Product description

The Siemens 3TH2022-0AP0 is a contactor relay belonging to the 22E series, conforming to EN 50011 standards. It is equipped with 2 normally open (NO) and 2 normally closed (NC) contacts. This relay operates on AC with a coil voltage of 230 V AC at 50 Hz or 277 V AC at 60 Hz, featuring standard screw terminals for connection.

This relay is designed for auxiliary control functions within industrial automation systems. Its 2 NO and 2 NC contact arrangement makes it versatile for interlocking, signaling, and sequence control in various applications, such as motor control circuits and process automation.

As a veteran-owned surplus parts distributor, Stanlo Automation provides the Siemens 3TH2022-0AP0. This product is phased out, and its successor is the SIRIUS 3RH21 series. We offer this component for maintaining existing installations, providing a cost-effective solution.
