Description
Phoenix Contact 2961435 REL-MR-24AC/21-21 Relay
The Phoenix Contact 2961435 REL-MR-24AC/21-21 is a miniature electromechanical power relay designed for electrical control and switching applications. It uses a 24 V AC coil to operate two changeover contacts, allowing a control signal to switch connected circuits.
Its compact housing and plug-in/solder connection design make it suitable for compatible electronic equipment and relay assemblies. The relay is intended for use with the appropriate mounting accessories and must be selected according to the connected load and control-circuit requirements.
Key Features
– **24 V AC coil:** Operates from a compatible 24 V AC control supply.
– **Two changeover contacts:** Provides two changeover poles for switching circuits.
– **8 A continuous-current rating:** Applies under the manufacturer’s specified operating conditions.
– **250 V AC/DC maximum switching voltage:** The permissible load depends on the switching conditions and load type.
– **Silver-nickel contacts:** Uses AgNi contact material.
– **Compact construction:** Designed for integration into compatible electronic assemblies.
– **Wash-proof construction:** Classified RT III by the manufacturer.
– **Industrial approvals:** Manufacturer documentation lists relevant UL, cULus and VDE approvals.

The relay’s 8 A continuous-current rating should not be treated as a universal rating for every load. Switching capacity varies with voltage, load type and operating conditions. Refer to the manufacturer’s technical data before using it for inductive or motor loads.
Typical Applications
Depending on the circuit design and electrical ratings, the Phoenix Contact 2961435 relay may be used in:
– Industrial automation and control panels
– Electrical switching circuits
– Building and equipment control
– Interface and signal switching applications
– Compatible heating and appliance controls
– General-purpose control systems
Installation and Compatibility
Before installation, confirm that the control circuit supplies 24 V AC rather than 24 V DC. Check the terminal layout, contact arrangement and required mounting accessories. The manufacturer lists compatible relay bases, including the 2900931 and 2900930 models.
Ensure that load current, switching voltage and inrush current remain within the appropriate limits. Installation should follow the official wiring instructions and be completed by a qualified technician.
