Introduction to the installation and connection of Siemens circuit breaker 3WT

Siemens circuit breaker 3WT installation method

Warning: Before installing the equipment, make sure that the minimum spacing requirements between insulating, grounding and conductive components are met in the switch cabinet.

1. Installation location

Warning: The Siemens circuit breaker is installed obliquely. When it is moved into the off position, the circuit breaker may slide out of the guide rail.
