II. Environment and Supporting Parameters
- Control circuit power supply: AC220V/380V、 DC110V/DC220V
- Operating environment: Temperature - 10℃ ~ +40℃ , altitude ≤2000m , non-corrosive, non-explosive gases, relative humidity ≤85% No condensation
- Grounding system: TN-S、 TN-C-S Universal three-phase five-wire system
- The vertical busbar is encased in a flame-retardant insulating sheath to prevent phase-to-phase short circuits.
Application scenarios:
- Industrial park MCC Centralized motor control Start-up and shutdown, as well as overload protection, for water pumps, fans, compressors, production line conveyors, and dust collection equipment. / Short-circuit protection is the most critical application in factory workshops.
- Substation and plant auxiliary power systems Factory use 400V Incoming feeders, bus-tie switches, lighting circuits, cooling oil pumps, and fire‑fighting loads all require highly reliable power distribution.
- Commercial complexes, hospitals, data centers, and office building distribution rooms Central air conditioning, fire-fighting fans, sprinkler pumps, emergency power supplies, and general power load distribution—drawer‑type maintenance does not affect the power supply to other circuits.
- Chemical, metallurgical, wastewater treatment, and mining industries With a wide variety of load types and a large number of circuits, the modular drawer design enables rapid replacement of faulty units, minimizing downtime.
- Low-Voltage Grid-Connection and Collection Systems for Photovoltaic and Energy Storage Power Plants Integrated configuration for AC-side collection, power distribution, reactive power compensation, and metering & protection.
- Public power systems for rail transit, ports, and large pumping stations High-power load cluster management, optimized for long-term continuous operation.
Product Advantages:
1. Three independent metal compartments with strong fault isolation.
The cabinet body is rigorously partitioned by galvanized steel plates. Rear busbar compartment, front drawer function compartment, rear cable compartment Moreover, a short-circuit fire originating in a single drawer is confined to that compartment and does not spread laterally, resulting in significantly improved operational safety compared with conventional GCK switchgear.
2. 20 mm small module design, resulting in higher circuit density.
Compared with GCK’s 25 mm module, the same cabinet dimensions can accommodate more circuits; it supports drawers in multiple configurations—1/4, 1/2, and 1 unit—and allows flexible mixing of high- and low-current circuits, thereby reducing the footprint of the distribution room.
3. Four-position design plus mandatory mechanical interlocking to prevent misoperation.
The drawer is equipped with Work, testing, isolation, extraction Four operating positions; the drawer cannot be withdrawn when the circuit breaker is closed, and the circuit breaker cannot be closed unless the drawer is fully seated. The cabinet door and the operating mechanism are interlocked, mechanically preventing hazardous operations such as electric shock and plugging/unplugging under load.
4. Rotary propulsion mechanism, offering effortless operation and excellent interchangeability.
Knob‑type drawer‑push‑in mechanism ensures effortless insertion and removal while providing secure locking; drawers of the same specification are fully interchangeable, allowing for rapid on‑site repairs with just a spare unit, thus minimizing downtime during power outages. The vertical busbar is fitted with a flame‑retardant molded‑plastic sheath, further enhancing insulation safety and redundancy.
5. Rear-mounted main busbar with bidirectional outgoing wiring, offering flexible cable routing.
The main busbar is mounted on the rear side of the cabinet, and the cable compartment supports both top-in, bottom-out wiring configurations, accommodating various cable routing schemes in distribution rooms and facilitating on-site cable installation and connection.
6. Excellent intelligent adaptability, suitable for smart distribution network upgrades.
The drawer can house a multifunction meter, a current acquisition module, and a communication unit, enabling integration with PLCs and the substation’s backend monitoring system to support remote telemetry, remote signaling, fault reporting, and energy‑consumption analytics.
