off switch 40A 2-pole On/off switches for mounting on standard rails for controlling electrical systems. The 5TL1 On/Off switches are used for the switching of lighting, motors and other electrical devices. Rated currents range from 32 A to 125 A. The 5TL1 device versions can also be used as switch disconnectors according to EN 60947-1 and serve as main control switches for the disconnection or isolation of plants according to EN 60204-1. Whether for infrastructure or for industrial requirements, Siemens provides switchgears for all applications and every application area. The new design of the 5TL1 On/Off switches means they are optically perfectly integrated into the RCCB and MCB series. Key features of the switchgears from Siemens: 1. Increased operational safety and system availability due to separate connection and disconnection of the affected circuit. 2. Reliable safety during installation with standard reach-around and touch protection. 3. Toolless removal from the DIN rail or from the bus bar assembly by means of conveniently actuating a manual slide. 4. Clearly visible switch position indicator. 5. Can be used as switch disconnector and main switch. 6. The on/off switches comply with the provisions of EN 60947-1 and EN 60204-1. 7. Optimized technology for your safety – only from Siemens.
