There are three positions for connection, testing, and extraction: the connection position provides normal power supply; The main circuit of the test site is powered off and the secondary circuit is powered on, which can be safely debugged; Pull out the position and completely physically disconnect, forming a visible power outage breakpoint.
After extraction, there is a clearly visible insulation gap, and there is no risk of electric shock or misoperation during maintenance, meeting electrical safety regulations.
Without dismantling the main and secondary cables, the circuit breaker body can be directly removed for maintenance and replacement without damaging the cabinet wiring.
Only when the circuit breaker is opened can it be pulled in and out, and the connection cabinet door cannot be opened to avoid load insertion and accidental contact with live parts structurally.
Integrate auxiliary contacts, shunt/undervoltage trip and other accessories, unify the transfer of main circuit and secondary line, simplify cabinet wiring.

The drawer base features three distinct positions: Connection (provides normal power supply), Test (disconnects the main circuit while keeping the secondary circuit powered for safe debugging), and Extraction (completely physically disconnects the unit to form a visible safety breakpoint).
It provides visible isolation breakpoints and mechanical interlocks. This ensures that the circuit breaker can only be inserted or extracted when it is fully opened, preventing accidental contact with live parts and eliminating the risk of electric shock.
No. The design allows you to directly remove and replace the circuit breaker body without dismantling the main and secondary cables, protecting the cabinet wiring from damage and saving valuable time.
By using the modular plug-in design, the replacement time for a circuit breaker is reduced from several hours (required for standard fixed wiring) to just over ten minutes.
Yes, they are designed with modular universality. Circuit breakers of the same specifications are interchangeable, simplifying spare parts management and allowing flexible system expansion or renovation.
They are ideal for critical power environments such as data centers, industrial manufacturing facilities, and commercial infrastructure where minimizing power downtime and ensuring rapid maintenance is essential.
