Low Voltage Motor Control Center
The XL-21 low voltage motor control center provides a high-performance packaging solution for all your motor control needs. It is suitable for 3-phase 3-wire, 3-phase 4-wire, and 3-phase 5-wire applications up to 500V AC.
The frame is constructed via steel plate bending and angle steel welding and a variety of meter equipment can be installed on the cabinet door such as voltmeters, ammeters, power monitors, and more. Opening the cabinet door, all its inner components are accessible, making inspection and maintenance easy if this equipment is installed correctly against a wall. There are neutral bonding screws designed inside the enclosure and cabinet doors to ensure operator safety.
