DW45 Series
DW45 Intelligent Air Circuit Breaker (ACB)
Why choose ZY POWER for this project
Main LV protection device
DW45 is suitable for high-current incoming and bus-coupler circuits where reliable tripping and maintainable panel integration are required.
Fixed or drawout installation
The breaker can be configured for fixed mounting or drawout cradle installation according to the switchboard maintenance concept.
Trip unit options by project
Protection functions, metering, alarms, auxiliary contacts and communication options can be selected according to the electrical scheme.
LV switchboard integration
Busbar interface, cabinet depth, operating handle and interlocking should be coordinated with GGD, GCS, GCK or MNS panel design.
DW45 series intelligent air circuit breaker (ACB) rated 630A, 3P, 400/690V AC, breaking capacity 65kA. Microprocessor-based trip unit with LCD display, LSIG-N protection, Modbus communication optional. Draw-out and fixed mounting available. IEC 60947-2 certified for main distribution protection.

Request evidence packageDW45 air circuit breaker is used as the main incoming, bus coupler or high-current feeder protection device in low-voltage switchboards. It is usually selected for transformer secondary distribution, industrial LV rooms, commercial buildings and generator or utility incomer panels. Procurement should confirm frame size, rated current, breaking capacity, pole number, fixed or drawout type, trip unit functions, control voltage and communication requirements.
What Buyers Should Confirm
- Rated current, frame size, breaking capacity, pole number and installation type.
- Trip unit functions, control voltage, auxiliary contacts and communication requirement.
- Switchboard type, busbar connection direction, cabinet layout and interlocking requirement.
- Routine test scope, wiring diagram, packing method and spare accessory list.
