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

HSA-275/3+1 is a top-quality Type 2+3 (T2+T3) class surge protective device 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 (lightning ⛈️) or industrial switching. 🔌📡 Key advantages: Thanks to two-stage protection (T2+T3), a single device simultaneously ensures the safety of both the electrical distribution network and the sensitive electronics connected to it (servers, computers, Smart Home systems). Its 3+1 configuration (varistors on the phases and a gas discharge tube on the neutral) is ideal for TT and TN-S systems, as it completely eliminates leakage current to ground. 🛡️💻 Thanks to its fast response time (less than 25 nanoseconds), it instantly discharges excess energy and does not allow the surge current to reach your equipment. ⏱️🚀 Note: The device has an indicator that allows us to check its status at any time: 🟢 Green means the device is working properly. 🔴 Red means the protection resource is exhausted and it needs to be replaced. The product fully meets international safety requirements (IEC/EN 61643-11), which ensures its long and reliable operation.
