Product Description
120A Square Terminal Block for DC Power Distribution
The SL-120A-A 120A Square Terminal Block is a panel-mounted electrical connection component designed for battery storage systems, inverter assemblies, and DC power distribution equipment. Its single-threaded structure provides a connection point for power conductors in electrical installations where a compact, insulated terminal is required.
With a rated current of 120A and a rated voltage of 600V DC, the SL-120A-A is intended for applications involving DC power connections. The terminal block combines an H62 brass conductive component with an insulated square housing for integration into electrical panels and equipment enclosures.
Available in red and black, the terminal block provides different housing color options for equipment manufacturers, electrical panel builders, and system integrators.
Key Features of the SL-120A-A Terminal Block
1. Single-Threaded Connection Structure
The SL-120A-A features a single-threaded connection design that allows electrical conductors or compatible cable terminals to be secured using appropriate fastening hardware.
Compared with double-threaded configurations, this structure offers a different terminal arrangement for equipment requiring a single threaded connection point.
2. 120A Current Rating
Designed with a 120A rated current, this square terminal block provides a connection option for compatible DC electrical equipment.
The terminal should be selected according to the system current, conductor specifications, installation conditions, and applicable electrical requirements.
3. H62 Brass Conductive Component
The conductive component uses H62 brass, providing electrical conductivity and mechanical strength for terminal connections.
Proper fastening and suitable conductor termination are important for maintaining reliable electrical contact during equipment operation.
4. Insulated Square Housing
The terminal block features an insulating housing manufactured from PA66 material, as indicated in the supplied general product specifications.
The housing helps separate the conductive connection from surrounding equipment components and provides mechanical support for the terminal assembly.
5. Panel-Mounting Configuration
The SL-120A-A is designed for mounting onto electrical equipment panels or enclosure surfaces.
Its square structure supports organized terminal positioning in power distribution assemblies. The mounting opening, fastening hardware, and installation clearances should be determined using the corresponding dimensional drawing.
