Product Description
INTRODUCTION
Power-Zone
®
4 low voltage, metal-enclosed, drawout switchgear is designed to provide superior
electrical distribution, protection, and power quality management for the entire facility. The prime
components of the switchgear are the Masterpact
®
NW and Masterpact NT ANSI-rated circuit
breakers. Power-Zone 4 switchgear is designed to maximize the functionality of the Masterpact NW
and NT circuit breakers, which, in turn, deliver maximum uptime, system selectivity, ease of
maintenance and circuit protection. All of this in the smallest footprint available for low voltage drawout
switchgear.
