Siemens 3TH42 62-0BB4 Control Relay

Siemens 3TH4262-0BB4 Contactor Relay is a 3-pole control relay with a 24 V DC coil designed for industrial control circuits. It provides a 6 normally open and 2 normally closed auxiliary contact block alongside its three main contacts, enabling multiple signaling paths and interlocking in a compact package. The auxiliary contacts and control coil are wired through screw terminals, and the unit carries an IP20 front rating for indoor panel installations. In AC-15 service, the main contacts are rated for up to 10 A at 230 V AC and 6 A at 400 V AC. This device is part of Siemens’ 3TH42 family in the 62E series and supports straightforward integration into standard control cabinets where reliable, isolated switching and signaling are required from a single relay module. Common applications include control circuits for motors, conveyors, and other automation panels that require multiple auxiliary signals from a compact relay.
