Short DescriptionOVR T2 1N 40-275 P SPD 40KA 1P+N
Long DescriptionDevices Surge Protection (SPD) are designed to protect electrical and electronic equipment against pulse overvoltage surges (lightning and switching) and performs two main tasks: Limit the surge voltage to the required level, Taps surge current to the ground. SPDs Type 2 are designed for safe ground-fault current pulses at a remote lightning strikes or when switching the power supply system. They are not designed to protect against direct lightning strikes as device type 1, but compared with them provide a lower level of voltage protection. SPD Type 2 is recommended to be installed on the input electrical installations, for which there is no danger of a direct lightning strike, or to use as a second stage of protection after installing Type 1 devices. Application: for residential, commercial and industrial sectors Description: Varistor Compliance with standards: IEC61643-1 / EN61643 -11Type: Type 2 (plug-ins) Number of poles: 1P + N Rated voltage, V: 230 Max. continuous. slave. voltage Uc, In: 275/440pulse current Iimp (10/350) in 1 pole, CA: 40/70 Nominal discharge current In (8/20) through 1 pole, CA: 20/30Voltage protection level Up, KV 1 5 / 1.4 Continuous operating current Ic, mA <1 Weight kg. 0.27 Packing unit: 1
