描述

The RR3PA-ULDC24V is a 3-pole general-purpose power relay with a 24 VDC coil designed for industrial control and switching applications. It features a 3PDT (3-pole double-throw) contact configuration with silver contacts rated for 10 A at 30 VDC resistive load and 7.5 A at 30 VDC inductive load, with a maximum contact resistance of 30 mO. The relay operates at 60 mA coil current with 400 O coil resistance at 20°C, achieving operate and release times of 25 ms maximum, and supports a frequency response of 1,800 operations per hour. It provides 1,500 V AC dielectric strength between live and dead parts, 100 MO minimum insulation resistance, and operates reliably across -30°C to +70°C with mechanical life expectancy exceeding 10,000,000 operations. The RR3PA-ULDC24V is commonly used in industrial control panels, automation systems, and equipment requiring reliable DC switching with high cycle life and compact pin-style packaging compatible with standard DIN rail and panel-mount sockets.
