Masterpact® NT Series Circuit Breaker
The Masterpact NT Circuit Breaker is the latest addition to the Masterpact circuit breaker line. It is a fully tested, full-featured power circuit breaker in the smallest footprint available on the market today—70% smaller than the Masterpact NW circuit breaker. The Masterpact NT Circuit Breaker (800 to 1600 A) is designed to protect electrical systems from damage caused by overloads, short circuits and equipment ground faults. It incorporates the latest advances in breaker technology including:
- Selection of four interchangeable Micrologic® Trip Units with PowerLogic® power metering communications and monitoring capabilities.
- Field-installable devices (without circuit breaker adjustment) including trip units, sensor plugs and most accessories.
- Drawout breakers with four racking positions (connected, test, disconnected and removed) with status indicator on cradle.
The Masterpact NT Circuit Breaker is manufactured and tested in accordance with UL 489, UL 1066, ANSI and IEC 60947-2 standards, providing customers with unmatched application flexibility.
