Megger CB-845 Circuit Breaker Test Set

• Measurements: Output current (0-1200 A continuous, 5000 A instantaneous through 500 A breaker), time-delay characteristics (1 ms resolution), current transformer ratios. 

• Functionality: Tests molded-case breakers (up to 500 A), motor overload relays, ground-fault devices, digital memory ammeter (read-and-hold), multirange timer (crystal-controlled), solid-state output initiation, overload/short-circuit protection. 

• Design: Lightweight (80 kg total), two-section (control and output units), stackable metal enclosures (dimensions not specified), 208/240 V input (50/60 Hz), carrying handles, transportable by hand truck. 

• User-Friendly: Portable for confined spaces (e.g., shipboard, elevators), solid-state circuitry eliminates contact maintenance, digital metering for accuracy, protective lid for control unit, simple setup for field testing. 

• Complete Kit: CB-845 (50/60 Hz), timer leads (1.5 m), current leads (No. 4 1.5 m, 4/0 1.2 m), input connector (20 A), interconnect cable (1.2 m), fuses (0.125 A, 30 A), manual, one-year warranty, optional 3 m interconnect cable.

The Megger CB-845 Circuit Breaker Test Set is a lightweight (80 kg), portable, two-section system for testing molded-case circuit breakers (up to 500 A), motor overload relays, and ground-fault devices, delivering up to 1200 A continuous or 5000 A instantaneous output.

Featuring a digital memory ammeter, crystal-controlled multirange timer (1 ms resolution), and solid-state output initiation, it ensures high-accuracy testing with overload/short-circuit protection. Housed in stackable, rugged metal enclosures with a protective lid, it’s ideal for confined spaces like shipboard panels or elevator rooms, powered by 208/240 V (50/60 Hz).

The kit includes the CB-845, timer/current leads, input connector, interconnect cable, fuses, manual, one-year warranty, and an optional 3 m interconnect cable, perfect for field and industrial testing.
