When the temperature reduces, the PolySwitch resets to resume normal operation. No manual resetting is required. Can be used to protect batteries, power supplies, motors transformers, speakers, AC/DC, etc. The following characteristics are for DC in still air at 20°C. For AC use Ohms Law and a mean value for ITRIP & IHOLD (Remember the RMS!) Varistor MOV PTC METAL OXIDE VARISTOR SHARP Original part as used in Sharp appliances. Code VX0010 Transorbs TRANSORBS DEVICES TRANSIENT VOLTAGE SUPPRESSORS AKA; Transient absorption or suppressor diode, Avalanche diode, Series Protection Diode, etc. Designed specifically to protect sensitive electronics equipment from voltage transients induced by lightning and other transient voltage events. These devices are ideal for the protection of I/O interfaces, Vcc bus and other vulnerable circuits used in automotive, industrial and consumer electronic applications. MOSORB BI-DIRECTIONAL 1.5KW HI-TECH VARISTORS VDR MOV APPLICATIONS: Surge protection in Consumer electronics Industrial electronics Telephone equipment Telecommunications Automotive instruments control and ignition systems. Measurement and control Gas & Petroleum Equipment Appliances, etc., etc. Absorption of switching surges for relays, switches, etc. Electro-static discharge Noise suppression specific component protection transistors, triacs, ICs, etc. METAL OXIDE VARISTORS Zinc Oxide Voltage Dependent Resistors. Fast, Low-Leak MOVs. High Performance. Protects from Over-Voltage, Spikes, etc. Joules are now based on 10/1000μS waveform. Imax is now based on a 10/1000μS waveform.
