f) This series of circuit breakers are rail-mounted, and TH35-7.5 steel mounting rails are available.
g) When the ambient temperature changes, the rated current value is corrected accordingly, and the
temperature correction coefficients are listed in Table 4;

h) When the handle moves upwards, this means that the circuit is in the ON state; when the handle moves
downwards, this means that the circuit is in the OFF state;
i) Insert the residual current operated circuit breaker into the mounting rail until it is fixed on the rail without
any looseness or falling off. To remove the residual current operated circuit breaker, push it upward
forcedly and pull its upper portion outwards until the circuit beaker is removed from the mounting rail.
Maintenance and repair:
a) The maintenance and repair of the product must be performed by qualified professionals;
b) Do not maintain or repair the live product;
c) Maintain the product once a year under normal operating conditions.The maintenance contents see Table
