BENEFITS
TYPES
2
Due the low permissible I t (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
RI 50 reduces the energy loss due to a unique contact configuration and reduction of hot spots. Watt loss per pole for
RI 50 is far lower than that specified inIEC/EN 60898
An optional operating position
IP20 degree of protection; IP40 degree of protection after installation in a distribution box
An additional colour indication of the position of main contacts (red: contacts closed; green: contacts open)
