Circuit Protection

MOVmetal oxide varistor350 VAC460 VDC18 J400 A surgeradial disc

05D561K is a radial MOV for 350 VAC or 460 VDC circuits requiring transient suppression. It clamps to 968 V at the specified 5 A surge test current and is rated for 18 J single-pulse energy.

Best for

  • Transient suppression on circuits up to 350 VAC or 460 VDC continuous voltage
  • Surge protection in consumer and industrial electronics
  • Relay and electromagnetic-valve surge absorption

Avoid if

  • The protected circuit cannot tolerate a clamp level up to 968 V at 5 A
  • Required surge energy, repetition, or fault-current conditions exceed the verified application rating
  • Environmental or compliance requirements need undocumented RoHS, REACH, or lifecycle data

Check before use

  • Confirm worst-case continuous voltage including line tolerance and abnormal conditions
  • Coordinate with a current fuse; use appropriate earth-leakage and thermal protection for line-to-ground use
  • Check mounting clearances and soldering limits for the radial leaded part
