ОПИСАНИЕ ПРОДУКТА
SCHNEIDER ELECTRIC LTMCU - TeSys U Standard Control Unit
The SCHNEIDER ELECTRIC LTMCU is a standard control unit designed for integration with the TeSys U modular motor starter system. It provides essential motor protection functionalities, including thermal overload, short-circuit, and phase imbalance detection, directly interfacing with the TeSys U power base. This unit delivers fundamental control logic and status feedback for direct-on-line motor starting and protection across diverse industrial automation and process control applications.
Technical Specifications:
- SERIES/FAMILY: TeSys U
- COMPONENT TYPE: Standard Motor Control Unit
- ELECTRICAL SPECS:
- CONTROL CIRCUIT VOLTAGE: Operates on control voltage supplied to the TeSys U power base (e.g., 24VDC, 48VDC, 110-240VAC, variant-dependent).
- MOTOR CURRENT MONITORING: Monitors motor current range as defined by the associated TeSys U power base (e.g., 0.15A to 32A, variant-dependent).
- PROTECTION FUNCTIONS: Thermal overload (Class 10), short-circuit, phase loss, phase imbalance.
