JMV’s proficiently developed Class B+C Surge protection Devices
- 1. Class B+C/ Type I+II Single Phase JMV/B+C/# NPE: Class B+C surge protection devices offer solution with combined performance over 8/20 µs and 10/350 µs waveform to withstand against lightning and switching surges. These Surge protectors are also used for the protection of single & three phase lines but the combined protection declares them as the upgraded version of its range. Class B+C surge arresters are dedicatedly known as Type I+II lightning cum switching surge protection devices which are acknowledged for its dual protection in the vicinity of LPZ0-2.
