MS132-T circuit breakers for transformer protection
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.
