CI-50 50 Amp Current Interrupter

Description

The CI-50 50 Amp Current Interrupter from Tinker and Rasor is engineered for precision and performance in cathodic protection applications. This powerful interrupter allows accurate interruption of AC or DC rectifier output, enabling technicians to perform DCVG surveys, pipe-to-soil potential readings, and instant OFF measurements with confidence.

With a rugged MIL-SPEC locking enclosure, the CI-50 is built to withstand harsh environments while delivering repeatable results. This model improves on previous versions with increased portability, modern solid-state circuitry, and a high-contrast LED display for ease of use in the field.

Product Benefits

• Precision Interruption – Accurately programmable ON/OFF cycles from 0.1 to 99.9 seconds in 0.1s increments.
• Field-Ready Design – Battery-powered with up to 100 hours of runtime on 4 AA batteries.
• Memory Retention – Maintains your programmed settings, even when powered off.
• Easy to Use – Large LED display and visual OPEN/CLOSED indicators simplify operation.
• Compact & Secure – Lockable tan case provides internal cable storage and blends into outdoor environments to reduce heat absorption.
