SIEMENS 3RT2337-1AP00 SIRIUS 4-pole Contactor, AC-1 110A, 230VAC Coil

Overview The SIEMENS 3RT2337-1AP00 is a SIRIUS 3RT23 series four-pole contactor, size S2, designed for resistive load switching under AC-1 utilization category. It is widely stocked as spare for distribution panels, heating circuits and non-motor load switching in industrial low-voltage systems.

Features This 4-pole contactor comes with screw terminals, integrated 1NO+1NC auxiliary contacts. The 3RT2337-1AP00 has 230V AC 50Hz coil voltage, high mechanical endurance and optional add-on accessories including auxiliary blocks, surge suppressors and mechanical interlocks. It is compliant with IEC 60947-4-1.

Specs Model: 3RT2337-1AP00 Series: Siemens SIRIUS 3RT23 Type: 4-pole power contactor Utilization category: AC-1 Rated current: 110A @400V Coil voltage: 230VAC 50Hz Auxiliary contacts: 1NO + 1NC Frame size: S2 Mounting: 35mm DIN rail Protection class: IP20 Certifications: CE, UL, IEC Product status: active industrial electrical spare

Principle When the coil is energized, electromagnetic force pulls the armature closed to switch the four main power contacts. The auxiliary contacts provide status feedback for PLC indication and interlock logic. The contactor breaks the circuit once coil power is removed.

Applications The 3RT2337-1AP00 is widely deployed in factory distribution cabinets, HVAC heating systems, lighting banks and water treatment control panels. It is used for switching resistive loads and general AC distribution circuits.
