Miniature Circuit Breakers RI50

Features

• Due the low permissible L2T (let through) values can be used smaller size of metal boxes
• Low let-through energy under short-circuit conditions ensures longer life of contacts and reduces thermal stresses in the distribution circuit
• RI50 reduces the energy loss due to a unique contact configuration and reduction of hot spots. Watt loss per pole for RI50 is far lower than that specified in IEC/EN 60898
• An optional operating position
• IP20 degree of protection; IP40 degree of protection after installation in a distribution box
• An additional color indication of the position of main contacts (red: contacts closed — green: contacts open)
