The KACHAI 800A incoming cabinet adopts an electronic molded case circuit breaker (MCCB) as the main control switch with comprehensive protection functions. It provides three-stage protection: long-time delay against overload, short-time delay for short-circuit faults, and instantaneous short-circuit protection. Precise protection parameter calibration prevents unwanted tripping due to fault coordination mismatch. Fitted with current transformers and a multi-function meter, the cabinet enables real-time monitoring of voltage, current and power, alongside accurate total power consumption calculation. It delivers user-friendly operation and enhanced maintenance safety. Equipped with the ASJ series residual current operated relay, the device provides residual current protection for electrical circuits, preventing equipment damage and electrical accidents triggered by residual current, while offering indirect contact protection against personal electric shock hazards.
Accurate Metering & Monitoring for the Whole Station
Standardly equipped with current transformers and a multi-functional power meter, it monitors three-phase voltage, current and power metrics in real time and tallies total power consumption precisely. It facilitates on-site load management and energy consumption statistics, supports extended communication connection to central control systems, and complies with standardized power distribution operation and maintenance requirements.
Centralized Power Control for Efficient & Safe Maintenance
Serving as the general inlet of busbars, full power cut-off for station-wide maintenance can be completed simply by switching off the incoming cabinet. The intuitive operation cuts down safety risks and streamlines routine inspection and equipment maintenance procedures significantly.
A fixed full-coverage acrylic protective baffle comes as standard, isolating all live internal components. It thoroughly rules out electric shock risks caused by accidental hand contact during patrol inspection, operation and cleaning, complying with factory workplace safety codes.
Convection Cooling Design Prevents Overheating During Long-Term Operation
Dedicated air intake and exhaust openings are reserved on the cabinet to create natural air convection, rapidly dissipating heat generated by switches and components. This avoids excessive temperature buildup under continuous operation and greatly improves equipment operational stability.
Full Stainless Steel Body with 120μm Fine Spraying Coating
Constructed entirely of stainless steel and finished with a 120μm electrostatic spraying process, the cabinet features outstanding rustproof, moisture-proof, dustproof and impact-resistant performance. It is well suited for harsh workshop environments with heavy dust, high humidity and drastic temperature fluctuations, offering superior durability and extended service life.
Internal wiring strictly complies with electrical codes with clearly zoned and neatly arranged cables. It greatly simplifies fault troubleshooting, shortens time spent on wiring modification and maintenance, and cuts enterprises’ long-term operation and maintenance costs effectively.
