Megger DDA-3000 and DDA-6000 Universal Circuit Breaker

• Measurements: Output current (up to 35,000 A for DDA-3000, 60,000 A for DDA-6000, ±1-2%), breaker trip time (seconds/cycles, ±1%), input/output voltage (up to 600 V, ±1%), contact voltage drop. 

• Functionality: Tests low-voltage molded-case/metal-clad breakers (3000/6000 A), DDA-1 module with DSP for precise SCR control, digital ammeter (true RMS/peak), timer (auto-start/stop), voltmeter, pulsed/maintained modes, zero DC offset, series connection for high-impedance, CT ratio verification, relay testing. 

• Design: Single enclosure (454 kg DDA-3000, 545 kg DDA-6000), 117 x 117-140 x 71 cm, rugged with casters, tow ring, lifting eyes, 460/380/415/575 V input, forced-air cooled SCRs, ground interlock, 120 V outlet, NEMA AB-4 compliant. 

• User-Friendly: Compact for maneuverability, digital interface with soft buttons, automatic timing for various breakers, panel indicators (energized, thermal, ground), remote initiation, programmable pulse duration, high-accuracy metering. 

• Complete Kit: DDA-3000/6000, input leads (4.5 m), output leads (1.5 m), timer leads (3.7 m), ground lead (0.45 m), interconnect cables, fuses (0.25-5 A), manual, CBS-1/CBS-2 stab adapters, one-year warranty, optional protective cover, AF-1/AF-4 autotransformer.

The Megger DDA-3000 and DDA-6000 Universal Circuit Breaker Test Sets are rugged, high-capacity systems for testing low-voltage molded-case and metal-clad circuit breakers up to 3000 A (DDA-3000) or 6000 A (DDA-6000), delivering up to 35,000 A or 60,000 A, respectively.

Equipped with the DDA-1 module using DSP, they ensure precise SCR control, zero DC offset, and accurate measurements of current (±1-2%), trip time (±1%), and voltage (±1%). Compliant with NEMA AB-4, they support pulsed/maintained modes, series connection for high-impedance devices, and applications like CT ratio verification and relay testing.

Housed in a compact, maneuverable enclosure (454-545 kg) with safety features like ground interlock and forced-air cooling, the kit includes the test set, leads, stab adapters (CBS-1/CBS-2), fuses, manual, one-year warranty, and optional accessories (protective cover, AF-1/AF-4 autotransformer), ideal for industrial and utility breaker testing.
