VOLTALUME VL-MCCB-M8 Series Molded Case Circuit Breaker — New-generation protection engineered for power distribution and motor circuits at scale.
The VOLTALUME VL-MCCB-M8 is a new-generation molded case circuit breaker built on advanced international design principles, rated insulation voltage 800–1000V and operating up to 690V, with current ratings from 125A to 1250A. It provides overload, short-circuit, and undervoltage protection for power distribution lines and equipment, plus AC-3 motor protection for infrequent starting duty. Offered in three breaking-capacity tiers — C (standard), L (high breaking), and M (highest breaking) — it gives specifiers a single series that scales from light commercial boards to heavy industrial mains.
Key Features
- Full frame range: 125A through 1250A in one series
- Three breaking-capacity tiers: C (standard), L (high), M (highest — up to 100kA at 400V)
- 2/3/4-pole configurations depending on frame and tier
- Compact footprint, short arcing time, vibration-resistant construction
- GB/T 14048.2 / IEC 60947-2 compliant
