MasterPact UR

Description

Features
The worldwide benchmark for high current circuit breakers

MasterPact NW circuit breakers are equipped with MicroLogic control units that offer built-in power and energy metering in addition to basic or advanced protection functions. Two sizes are sufficient to cover applications from 800 to 6300 A, with a breaking capacity from 42 to 150 kA.
The range comes with a wide choice of standardized accessories. The universal design of the MasterPact circuit breaker line allows most accessories to be used across the entire line. It enables the standardization of electrical switchboards by providing peace of mind in terms of choice, installation, and operation.

Benefits
MasterPact NW circuit breakers contribute to the reliability and continuity of service of your electrical installation thanks to the:

Optimized safety

Faultless protection
Increased uptime with improved coordination with MicroLogic electronic trip unit adjustability
Complete selectivity and coordination
High resistance to environmental stresses
Integrated monitoring for energy efficiency

Improved uptime with a complete monitoring solution in Smart Panels
Seamless integration into power monitoring systems enables to track of energy consumption trends, anticipate potential damage and improve network reliability

Local and remote communication with trip cause (earth leakage, overload, short-circuit) and alarms (earth leakage, overload) allow proactive operational and energy efficiency
Advanced MicroLogic control unit can assist in providing corrective, preventive, and predictive maintenance, and energy management to identify potential savings: energy consumption data, operation follow-up, network monitoring, preventative and predictive maintenance information, pre-alarm and alarm events
