Vacuum Circuit Breakers and Contactors

<3 /6-VPR Series> < 10-VPR Series> <15-VPR Series> <20-VPR Series>

• Applying Mitsubishi Electric’s conventional vacuum valve technology as the basis, arc control technology and insulation design are leveraged to reduce size even further (i.e., 84% compared to conventional products) and increase reliability (E2 class).
• The self-cooling VCB eliminates the need to mount a fan on the panel for a wide rated current range, from 600A to 3150A.
• VCB has passed M2/E2/C2-class tests, ensuring high-quality standards compliant with IEC62271-100-2012.

*VI for 10-VPR-32D 1,250A

Exposure of hot components in the main circuit are minimized in VCBs with rated currents up to 3150A. This increases safety through prevention of potential hazards such as short-circuiting caused by the intrusion of small animals.

• Mechanical parts are coated with a long-life grease, helping to prevent oxidation and degradation, and lubricant-free bearings are used in the latch, thus extending the lubrication cycle for operational mechanisms from three years to six and reducing the time required for maintenance.
• VCB removal and insert operation features a new external drawer operation method that uses a cam-slide mechanism in addition to the conventional lever-based removal/insert operation method, thereby making removal/insertion easier, quicker, and safer.
• Enhanced options include an additional auxiliary switch and earthing switch.
• VCBs with rated currents up to 3150A can be shipped with the panel using shipping clamps.
• Can be easily exchanged with conventional model (10-VPR-C Series) mounting frame (same mounting hole positions, terminal/partition positions).

• Does not use any of the six specified hazardous substances (mercury, cadmium, lead, hexavalent chromium, polybrominated biphenyls, and polybrominated diphenyl ethers; under regulated values stipulated by RoHS in force since FY2006). Another example is, use of a rust-proofing treatment for small parts, such as pins and screws, that is free of hexavalent chromium (i.e., a substance known to contaminate soil).
• Recycling facilitated by displaying the names of materials used on major plastic parts.
