By the trend of harminization of Japanese electrical facility standards with the leading international standards, new JIS standards for DC high-speed circuit breaker (HSCB) was drafted by combining the elements of JEC and IEC standards.
We offer large capacity, compact and lightweight ML type HSCB (with permanent magnetic Magnet Latch) - JIS E 2501 (H1 type) compliant model.
It has a safety feature like mechanical interlock to prevent the draw-out work while the switch is at "Close" mode. And during the circuit breaking, it has a mechanism of not releasing arc to the outside.

• It complies with the latest JIS standard (JIS E 2501 -Type H1).
• Large capacity: Maximum rated current 6000 A
• High interruption performance: Rated short-circuit current 100 kA
• Compact and lightweight: Main unit weight comparison 82% (compared with previous model)
• Downsized cubicle storage: Installation area comparison 50% (compared with previous model)
• Simple and highly reliable structure
  - Permanent magnet holding type
  - Solenoid operation type
• The arcing contactless design realizes long operational life by interrupting only at the main contact.
