Maximum Safety in Surge Protection
SPD/MOV is the Victim of Temporary Overvoltage (TOV)
SPDs not properly designed or incorrectly used and unprotected MOVs may go into thermal runaway, resulting in short circuit, overheating, smoke and potentially fire hazard due to:
- End of life
- Sustained abnormal overvoltage / Temporary Overvoltage (TOV)
- Surge with unexpected energy
MOV or SPD are protectors of Transient Overvoltage (or surge) but victims of Temporary Overvoltage.
