ABB 1SBN010110R1001 CA4-01 auxiliary contacts

• Contact Configuration: 4 normally open (NO) contacts (single-pole, double-throw optional via wiring)​

• Rated Voltage: 230 V AC / 24 V DC (compatible with standard control system signals)​

• Rated Current: 6 A (continuous at 230 V AC; 3 A at 24 V DC)​

• Breaking Capacity: 6 A (resistive load) / 0.6 A (inductive load, cosφ=0.4)​

• Contact Material: Silver-nickel (AgNi) alloy (high conductivity, anti-arc erosion)​

• Insulation Voltage: 690 V AC (between contacts and housing)​

• Dielectric Strength: 2.5 kV AC (1 minute, between contacts and ground)​

• Mechanical Life: ≥10 million operations (ensures long service in high-cycle applications)​

• Electrical Life: ≥100,000 operations (at rated current/voltage)​

• Operating Temperature: -25°C ~ +70°C (adapts to industrial control cabinet environments)​

• Storage Temperature: -40°C ~ +85°C​

• Protection Degree: IP20 (against finger touch and large dust particles; for cabinet-mounted use)​

• Mounting: Direct clip-on installation to ABB circuit breakers (e.g., Tmax series) / contactors (e.g., AF series); no additional tools required​

• Low-Voltage Distribution: Status monitoring of main circuit breakers in factory power distribution panels (transmits "breaker closed/open" signals to PLCs)​

• Motor Control: Interlocking for motor contactors (e.g., prevents simultaneous activation of forward/reverse contactors via NO contacts)​

• Process Control: Fault signal transmission for pump/compressor circuit breakers in chemical plants (triggers alarm systems via auxiliary contacts)​

• Building Automation: Status feedback of lighting/HVAC circuit breakers to building management systems (BMS)​

• Align the module’s clip with the mounting rail of ABB main devices (circuit breaker/contactor) and push until a "click" is heard (ensures secure engagement)​

• Wire NO contacts to control system inputs; use 0.5-1.5 mm² copper cables; tighten terminal screws to 0.5-0.8 N·m torque​

• Verify contact continuity with a multimeter before system startup (ensure no open circuits due to poor wiring)​

• Check contact status quarterly (measure resistance via multimeter; normal resistance <50 mΩ)​

• Clean contact terminals with a dry brush (remove dust to avoid poor contact); avoid using abrasive materials (prevents contact damage)​

• Replace the module if contacts stick or show signs of overheating (discoloration of terminals indicates arc erosion)​
