Product details

product description 

1SAM340000R1011 is  transformer protection

The circuit breaker for transformer protection MS132-16T is a compact 45 mm width device 

designed to protect control transformers on the primary side. This device has a rated 

operational current of Ie = 16 A. It allows fuse-less protection against overload and 

short-circuit. The short-circuit current setting is fixed to 20 times the rated operational 

current to handle the high inrush current generated by transformers. The device allows 

manually connect and disconnect the transformer from the mains thanks of its built-in 

disconnection function. The circuit breaker for transformer protection offers a rated service 

short-circuit breaking capacity of Ics = 100 kA at 400 VAC and a trip class 10. Further features 

are temperature compensation, trip-free mechanism, rotary handle with a clear switch position 

indication and short circuit trip indicator. The handle is lockable to protect against unauthorized 

changes. Auxiliary contacts, signalling contacts, undervoltage releases, shunt trips, power in-feed 

blocks and terminal spacers are available as accessory.
