Description
Product Introduction
1SSS444609R1100 is snap-on auxiliary contact module for ABB contactor series. It is an accessory clipped onto contactor front or side to expand spare auxiliary contacts for interlock and running signal feedback. Original new stock and fully tested refurbished products are used for cabinet assembly and field maintenance replacement.
Model Definition
1SSS is fixed part prefix for ABB low voltage auxiliary component coding. 444609 stands for base specification code of this auxiliary contact unit. Suffix R1100 denotes factory standard hardware revision and default contact configuration. Other revised versions only modify minor internal parts without changing mounting dimension and electrical specifications.
Technical Specifications
Rated applicable voltage up to AC/DC 250V for control circuit. Adopts snap-in installation structure matching designated ABB contactor models. Operating ambient temperature ranges from -20℃ to +60℃, storage temperature -40℃~+85℃, relative humidity 5%~95% non-condensing. Protection grade IP20, compliant with IEC and CE industrial standards with long mechanical service life.
Interface and Communication Configuration
Screw terminals are provided for external control wiring connection. No built-in communication or fieldbus port, all signal transmission depends on hardwire cable connection with peripheral control devices.
Core Functions
Follow the mechanical movement of paired main contactor to achieve synchronous contact opening and closing. Provide switching signals for PLC status feedback, indicator lamp control and system safety interlock when the original built-in contact points of contactor are insufficient.
Application Scenarios
Applied in motor control cabinets for pumps, fans and compressors, low voltage control panels in chemical, metallurgy and water treatment industries for logic interlock and equipment operation feedback.
Operation and Maintenance Instructions
Cut off control power supply before installation or removal and wait for residual voltage release. Conduct semi-annual maintenance to clear dust on terminals with dry compressed air and retighten wiring screws. When abnormal switching occurs, check clip installation condition first before replacement, avoid overcurrent to prevent contact burnout.
