CEM DT-5301 LOOP/PSC Tester

The CEM DT-5301 Loop/PSC Tester is a specialized device designed for testing electrical loop impedance and prospective short circuit (PSC) currents in electrical circuits. This type of tester is crucial for electricians and technicians who need to ensure that electrical installations have adequate fault protection and are safe to use.

The LOOP testing function of the DT-5301 helps measure the total impedance of a live-to-earth loop path, which is key to verifying that circuit breakers or fuses will operate correctly under fault conditions. PSC testing, on the other hand, measures the maximum current that can flow in the event of a short circuit, assessing the capacity of the installation to handle such extreme conditions safely.

CEM DT-5301 Key Features
