Surge protector - HSA-275/4+0, Hakel

The HSA-275/4+0 is a top-quality Type 2+3 (T2+T3) class 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 impulse voltages caused by atmospheric events (lightning ⛈️) or industrial switching. 🔌📡 Key advantages: Thanks to its two-level 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 4+0 configuration is ideal for three-phase TN-S systems. 🛡️💻 Thanks to its fast response time (less than 25 nanoseconds), it discharges the excess energy instantly and does not allow the impulse current to reach your equipment. ⏱️🚀 Note: The device has an indicator that lets us check its status at any time: 🟢 Green means that the device is working properly. 🔴 Red means that 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.
