STG series mini circuit breaker

APPLICATIONS

To protect the electrical distribution systems and electrical devices against short-circuit(if the defect has been caused by failure or incorrect connection) and to protect the electrical distribution system against overload(if the circuit has not been damaged but an extreme thermal overload occurred which could damage the wiring).Suitable especially for common installation into switchboards and switching points of low-voltage end circuits. It is designed mostly for alternating current but they can be used also for direct current for which the reduction of short-circuit resistance by approx. about 20% has to be taken into account (because of a higher stress of contacts).
