3RT2036-1AH20
Siemens 3RT2036-1AH20 power contactor, SIRIUS 3RT2 series, Size S2, 3 poles, AC-3 rated 51A, 22kW (400V), control voltage 48VAC/50-60Hz, with 1NO+1NC auxiliary contacts.
Product Positioning
The Siemens 3RT2036-1AH20 power contactor belongs to the SIRIUS 3RT2 standard series. It is a Size S2, 3-pole design, with an AC-3 rated current of 51A and a power of 22kW (400V). The Siemens 3RT2036-1AH20 coil control voltage is designed for a low-voltage 48VAC design, supports 50/60Hz dual frequency, and has built-in 1NO+1NC auxiliary contacts, making it suitable for control circuits with high safety voltage requirements.
Core Product Advantages and Features
48VAC low-voltage coil
The control circuit is driven by a safe extra-low voltage to reduce the risk of electric shock.
1NO+1NC auxiliary contact
It has one set of normally open and one set of normally closed circuits built in, for use in status feedback and interlocking control.
AC-3 rated 51A, 22kW
A 22kW three-phase motor can be started directly at 400V, with the main circuit voltage separated from the coil voltage.
Size S2 screw terminal
The main circuit is fixed with screws and has a rated insulation voltage of 690V, suitable for industrial power distribution.
