DS40S DIN Rail AC Power Surge Suppressors

CITEL DS40S DIN Rail AC Power Surge Suppressors are UL1449 Type 1 and Type 4CA surge protection devices with a 40kA surge rating per module. The AC power surge suppressors operate within a -35°C to +60°C ambient temperature range and feature a modular construction with remote signaling, remote contacts, and a visual fault indicator. The DS40S devices from CITEL come with a ten-year warranty and are ideal for direct installation into critical equipment or within a nearby power panel.
