OJL distribution blocks are intended for distributing conductors with larger cross-section to several smaller ones. These blocks are provided in six standard designs with a nominal connecting cross-section of 70 mm² (six outputs), 120 mm² (eleven outputs) and 240 mm² (seven outputs). Execution AF and AFS are designed for connecting (input) of busbars 10 x 25 mm or several bars of 1 x 25 mm. OJL blocks are intended for all types of Al and Cu conductors. The screws are tightened by a hexagonal key. Blocks can be installed on a standard DIN rail or can be mounted using screws on a flat solid surface. Colour design is gray (RAL 7035). Maximum operating temperature is 80 °C. Housing for all design types has a protection class IP 20. OJL distribution blocks have dark transparent plastic cover top, which is not necessary to open for assembling and disassembling output (smaller) conductors. Cover sealing is possible in models AS and AFS. Products are tested according to EN 61238-1: 2003 and EN 60947-7-1: 2009.
