Siemens Disconnect Switch 63A 3-pole On/Off switch for mounting on DIN rails for controlling electrical systems. The 5TL1 On/Off switches are used for switching lighting, motors, and other electrical devices. The rated currents range from 32 A to 125 A. The 5TL1 device variants can also be used as load disconnect switches according to EN 60947-1. The devices may be used as main switches for disconnecting or isolating systems according to EN 60204-1. Whether for infrastructure or industrial requirements, Siemens offers switching devices for all applications and every area of use. The new design allows the 5TL1 On/Off switch to be visually integrated perfectly into the series of RCDs and circuit breakers. Siemens switching devices are characterized primarily by: 1. Increased operational safety and system availability thanks to separate on/off control of the affected circuit. 2. Reliable safety during installation due to standard included protection against accidental contact and touching. 3. Tool-free removal from the DIN rail or busbar assembly through convenient slider manual operation. 4. Clearly visible switching position indicator. 5. Usable as a load disconnect switch and main switch. 6. The On/Off switches comply with the requirements of EN 60947-1 and EN 60204-1. 7. Optimal technology for your safety – only from Siemens. Siemens offers a comprehensive portfolio of protection, switching, measuring, and monitoring devices, as well as distribution systems for safe and efficient electrical infrastructure in buildings and industry.
