Siemens 3RT2636-1NB33 Capacitor Contactor, 50kVAR, AC/DC 20-33V, Size S2 Original Brand New

Overview

The Siemens 3RT2636-1NB33 is a high-performance capacitor contactor from the SIRIUS series, specifically designed for switching capacitive loads (AC-6b) up to 50 kVAR at 400 V. This specialized contactor is engineered to minimize the negative impact of switching capacitive loads on the power supply network. It achieves this by utilizing leading auxiliary contacts that engage precharging resistors before the main contacts close. This critical function effectively limits the peak charging current, ensuring network stability and protecting connected equipment.

Ideal for use in reactive current compensation systems, the 3RT2636-1NB33 can switch both choked and unchoked capacitors. It is also suitable for switching converters. This robust and reliable contactor features an integrated varistor for surge suppression, a 3-pole design, and a wide control voltage range of 20-33 V AC/DC.

The unit comes with 1 NO + 1 NC auxiliary contacts and a convenient screw terminal for secure connections. The compact Size S2 form factor makes it an excellent choice for various industrial and commercial applications where space is a consideration.
