Description
The Siemens 3RT2016-1KB41 is a compact and reliable coupling contactor designed for motor and load switching applications in industrial automation systems. Rated at 9 A under AC-3 duty, it supports motors up to 4 kW at 400 V, ensuring dependable performance in standard motor control tasks.
Equipped with a 24 V DC coil (0.7–1.25 × Uc) and an integrated suppressor diode, this contactor is especially suitable for direct PLC output control, protecting electronic outputs from voltage spikes during coil switching.
This 3-pole contactor (frame size S00) includes 1 normally open (NO) auxiliary contact for signaling or interlocking functions. The screw terminal connections provide secure and stable wiring. Due to its compact design, it is ideal for installations where space is limited; note that no additional auxiliary switch can be added.
The 3RT2016-1KB41 offers efficient switching performance and electrical protection in control panels, motor starters, and automation systems.
