Compact Type 2 hard wired surge protector

2-port MLPCA1-230L-DL
Part Number 835283
2-port MLPCA1-230L-DL
  • Compact type 2+3 surge protector
  • For protection class I equipment
  • Easy installation due to two-port design
  • Status signalling
  • Unit defective - disconnection from mains and power circuit disconnection
  • Meets IEC 61643-11 and EN 61643-11 standards IEC 61643-21 and EN 61643-21
  • Particularly suitable for end circuits e.g. LED lighting with protection of control via DALI

MSB10 surge protectors Type 2 (or 3) are designed for effective protection of sensitive equipment, in addition to the surge protector installation (coordination surge protector). These surge protectors utilize a compact and economica scheme based varistors, to obtain a power flow relevant for secondary protection.
