Siemens 3RH22711BB40 Control Relay

Product Description

The SIEMENS 3RH22711BB40 is a control relay designed for use in industrial and commercial electrical control circuits. It functions as a switching device that opens or closes circuits in response to control signals, enabling sequencing, interlocking, and load management in automated systems. This relay is installed by licensed electricians and industrial control technicians working on motor control centers, panel boards, and machine control panels. At 0.705 pounds and with a compact footprint, it fits into tight control enclosures without sacrificing reliability.

This control relay is suited for industrial automation and building control applications where reliable switching of control circuits is required. Typical installations include motor control panels, HVAC equipment controllers, conveyor systems, and process automation panels in both commercial and light industrial environments. Electricians and controls technicians integrate this relay into ladder-logic-driven systems where hardwired interlock or auxiliary contact functions are needed.

Key Features

• Compact control relay for industrial and commercial control panel integration
• Lightweight construction at 0.705 pounds for easy panel installation
• Low-profile dimensions of 2.421 inches x 1.969 inches x 4.744 inches for space-constrained enclosures
• Designed for switching and interlocking functions in automated control circuits
• Single unit per pack for direct replacement or new installation use

Compatibility

Designed as an OEM-style replacement or direct-fit control relay for industrial motor control and automation panel applications. Consult the equipment wiring diagram and control panel documentation to verify contact configuration and coil voltage requirements before installation.

Installation Notes

Installation should be performed by a qualified electrician or controls technician in accordance with applicable NEC guidelines and local codes. De-energize the control panel and verify zero voltage with a meter before handling any relay or control device. Ensure the coil voltage and contact ratings match the existing circuit requirements before installing. Do not exceed the rated contact load for the relay.
