MSB10-400(UL)
Part Number: 561501
MSB10-400(UL)
  • Compact type 2 + 3 surge protector
  • Wall mounting and hard wired connection
  • Status indicators
  • IP66
  • UL1449 ed.5 certified
  • EN 61643-11, IEC 61643-11 compliant

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.
