Mid Mounted Isolation Handcart is a modular isolation device specially designed for 40.5kV indoor high voltage systems. It integrates vacuum isolation fracture and handcart operating mechanism for fast electrical isolation and equipment maintenance. With 40kA short-time current tolerance , suitable for KYN series switchgear, support seamless insertion and removal operation, maintenance power outage time shortened by 60%. In line with GB/T 1984 and IEC 62271-100 standards, mechanical life of more than 10,000 times, protection level IP4X, suitable for substation, industrial and mining distribution and data center efficient power isolation scenarios, to provide "zero arc, zero risk" safe operation experience.

Mid Mounted Fuse Handcart Indoor High Voltage Circuit Breaker is an innovative mid mounted handcart switchgear with integrated fuse function, designed specifically for 40.5kV indoor high voltage systems. Adopting vacuum arc extinguishing technology and modular handcart structure, it has the ability to break 40kA short-circuit current, integrates high-voltage fuses to achieve dual protection against overload and short circuit, and saves 30% of cabinet space. Compliant with GB/T 1984 and IEC 62271-100 standards, with a mechanical lifespan of over 10000 cycles and a protection level of IP4X, it is compatible with KYN series switchgear and suitable for high-density and high reliability power scenarios such as industrial and mining power distribution, data centers, and rail transit. It provides an integrated "fuse arc extinguishing" safety solution.
