Mounting Cautions

In order to protect the housing and mechanical parts inside from

deformation, prevent excessive load at the time of part absorption

/ part deployment and mounting. A part absorption nozzle more

than 2 mm in diameter with a 3 N (5 N max.) mounting load is

recommended. Any shock to the product by the nozzle during the

mounting procedure may have a negative impact on the function of

the breaker.
