IDEC Relays SR3B-05 Mount Socket

The IDEC SR3B-05 Relay Socket is a professional-grade 11-pin DIN rail mount socket engineered specifically for IDEC RR Series power relays. Designed to handle single, double, and triple pole (3PDT) configurations, this high-capacity socket is a standard for contractors managing industrial automation and HVAC control panels. As a direct replacement for 3TX7144-1E4, the SR3B-05 utilizes heavy-duty M3.5 screw terminals to ensure high-torque wire retention and electrical stability in high-vibration environments. The blade terminal design simplifies relay seating and replacement, significantly reducing downtime during maintenance cycles. With a 300V voltage rating and 10A current capacity, this IDEC 11-pin socket provides the thermal management and dielectric strength required for demanding motor control and logic circuit applications. Whether you are retrofitting existing cabinets or building new panels, this DIN rail relay base delivers the reliability expected by veteran field technicians.

• Universal Compatibility: Seamlessly integrates with RR2P and RR3P Series relays for versatile field applications.
• Industrial Build Quality: Features finger-safe screw terminals and robust housing to prevent accidental contact and short circuits.
• Efficient Installation: Optimized for 35mm DIN rail mounting with a secure snap-on mechanism for rapid panel assembly.
• High-Amperage Rating: Supports 10-amp power circuits, making it suitable for heavy-duty HVAC mechanical loads.
• Direct Cross-Reference: Eliminates guesswork when replacing legacy Siemens 3TX7144-1E4 sockets in older control systems.

Is the SR3B-05 compatible with 8-pin relays?
No, the SR3B-05 is an 11-pin relay socket designed for 3-pole relays. For 8-pin (2-pole) RR series relays, use the SR2P-05 socket.

What is the maximum wire size for the screw terminals?
The M3.5 screw terminals are designed to accommodate up to 2 x 2.0mm² (14 AWG) wires, providing secure contact for standard industrial control wiring.

Can this socket be surface mounted?
While optimized for 35mm DIN rail, the base includes mounting holes that allow for direct surface mounting using M4 or #8 screws if a rail is not available.
