MS132-T Circuit breakers for transformer protection are electro
mechanical protection devices specially designed to protect control
transformers on the primary side.
The short-circuit current setting is fixed to 20 times the operating
current to handle the high inrush current generated by transformers.
With this solution of door coupling rotary mechanism it is possible
to operate a Manual Motor Starter in the back of a switch cabinet
from outside.
The door coupling mechanism prevents opening of the door of a switch
cabinet with the Manual Motor Starter in ON position. The complete
mechanism includes handle, shaft, driver, shaft alignment ring and
shaft supporter.
All accessories fit for 6 mm shafts with a maximum length of 180 mm.
The degree of protection for handles MSHD is IP64.
The short-circuit current setting is fixed to 20 times the operating
current to handle the high inrush current generated by transformers.
