CBA 3000 Circuit breaker analyzer

The ultimate all-in-one circuit breaker analyzer: safer, faster and more accurate than ever. It allows any timing test, motion and speed analysis, multiple contemporary static and dynamic contact resistance measurements, Both Sides Grounded (BSG) tests, Undervoltage condition test and more. All these functions are integrated in a single lightweight test case without the need of connecting additional external modules.

Manufacturer: ISA - ALTANOVA GROUP (Italy).

Description

CBA 3000 is also a up to six breaks micro-ohmmeter, it allows measuring the Static Contact Resistance (SCRM) of the circuit breaker contact and the Dynamic Contact Resistance (DCRM), that is how the breaker contacts resistances change while the breaker is closing or opening. This allows detecting hidden defects, that are otherwise impossible to be diagnosed.
