This is a heavy-duty industrial wire harness featuring a thick black PVC outer sheath main cable that splits into multiple branch leads at one end. The branch wires terminate with two distinct connector types: green pluggable screw terminal block connectors (PCB-mount compatible) for secure, tool-assisted field wiring, and red insulated female spade (faston) connectors for quick plug-on connections to blade terminals on switches, relays, or power devices.
The black outer jacket provides mechanical protection and bundling for the main cable run, while the individual color-coded inner conductors — blue and brown visible in the image, following standard IEC color conventions for neutral and live — ensure compliance with recognized wiring standards and simplify inspection.
The pluggable terminal block connectors allow field engineers to insert and secure wires via screw clamping without soldering, making installation, replacement, and maintenance straightforward in panel-mounted equipment. The combination of rigid terminal block outputs and quick-connect spade outputs in a single harness makes this design well-suited for equipment that integrates both PCB-level and device-level power distribution in one wiring run.

3. Application Scenarios
Industrial Control Panels & Distribution Boards The pluggable terminal block ends connect directly to PCB-mounted or DIN rail-mounted terminal strips inside control panels, while the spade connectors interface with circuit breakers, contactors, and selector switches — making this harness a complete panel-to-device wiring solution in a single assembly.
HVAC & Building Automation Equipment Used inside air handling units, chillers, and building automation controllers where a main power feed must be distributed to multiple sub-assemblies including sensor boards, relay modules, and actuator terminals in a structured, maintainable way.
Solar Inverters & Energy Storage Systems Connects AC output terminals on inverters or battery systems to pluggable PCB terminal blocks for monitoring circuits and to spade terminals on protection devices such as fuses, breakers, and contactors.
Electric Vehicle Charging Stations Internal power distribution harnesses in EV chargers route AC input from the main cable to control boards via pluggable terminals and to safety relays and contactors via spade connections, following IEC wiring color standards for compliance.
Industrial Machinery & Motor Control Used in motor control centers, frequency drives, and conveyor systems where power distribution from a main cable to multiple contactors, overload relays, and PCB interface boards requires a single organized harness rather than point-to-point field wiring.
Lighting Control & Power Distribution Connects main power feeds to driver PCBs via pluggable terminal blocks and to switching devices via spade connectors in commercial LED lighting control cabinets and theatrical/architectural dimming systems.
