New Original Siemens 3RU6116-1CB1 SIRIUS Thermal Overload Relay Full English Introduction<\/h1>\n<\/div>\n
\n

1. Product Overview<\/h2>\n<\/div>\n
\n
The 3RU6116-1CB1 is a brand-new original thermal overload relay from Siemens SIRIUS 3RU6 series, designed for overload and phase failure protection of three-phase asynchronous motors. It adopts bimetallic strip thermal induction principle and is specially matched with SIRIUS 3RT series power contactors via direct plug-in assembly without extra wiring terminals. This model features adjustable current setting range from 1.8 A to 2.5 A, with a built-in 1 normally open and 1 normally closed changeover contact for fault signal output and circuit interlock.<\/div>\n<\/div>\n
\n
The relay provides dual protection against motor long-term overload and three-phase phase loss faults, widely used in small pump motors, fan motors, conveyor drive motors, textile machine drives and packaging automation equipment. It meets IEC 60947-4-1, VDE 0660 standards, carries CE and RoHS certifications, and supports long-term stable operation in normal industrial workshop environments. The integrated compact structure simplifies cabinet wiring and reduces assembly time for complete machine manufacturers.<\/div>\n<\/div>\n
\n

2. Main Core Functions<\/h2>\n<\/div>\n
\n
    \n
  1. Thermal overload protection via bimetallic thermal deformation, automatically cutting control circuit when motor overloaded for a long time<\/li>\n
  2. Phase failure detection function, quickly trips to protect motor once any phase power supply is lost<\/li>\n
  3. Continuous adjustable rated current dial, flexible matching with different small-power motor rated currents<\/li>\n
  4. Dual reset modes: manual reset as default, switchable to automatic reset via internal sliding switch<\/li>\n
  5. 1 SPDT auxiliary contact (1NO + 1NC) for fault alarm signal transmission and contactor interlock control<\/li>\n
  6. Built-in test button for on-site manual function inspection without actual motor load operation<\/li>\n
  7. Trip stop indicator window to visually display overload tripping state for fast maintenance judgment<\/li>\n
  8. Direct plug-in mounting compatible with corresponding 3RT series contactors, eliminating separate DIN rail installation<\/li>\n
  9. Temperature compensation design to avoid false tripping caused by ambient cabinet temperature change<\/li>\n
  10. Finger-safe IP20 housing to prevent accidental electric shock during cabinet maintenance<\/li>\n<\/ol>\n<\/div>\n
    \n
