Power-Zone 4 LV drawout switchgear offers proven, reliable and durable switchgear that is required for Critical Power applications. With Masterpact NW UL1066 Listed circuit breakers, Power-Zone 4 LV drawout switchgear is the equipment of choice by consultants and end customers in the following markets:

• Telecommunications Facilities

• Data Centers

• Continuous Process Manufacturing Plants

• Critical Care Facilities

Power-Zone 4 switchgear is designed as a standalone or as an integral part of the low voltage equipment lineup in a user's power unit substation. This switchgear should be used for critical power applications because:

• Drawout construction is required for quick circuit breaker change-out

• System requirements call for circuit breakers to close within 5-cycles

• Stored energy circuit breakers are required for reliability

• Front access to control wires is desired for ease of installation, maintenance, and upgrade

• Circuit breaker compartmentalization is required for system integrity

• Segregation of circuit breaker compartments from bus and cable compartments is required for equipment

• Isolation breakers without fuses are required for high short circuit current ratings up to 200kAIR

Major benefits:

• Small, flexible footprint

• Extended maintenance intervals

• Segregated access to all wiring

• Easily added 'smart' functionality, such as communications interfaces and power monitoring and control capability

• Available up to 5000A bus rating

• Micrologic®  trip units with power monitoring, control an communications

• Optional PLC based auto transfer schemes

• Optional Transparent Ready™  communications utilizing PowerLogic®

• Optional Surgelogic®  TVSS

• Differential ground fault option for 4W systems with multiple sources

• Arc flash application options:

  • Arc flash limiting feeder breakers up to 2000A reduce arc incident energy on downstream equipment such as UPS and PDPs

  • Thru-the-door breaker operation allows unit to be operated or tracked while door is closed, reducing NFPA 70E PPE category by one level

  • Rear-hinged doors allow easy access to cables, reducing NFPA 70E PPE category by one level

Features of Power-Zone 4 switchgear with Masterpact NT/NW circuit breakers:

• Switchgear ratings up to 200kA without fused circuit breakers

• Short circuit current rating for services 1600A to 5000A

• Thru-the-door breaker operation

• Front access to all control and communication wiring

• Up to eight 800A frame Masterpact NT circuit breakers in a single 30-in. wide section

• Micrologic  trip units with Modbus®  RTU communications

• Micrologic trip units that are field replaceable and upgradeablebe

• Masterpact NW/NT circuit breakers that are maintainable and serviceable

Data center applications:

• Main service switchgear

• Paralleling switchgear

• UPS input switchgear

• UPS output switchgear

• Load bank switchgear

Benefits of using in data center applications: 

• Drawout construction is required for quick circuit breaker change-out

• Transfer system requirements call for circuit breakers to close within 5-cycles and stored energy circuit breakers are required for reliability

• Front access to control wires is desired for ease of installation, maintenance and upgrade

• Circuit breaker compartmentalization is required for system integrity

• Segregation of circuit breaker compartments, from bus and cable compartments, is required for equipment
