The **ME26XBX-R** is an industrial-grade, panel-mount electromechanical relay manufactured by **Magnecraft** (now a brand under **Schneider Electric**). It is designed for high-reliability switching in control systems and automation. --- ### ## Technical Specifications The ME26XBX-R belongs to the **725 series** of power relays. Below are its primary technical characteristics: | Feature | Specification | | :--- | :--- | | **Contact Configuration** | DPDT (2 Form C) | | **Contact Rating** | 25 Amperes @ 277 VAC / 28 VDC | | **Coil Voltage** | 120 VAC (Standard for 'R' suffix) | | **Mounting Type** | Flange Mount (Panel Mount) | | **Terminals** | Quick Connect / Solder Terminals | | **Material** | Silver Alloy Contacts | --- ### ### Key Components and Features 1. **DPDT Contact Arrangement:** Double-Pole Double-Throw means the relay can control two separate circuits simultaneously. Each pole has a "normally open" and "normally closed" contact set. 2. **Heavy Duty Power Handling:** Unlike signal relays, the ME26XBX-R is rated for **25A**, making it suitable for starting small motors, controlling heating elements, or switching heavy lighting loads. 3. **Encapsulated Construction:** The "ME" prefix often refers to a series that includes a clear plastic dust cover, allowing visual inspection of the contacts without exposing them to environmental contaminants. 4. **Flange Mounting:** The "XBX-R" designation usually implies the physical housing has integrated mounting ears (flanges), allowing it to be screwed directly to a sub-panel rather than requiring a DIN rail socket. --- ### ### Typical Applications * **HVAC Systems:** Controlling compressors or blower motors. * **Industrial Automation:** Interfacing between PLC outputs and high-power actuators. * **Power Supplies:** Main power switching for industrial equipment. * **Lighting Control:** Managing large banks of incandescent or fluorescent ballasts. --- ### ### Wiring Example (Conceptual) ```python # Conceptual logic for a control circuit using ME26XBX-R Input_Signal = 120VAC_Control_Switch if Input_Signal == "CLOSED": Relay_Coil = "Energized" DPDT_Contact_1 = "Switches from NC to NO" # Powers Load A DPDT_Contact_2 = "Switches from NC to NO" # Powers Load B else: Relay_Coil = "De-energized" DPDT_Contacts = "Return to default NC position" ```
