Product description

The Siemens 3TH2022-7AP0 is a contactor relay from the 22E series, built to EN 50011 standards. It features 2 normally open (NO) and 2 normally closed (NC) contacts, and operates with an AC coil voltage of 230 V AC at 50 Hz or 277 V AC at 60 Hz. This relay is equipped with flat connector terminals for simplified wiring.

This relay is utilized in control circuits for various industrial automation tasks. The combination of NO and NC contacts, along with the fast connection capability of flat terminals, makes it suitable for applications requiring efficient assembly and reliable control within machinery and control panels.

Stanlo Automation, a veteran-owned surplus parts distributor, offers the Siemens 3TH2022-7AP0. This product is phased out, and its replacement is the SIRIUS 3RH21 series. We provide this component to ensure the continued operation of your existing equipment.
