System Coordination Short-time ratings are high, giving users excellent system coordination and selectivity with downstream breakers. High Short-Circuit Current Ratings (SCCR) Up to 200 k AIR at 240 V, 150 k AIR at 480 V, and 100 k AIR at 600 V, which allows customers to design systems with high fault current and paralleling schemes. Arc Flash Limiting (LF) Feeder Breakers High speed operation of Masterpact MTZ, NW and NT circuit breakers (150 k AIR at 480 V) helps reduce arc flash incident energy (cal/cm2) on downstream equipment. Ease of Installation and Maintenance Thru-the-door construction, an easy to operate drawout mechanism, and front access to all control wiring make this equipment easy to install, maintain, and upgrade. Load connections in the cable compartment are easily accessible in the rear of the switchboard. Remote racking of the Masterpact circuit breaker is also available with the optional remote racking tool, which, if required, is field installable. Ability to Upgrade UL Listed, field-installable accessories include: motor operators, shunt trips, under voltage devices, trip units, and communication modules for trip units. Manually operated circuit breakers are field convertible to electrical operation. Open Communication System The Micrologic trip units in Masterpact circuit breakers use the Ethernet TCP/IP or Modbus™ serial protocol. These are widely accepted protocols which allow QED-6 to be integrated into new or many existing communication systems. Adaptable Drawout circuit breakers, front access control wiring, and expandable lineups are quickly adaptable to changing load and control requirements. Expandable Masterpact circuit breakers have many control termination points, giving the equipment extensive flexibility and expandability for sophisticated control schemes.
