6.Outline and Mounting dimensions
Circuit breaker terminals and polarity mark shown in picture 3
1)Be sure to pay attention when wiring in the circuit breaker terminals of the polarity signs,to ensure that the current direction of the internal circuit breaker for the "+" into the most,"-" very outflow(see picture 3)
2)Circuit breaker can be installed vertically,but also the level of installation,does not affect the use of performance
3)Circuit breaker before the current value of the factory setting pass,the user can not adjust
4)Auxiliary circuit breaker contact,and contact the police sub-Lai release,and so on in the annex to General "DZX2/4 Series circuit breaker annex"
User need attention the entitle type,character and volume of breaker and accessories
For example:GSB1Z-40 20A/1P breaker 200sets
