Hirose Electric EF2 ZERO SCREW™ Terminal Blocks
Hirose Electric EF2 ZERO SCREW™ Terminal Blocks are spring terminal blocks designed to connect cables to electrical equipment such as power distribution in buildings without using screws. By eliminating screws, Hirose EF2 saves installation work and maintenance and also prevents accidental fires triggered by the loosening of screws in electrical power applications. These ZERO SCREW terminal blocks use a single-action positive lock connection method for inserting standard ring terminals and maintaining stable connections regardless of the operator. Hirose EF2 terminal blocks are easy to use in narrow and dimly lit places. The series offers wide cable sizes (1.25mm2 to 200mm2) and supports a wide current range (16A to 400A).
