Thermal Protection MOV (TPMOV)/Surge Protective Devices (SPDs) – 1220 Series

Bourns' 1220 series SPDs are PCB-mounted TPMOVs which are surge suppressors with thermal protection designed to open in the event of overheating due to an abnormal overvoltage or temporary overvoltage (TOV) condition and will interrupt any abnormal current that may be encountered up to rated limits. These SPDs are intended to be installed at the front end of the installation, in the area of the main switchboard, close to sensitive terminals, or in installations without LPS (lightning protection systems, a.k.a. lightning rods). The model 1220 series are general-duty TPMOV SPDs with a maximum discharge current rating of 75 kA (8/20 μs). This series is UL-recognized and complies with UL 1449 and IEC 61643-11 standards.
