PRIMA Series Primary Injection Test System

The PRIMA Series is a high-power primary injection test system designed for testing protection relays, molded-case circuit breakers (MCCBs), air circuit breakers (ACBs), CT circuits, and busbar systems.
With powerful output capacity, precise control, and rugged construction, the PRIMA Series delivers accurate, repeatable fault-level currents for commissioning, maintenance, and certification testing.

Key Features

  • High-capacity primary current injection up to several kilo-amps (model dependent)

  • Ideal for testing ACBs, MCCBs, CTs, relays, and busbar joints

  • Digital metering for current, time, and trip verification

  • Fast-rise output for accurate protection relay testing

  • Adjustable current control with fine/coarse settings

  • Built-in timer for over-current and trip timing tests

  • Short-duration and continuous output modes (per model)

  • Rugged trolley-type design for workshop or substation use

  • Thermal & overload protection for operator safety
