Siemens Industrial Controls 3TX7114-5LF13 Relay

The Siemens SIRIUS 3TX7114-5LF13 is a high-performance 120V DPDT 15A Miniature Relay engineered for heavy-duty industrial control and HVACR logic circuits. This 8-pin square base plug-in relay is a staple for technicians requiring reliable switching in compact enclosures. Featuring a DPDT contact configuration, it provides the versatility to control two separate circuits simultaneously, making it ideal for interlocking and motor control applications. The integrated LED indicator and mechanical flag offer immediate visual diagnostics, significantly reducing troubleshooting time during field service calls. Designed for peak performance, this Siemens industrial control relay handles inductive loads up to 1/2 HP at 120V and 1 HP at 240V, ensuring compatibility with standard blower motors and heavy-duty actuators.

• Enhanced Visual Diagnostics: Includes both a high-visibility LED status lamp and a mechanical flag indicator for rapid circuit verification.
• Commissioning Convenience: Equipped with a push-to-test button and a latching hold-down door to manually activate contacts without applying coil power.
• Robust Switching Capacity: Rated for a 15A contact current, providing a high margin of safety for demanding HVACR systems.
• Reliable Socket Compatibility: Engineered for use with Siemens 3TX7144-1E6 or 3TX7144-4E6 sockets for secure, vibration-resistant DIN-rail mounting.
• Compact Footprint: The miniature premium design fits into tight control panels without sacrificing thermal stability or electrical clearance.

What is the maximum voltage rating for the contacts on the 3TX7114-5LF13?
While the coil operates at 120VAC, the silver alloy contacts are rated for up to 300VAC, allowing for use in higher voltage load switching applications.

Can this relay be used for manual circuit testing?
Yes, the latching hold-down door allows technicians to mechanically override the relay to test downstream components without energizing the coil.

Is this relay suitable for low-temperature environments?
The 3TX7114-5LF13 is rated for operation in temperatures ranging from -40°C to +55°C, making it suitable for unconditioned mechanical rooms and refrigeration controls.
