the lifespan of your charging infrastructure.

Who is it for

This module is essential for owners and installers of MENNEKES AMTRON 4Y/4B 500/700 EV charging stations who want to protect their investment against power surges. It is ideal for residential, commercial, and semi-public charging locations where electrical storms or grid fluctuations are a concern.

Main features

• Type 2 surge protection per IEC/EN 61643-11, designed for installation at the origin of the charging circuit.
• High discharge capacity: nominal 20 kA (8/20 µs) and maximum 40 kA (8/20 µs) to handle severe surge events.
• Low voltage protection level (< 1.5 kV) ensures connected equipment is never exposed to damaging residual voltages.
• 4-pole configuration (3P+N) provides complete protection for all active conductors and neutral.
• Visual status indicator (green/red) allows quick verification of protection readiness.
• Fast response time (< 25 ns) reacts instantly to transient overvoltages.
• Compact DIN rail mounting (35 mm) for easy integration inside the AMTRON wallbox.
• Wide operating temperature range (-40°C to +80°C) for reliable performance in harsh environments.

Tips

For optimal protection, install this SPD as close as possible to the incoming power terminals of your AMTRON wallbox. Always follow local electrical codes and use an appropriate upstream fuse to ensure the short-circuit withstand rating is not exceeded. Periodically check the status indicator; if it turns red, replace the module immediately to maintain surge protection.
