Surge arrester with pluggable cartridge, Acti9 load centre KQ II A iPRD iKQ, 1P+N, 20kA, type 2+3, with fuse, without remote monitoring

Experience this Acti9 KQ II load centre iPRD iKQ surge arrester which protects industrial and tertiary buildings installations against direct and indirect transient overvoltages. This is a 1P+N modular device with a 2+3 surge arrester class type with a surge adapted backup fuse. There is no remote signalling but there is a front face local signalling with a green flag when the device is opeartional and with a red flag when the device needs to be changed. This surge arrester allows quick replacement of withdrawable cartridges when they are damaged. It is compatible with TT, TN-S and TN-C-S earthing system. It works on a Ue rated operational voltage of 230/240VAC under a frequency of 50Hz or 60 Hz. The Uc maximum continuous operating voltage is 340VAC in differential mode (L-N) and 305VAC in common mode (N-PE). The In nominal discharge current is 20kA growing to a Imax maximum discharge current of 40kA with a L-N protection mode and 40kA growing to a Imax maximum discharge current of 65kA with a N-PE protection mode. The Uoc open circuit voltage is 6000V in differential mode (L-N) and common mode (N-PE). The Up voltage protection level is 1.5kV in differential mode (L-N) and in common mode (N-PE). It is plug-on the chassis. The dimensions are (W) 18mm x (H) 136mm x (D) 83mm. The weight is 148g. The IP degree of protection is IP20 with device wired. The operating temperature is -40°C to +85°C. This product complies with the BS EN 61643-11 standard with the 2012 and A11:2018 amendment. The KQ II load centre A (Single Phase) or B (3 Phase) ranges provide distribution boards allowing to easily install MCB, RCBO as well as SPD devices. Their plug-on features allow for the quick fitting of devices.
