Surge protector - HLSA25-275/3+1, Hakel

The HLSA25-275/3+1 is a premium-quality Type 1+2+3 (T1+T2+T3) class combined surge protector from the Czech brand Hakel. The device provides reliable protection of a three-phase electrical network and the sensitive equipment in it against surge voltages caused by atmospheric events (direct lightning strike ⛈️) or industrial switching. 🔌📡 Key advantages: Maximum current capacity (I = 25 kA): the HLSA25 series is designed to protect critical infrastructure. Its 3+1 configuration (three ultra-high-power varistors and a gas discharge tube) protects all three phases and provides full isolation between neutral and ground. This is the best solution for TT and TN-S systems, where the highest safety standard is required. 🏗️⚡ Thanks to its fast response time (less than 25 nanoseconds), it instantly and safely discharges the colossal energy caused by lightning and does not allow the surge current to reach your equipment. ⏱️🚀 Note: The device has an indicator that allows you to check its status at any time: 🟢 Green means that the device is working properly. 🔴 Red means that the protection resource is exhausted and the device needs to be replaced. The product fully meets international safety requirements (IEC/EN 61643-11), which ensures its long and reliable operation.
