1SVR440621R5200 is a multifunctional time relay from ABB CT series, used for timing control logic inside low voltage control cabinets to realize delayed startup, delayed shutdown and sequential action of contactors and auxiliary equipment. Original new and fully tested refurbished products support cabinet assembly and field equipment maintenance replacement.

1SVR is fixed part prefix for ABB relay and timer component coding. 440621 stands for base hardware specification of this CT type multifunction timer. Suffix R5200 refers to factory standard version with fixed voltage and timing range configuration without customized modification.

Rated control supply voltage conforms to standard industrial specification, multiple selectable timing modes and adjustable timing range on front dial. Operating ambient temperature ranges from -20℃ to +60℃, storage temperature -40℃~+85℃, relative humidity 5%~95% non-condensing. Standard DIN35 rail mounting, protection grade IP20, compliant with CE and UL industrial certification standards, equipped with mechanical indicator for contact status.

Front screw terminal blocks for power input and control circuit wiring. No built-in fieldbus or Ethernet communication port, all control logic is realized via hardwire connection with peripheral contactors and auxiliary components.

Receive instant power trigger signal and execute preset delay logic to drive internal relay contacts for switching on-off control. Support multiple timing function selections to meet delayed switch-on, delayed switch-off and pulse timing requirements for automatic control loops.

Widely installed in pump, fan and compressor motor control cabinets of chemical, metallurgy, water treatment and building electrical systems for sequential startup protection and interlock delay control of motor loads.

Cut off control circuit power before wiring or parameter adjustment and wait residual voltage discharge. Conduct semi-annual maintenance to clean terminal dust with dry compressed air and retighten loose wiring screws. If timing action is abnormal, check supply voltage stability and external control circuit first before timer replacement.
