Siemens 3RH21221AV60 Contactor Relay

Product Description

The SIEMENS 3RH21221AV60 is a contactor relay designed for use in industrial control panel applications. Contactor relay devices of this type serve as auxiliary switching elements, expanding the contact capacity of control circuits without directly switching high-power loads. The 3RH21221AV60 fits into the SIEMENS SIRIUS control device family and is installed by licensed electricians or qualified industrial maintenance technicians working on motor control centers, control panels, or automated machinery. Its compact form factor measures 2.421 inches long by 1.969 inches wide by 3.051 inches high, and the unit ships at 0.520 pounds.

This contactor relay is suited for use in both commercial and industrial electrical control systems. Typical applications include motor starter auxiliary circuits, interlocking control logic, signaling circuits, and other low-voltage switching tasks inside control enclosures. It is commonly found in manufacturing facilities, HVAC mechanical rooms, pump control panels, and process automation equipment where reliable auxiliary contact switching is required.
