Siemens 3RT2016-1VB42 Power Contactor 9A, 4kW, 24V DC, 1NC, S00 Original Brand New

Overview: Siemens 3RT2016-1VB42 SIRIUS Power Contactor

The Siemens 3RT2016-1VB42 is a high-performance, compact power contactor from the trusted SIRIUS 3RT2 series, specifically engineered for switching motors and general resistive loads up to (AC-3e/AC-3). Its small, size S00 form factor makes it ideal for space-saving control panel designs. This model is a 3-pole device featuring robust screw terminals for secure and straightforward wiring in industrial applications.

It is particularly well-suited for direct control from PLCs or low-power control systems due to its highly efficient, operating mechanism. The coil includes an integrated diode for effective surge suppression, protecting sensitive control electronics without the need for external components.
