TST Series
Commercial & Light Industrial DIN-Mounted SPD
The TST Series of SPDs (surge protection devices) are designed to protect sensitive electronic equipment from the harmful effects of transients.
Models are configured for both parallel or series installation and can be either din rail or wall mounted. Units are rated as Type 2 SPDs component assembly making the TST Series the ideal choice for incorporation into control cabinets for sensitive microelectronic based equipment.
TST units are self-contained in rugged plastic enclosures and use twenty millimeter (20mm) MOVs as their key suppression elements. Units are not line load sensitive and interface with the incoming power cables via screw terminals (barrier strips):
Small Terminals are capable of handling #14 to #30 AWG Wire.
Large Terminals are capable of handling #6 to #20 AWG Wire.
