Application

S7-63series Double power inerlock circuit breaker.The function add a interlocking based on the original HWDZ47- 63 miniature circuit.

It means that when one of the pole is opend,then another one must be closed to achieve the function of changing the power,overload protection,shot circuit protection and so on.lt’s usually used in Manostat.

Double power circuit breaker consist of the shell, operating mechanism, thermal release, electromagnetic release contact system, arc system, etc., With overload and short circuit protection. The design of a unique structure so that products with 6KA short-circuit capability, mechanical life of more than 20000 times. And has the following characteristics: an increase of interlocking function, means, when the side of the circuit breaker is turned on, the other side of the circuit breaker can only be kept off, to achieve line changing and other protection. The pole of product has many combination method like 1P+ 1P, 2P+2P, 3P+3P, 4P+4P.
