Power distribution and selective protective coordination
To guarantee uninterrupted power to critical plant machinery, CHINT supplies a comprehensive line of distribution switchgear, ranging from NB1-63 modular miniature breakers to NA1 heavy-duty air circuit breakers up to 6300 A.
Microprocessor trip controllers with configurable short-time delay thresholds enable comprehensive zone-selective interlocking throughout the facility.
When a localized fault occurs on an outgoing sub-feeder, only the relevant branch breaker trips, allowing the main incoming breaker to sustain power across remaining production areas, thereby preventing costly unplanned facility shutdowns.
