Megger CB-360-DC DC Circuit Breaker Test Set

• Measurements: DC output current (0-30,000 A, ±5% full scale), time-delay characteristics (seconds/cycles, ±0.0025% or ±0.5 cycle), breaker trip time. 

• Functionality: Tests low-voltage DC circuit breakers, calibrates electromechanical/thermal-magnetic trip devices, digital timer (crystal-controlled), timer control circuit (current-actuated, normally open/closed modes), forced-air cooling, overload/short-circuit protection, stab adapter board for drawout breakers. 

• Design: Two-piece enclosure (control: 663 kg, output: 720 kg), 114 x 135 x 76 cm each, 460 V 60/50 Hz or 380 V 50 Hz input, locking casters, lifting eyebolts, temperature-sensitive interlock, rugged for mobility. 

• User-Friendly: Switch-selected timer modes, high-accuracy digital timer with noise suppression, direct stab connections (CBS-1/CBS-2), portable for field use, simple setup for overload/fault simulation. 

• Complete Kit: CB-360-DC (460 V or 380 V), CBS-1/CBS-2 stab sets, continuity/timer leads (3.7 m), input leads (4.5 m), ground interconnect, interconnect cables, lifting eyebolts, fuses (1.0/1.5/3.0 A), manual, one-year warranty, optional CBS-3 stab set.

The Megger CB-360-DC DC Circuit Breaker Test Set is a mobile, high-current system designed for testing low-voltage DC circuit breakers, delivering up to 30,000 A to calibrate electromechanical or thermal-magnetic trip devices by simulating overload/fault conditions.

It features a crystal-controlled digital timer (±0.0025% or ±0.5 cycle accuracy), switch-selected timer modes (current-actuated, normally open/closed), and a stab adapter board with CBS-1/CBS-2 sets for drawout breakers. Housed in two rugged enclosures (663 kg control, 720 kg output, 114 x 135 x 76 cm each) with locking casters and forced-air cooling, it operates on 460 V (60/50 Hz) or 380 V (50 Hz) input, with overload protection and a temperature interlock.

The kit includes the CB-360-DC, stab sets, leads, interconnect cables, fuses, manual, one-year warranty, and an optional CBS-3 stab set, ideal for precise field testing in industrial settings.
