3. Product Features
- Modular Design: All functional units (circuit breakers, contactors, relays, measuring instruments, etc.) are standardized modules, enabling quick on-site assembly or replacement and significantly shortening the construction period.
- Rear-Mounted Busbar (MLS) Structure: Busbars are arranged at the rear of the cabinet, facilitating maintenance, reducing electromagnetic interference and providing better heat dissipation space.
- High Reliability: Adopts low-voltage switching components compliant with IEC 60947-4-1, with multiple protection functions including short-circuit, overload, under-voltage and under-current protection.
- Flexible Expansion: Modules can be added or reduced according to load requirements, realizing multi-level applications from main power distribution to sub-distribution.
- Compact Size: Smaller in volume and lighter in weight compared with traditional low-voltage switchgears, ideal for projects with limited space.
4. Structure & Composition
- Cabinet Body: Welded with high-strength steel plates, with reserved module installation slots inside.
- Rear-Mounted Busbar (MLS): Copper or aluminum busbars equipped with quick-connect buckles.
- Functional Modules: Including circuit breaker modules, contactor modules, relay modules, measuring instrument modules, communication modules, etc. Each module is configured with standardized terminals.
- Power Distribution Terminal Blocks: For external cable access, supporting screw or spring crimping.
- Protection Doors & Panels: Optional protection doors with indicator lights and operation buttons to meet on-site operation needs.
5. Typical Application Fields
- Industrial Plants: Main power distribution, sub-distribution and power supply for machinery and equipment.
- Commercial Buildings: Building power distribution, lighting and air conditioning system power supply.
- Energy Stations: Power distribution and control of photovoltaic, wind power and energy storage systems.
- Public Facilities: Places with high reliability requirements such as hospitals, schools and data centers.
6. Key Installation & Maintenance Points
Installation
- On-Site Survey: Confirm the space, ventilation and grounding conditions of the cabinet installation location.
- Foundation & Support: Reserve a solid ground foundation according to the cabinet weight, and use shock pads if necessary.
- Busbar Connection: Adopt dedicated quick buckles for rear-mounted busbar connection to ensure firmness and reliability.
- Module Assembly: Insert functional modules in sequence according to design drawings, and check whether slot buckles are in place.
- Wiring Inspection: All cable terminals must use compliant crimping or screw wiring to ensure good contact.
- Commissioning Test: Conduct insulation resistance and grounding continuity tests before power-on; perform short-circuit and overload protection function tests after power-on.
