Product catalog summary
Introduction
The document introduces the VPR Series Vacuum Circuit Breakers by Mitsubishi Electric, highlighting their advanced technology and safety features, designed to meet future needs with enhanced environmental and maintenance measures.
Specifications
The VPR Series features Mitsubishi Electric's vacuum interrupter technology, resulting in a compact design that is 16% smaller than previous models. These self-cooling circuit breakers support rated currents from 600 to 3,150A, comply with IEC 62271-100-2012 standards, and have passed type tests for classes M2, E2, and C2, ensuring high reliability and safety.
Safety and Environmental Measures
Safety is enhanced by minimizing exposure to live parts, even in high-rated models, to prevent hazards. Mechanical parts are coated with long-life grease, extending the lubrication cycle from three to six years. The circuit breakers exceed RoHS standards by being free from six hazardous substances and use rust-proof treatments free of hexavalent chromium.
Design and Operation
The VPR Series includes a new withdrawable mechanism with a door-closed option, reducing operating effort and enhancing safety. It offers options for additional auxiliary and earthing switches and is compatible with previous series mounting frames for easy integration.
Technical Information
Advanced technologies like 3D CAD and CAE ensure reliability and safety. The vacuum interrupters are optimized for size and performance, with a 16% size reduction. The document details the VCB structure, operation mechanisms, and thermal fluid analysis for efficient heat release.
Standards and Testing
The document outlines mechanical and electrical endurance classifications according to IEC standards, with tables showing operating sequences for classes M1, M2, E1, and E2. It describes the probability of arc restrike during capacitive current switching tests, with class C2 being highly reliable.
Conclusion
The VPR Series Vacuum Circuit Breakers offer advanced technology, high reliability, and enhanced safety features, making them suitable for future electrical engineering needs.
Mounting and Installation
The document details components and installation requirements, including mounting screws, side-lock plates, and insertion holes. A φ5mm unlocking pin is required for operation, with specific dimensions provided for installation.
Capacitor Tripping Device (CTD)
The CTD allows remote tripping of the circuit breaker without control power, essential for operation under power loss conditions.
Operation Mechanism
The operation mechanism involves a control circuit managing the closing and tripping of the circuit breaker, with detailed diagrams and tables outlining control voltage, current requirements, and timing for AC and DC operations.
Control Circuit Diagrams
Figures illustrate the basic control circuit, showing the state of the circuit breaker, motor circuit, and operation sequence for closing and tripping, highlighting components like limit switches, auxiliary relays, and coils.
Technical Specifications
Tables provide detailed specifications for control voltages, current flow times, and operational ratings, crucial for correct setup and operation.
Surge Protection and Standards
The document discusses surge protection devices and compliance with standards like JEC-2300 and IEC 62271-100, emphasizing adherence to prevent damage and ensure reliable operation.
Operating Environment
Normal service conditions are specified, including temperature, humidity, and pollution levels, with precautions for installation sites to avoid excessive dust, corrosive gases, and vibrations.
Service Life and Maintenance
The service life of the VCBs is specified at 10,000 operations for mechanical and load switching service life. Regular maintenance and inspections are recommended to ensure longevity and performance.
