Low voltage Motor Control Center (MCC) drawer operating mechanisms manufactured by
Richge Technology are the key components in the power distribution. The drawer
mechanism has high adaptability, divided into functional units listed as input feeders, output
feeders and motor controllers; Modular configuration to meet the electrical load requirements.
These mechanisms are designed to be adaptable and divided into functional units such as
input feeders, output feeders and motor controllers, allowing modular configuration to meet
different electrical load requirements.
Low-voltage MCC drawer operating mechanism functions as follows:
Push-in and pull-out: Push the drawer to insert into the fixed position (Connection position)
in the switchgear and pulled out from the fixed position ( isolation position or test position), so
that the drawer can be switched between different working states. When inspect or maintain
the electrical components in the drawer, the drawer can be moved out to the isolation position
to ensure the maintenance safety.
Position locking function: When drawer in connection/test/ isolation, it can lock the drawer in
the corresponding position to prevent the drawer moving with power.Complies with the
principle of safe operation and avoids safety accidents caused by misoperation.
Safety features
Mechanical interlock system: ensures the drawer cannot be withdrawn when powered, to
prevent accidental contact with charged components. Isolation contacts: automatically
disconnect power when plugged in/out, eliminating arc flash risk (compliant with IEC 61439
standard) Effective maintenance, faulty drawers can be quickly replaced (under power-off
conditions) via hot-swap functionality, minimizing downtime. This plug-and-play design
supports seamless maintenance without interrupting adjacent circuits.
Standardized current ratings: Drawers are categorized by current capacity (63A, 125A, 250A)
to ensure compatibility with different loads.
