Description
Cathtect USA gives integrity teams a modern toolset that legacy decouplers were never designed to support.
The SSD with Survey Isolation Switch is engineered for one purpose: deliver accurate survey data without compromising protection. Standard solid-state decouplers contain reactive elements that distort CIS/DCVG waveforms, forcing technicians to remove or bypass the device – an approach that introduces safety risks, increases survey time, and disrupts AC mitigation.
Cathtect’s survey-ready architecture solves this by isolating only the reactive components while keeping the DC protection path active. The result is a clean, undistorted waveform, continuous CP protection, and safer field operations.
The integrated switch is double-insulated, fault-rated, and designed with arc-diffusion chambers and venting to protect operators during actuation. Positioned at the test-station terminal board, it provides fast, safe access without handling live hardware.
Built on the same advanced filtering platform as the hazardous SSD and DCD, the SSD + Switch ensures stable AC mitigation, low impedance, and predictable performance – now with survey-optimized control.
