Panel space and mounting flexibility
The 3RT2336-1AH20: At 75 mm wide, 114 mm tall, and 130 mm deep, the S2 frame fits standard distribution board compartments without crowding adjacent devices.
Termination and auxiliary contact capacity
The coil connection uses screw-type terminals, and the contactor accepts up to two attachable auxiliary switch blocks, with a built-in 1 NO + 1 NC auxiliary contact configuration on the main contacts. Auxiliary contact ratings span 24 V to 690 V AC/DC, with a 10 A rated value at 24 V and 230 V, tapering to 0.1 A at 600 V — covering most pilot duty and PLC input circuits.
Thermal and mechanical endurance
Switching times are 10 to 18 ms for AC operation, with arcing time between 10 and 20 ms — fast enough for most motor starting and resistive load switching.
Sourcing and compliance
As an active-production part, the 3RT2336-1AH20 is sourced through authorized distribution channels and quoted to order against the BOM quantity. Compliance documentation including RoHS and REACH declarations is available from Siemens; the contactor carries CE marking for European markets.
