It switches motor loads up to 3 kW in AC-2 duty at 400 V and handles 6.5 A in AC-4 reversing or plugging service at the same voltage. The main and auxiliary circuits terminate through spring-loaded terminals, accepting 2x (0.25... 2.5 mm²) solid or stranded wire or 2x (24... 14 AWG). Side-by-side mounting is permitted, which means the 45 mm width per pole stacks cleanly in a multi-contactor group without forced spacing. The enclosure carries IP20 on the front and at the terminals, suitable for enclosed panel environments where no washdown or dust ingress protection is needed.
The integrated diode suppresses the inductive kickback on coil de-energization, which protects nearby electronics and simplifies panel wiring — no external flyback diode needed across the coil terminals. These are the ratings that govern real motor life, not the thermal current alone. Type 1 and Type 2 coordination fuse requirements are specified: 35 A gL/gG for Type 1, 20 A gL/gG for Type 2. This means the contactor withstands fault current up to those fuse let-through levels without welding or fire risk, which is critical for meeting IEC 60947-4-1 short-circuit coordination in a panel schedule.
Where this class of part is used
Power contactors of this size (S00) are the standard building block for controlling three-phase motors up to about 4 kW, resistive heating loads, and capacitor banks in industrial control panels. The 3RT1015-2JB41 fits into motor control centers, conveyor drives, pump panels, and HVAC equipment where a 24 VDC control voltage is already available from a PLC or safety relay.
For compliance documentation, the part carries a substance prohibitance date of 01.07.2006, aligning with RoHS and REACH substance restrictions. The IEC 81346-2 reference code Q confirms its function as a switching device for power circuits, which is relevant for panel documentation and traceability audits.
