Product features

The cabinet adopts a modular assembled structure,
while the circuit breaker features a handcart-mounted floor design.
Integrated with a new composite insulated vacuum circuit breaker,
offering excellent interchangeability and easy replacement.
The handcart frame includes a screw-nut drive mechanism,
enabling smooth movement and protecting the drive system from misoperation damage.
All operations can be performed with the cabinet door closed,
enhancing safety during use.
The system employs a mechanical interlock between the main switch,
handcart, and the cabinet door to ensure full compliance with
The "Five Prevention" safety functions.
Ample internal space is provided for convenient cable connection.
A quick-action grounding switch is used to ensure safe grounding
and circuit shorting where necessary.
The enclosure meets IP3X protection standards.
when the handcart door is open, the protection level remains at IP2X.
Designed and manufactured in full compliance with GB3906, DL404,
and international IEC 298 standards.
