Product catalog summary

Overview: This document provides technical specifications and solutions for Schneider Electric's Masterpact NT and NW low voltage power circuit breakers, ranging from 630 to 6300 A. It highlights the features, applications, and benefits of these circuit breakers in various industrial and commercial settings.

Specifications: The Masterpact circuit breakers are designed for high electrical endurance applications, offering high breaking capacity and discrimination in a compact form. They are suitable for a wide range of applications, including mines, direct current networks, and emergency power systems. The document details the rated insulation voltage, impulse withstand voltage, and operational voltage, along with sensor ratings and circuit breaker characteristics as per IEC and NEMA standards.

Procedures and Solutions: Schneider Electric offers a 'Plug and Play' retrofit solution that allows for quick and simple implementation with minimal on-site intervention. The retrofit uses a factory-modified Masterpact NW installed in the original Masterpact M chassis, reducing installation time to 30 minutes with two easy operations.

Monitoring and Protection: All Masterpact units are equipped with Micrologic electronic control units, providing advanced protection, measurement, and communication capabilities. These units ensure safety and reliability by separating protection functions from measurement functions, managed by an ASIC electronic component.

Network Integration: Masterpact can be integrated into a general supervision system to optimize electrical installations. When equipped with Micrologic type P, it can be connected to PowerLogic ION Enterprise software for enhanced energy management, reducing costs, improving power quality, and optimizing equipment use.

Applications: The document outlines the suitability of Masterpact circuit breakers for various sectors, including buildings, data centers, industry, energy, and infrastructures. It emphasizes the importance of continuity of service in critical power applications and the role of automatic transfer switching equipment (ATSE) in ensuring reliable power source management.

Key Features: The Masterpact UR circuit breaker is highlighted for its ultra-rapid opening capability, crucial for installations with high short circuit currents. The document also details the characteristics of circuit breakers and switch-disconnectors, including their mechanical and electrical durability, rated making capacity, and short-time withstand current.

Standards and Compliance: The products comply with international standards such as IEC 60947-1, IEC 60947-2, IEC 68230, UL489, ANSI/UL1066, CCC, and GOST. The document highlights the environmental compliance of the production facilities with ISO 14001 standards.

Recommendations: Recommendations include consulting for specific ratings like NT02 and NW02, and ensuring external protection complies with thermal constraints. The document suggests using the Masterpact range for standardizing electrical switchboards to simplify installations.

Key Data from Tables: The tables provide detailed data on rated making capacity, short-time withstand current, and service life cycles for different models. For example, the rated making capacity for NW models ranges from 88 kA to 330 kA peak, and the rated short-time withstand current varies from 42 kA to 100 kA rms.

Environmental and Safety Features: The document emphasizes the environmental friendliness of the materials used, which are recyclable and non-polluting. Safety features include arc chutes that absorb energy during breaking, reducing external effects and ensuring maximum security.

Critical Information: The document emphasizes the importance of adhering to specified standards and procedures to ensure safety and reliability. It highlights the need for external protection to comply with thermal constraints and the absence of fault-trip indication by the SDE or reset button.

Monitoring and protecting your low voltage network Masterpact can be integrated in a general supervision system to optimise your electrical installation. Covering all your applications Masterpact provides an answer to specific applications. 1000 V for mines Direct current networks Corrosion protection Switch-disconnectors and earthing switches Automatic transfer switching equipment (ATSE) for emergency power systems High electrical endurance applications: Masterpact NT H2 is a high performance device offering high breaking capacity (Icu: 50 kA/480 V) and a high level of discrimination, all in a small volume. @ @ @ @ @ @ Ensuring safety at any time All Masterpact are equipped with a Micrologic electronic control unit that offers all types of current and advanced protection, measurement and communication. Protection functions are separated from the measurement functions and are managed by an ASIC electronic component. This independence guarantees immunity from conducted or radiated disturbances and ensures the highest degree of reliability. Optimising the management of your electrical installation When equipped with a Micrologic type P, Masterpact can be integrated in a general supervision system to optimise installation operation and maintenance. Alarms may be programmed for remote indications. Used with PowerLogic ION Enterprise software, you can exploit the electrical data (current, voltage, frequency, power, and power quality) to optimise continuity of service and energy management: reduce energy and operations costs; improve power quality, reliability and uptime; optimise equipment use. Maximising continuity of service Because a LV power supply interruption is unacceptable especially in critical power applications, an automatic system is required for LV transfer switching. For your peace of mind, Masterpact enables automatic control and management of power sources in your low voltage distribution network guaranteeing the hi-reliability of your installation. @ @ @ EGX400 The EGX400 server is used as an Ethernet coupler for the PowerLogic System devices and for any other communicating devices operating under the Modbus RS 485 protocol. PowerLogic ION Enterprise PowerLogic ION Enterprise software is a complete power management solution for your facility or plant operations. It can be connected to Masterpact through Ethernet/Modbus protocol. Masterpact meets the needs of all types of LV electrical distribution networks. Whenever high short circuit is involved Masterpact UR is a low voltage ultra rapid opening circuit breaker. Its fault detection rate and its reaction speed mean that it will stop a short circuit from developing. As a result, this is the key component in very high power installations equipped with a number of power sources connected in parallel. Masterpact UR truly comes into its own when short circuit currents can reach very high levels and when continuity of service is a must: offshore installations, cement plants, petrochemical industry. It is also especially suited to electrical installations on board merchant ships.
