The RR3B-UAC24V is a 3-pole general-purpose power relay manufactured by IDEC, featuring a 24V AC coil with blade-style (BA) termination for reliable switching in industrial control systems. The relay operates at 105 mA (60 Hz) or 121 mA (50 Hz) with a coil resistance of 79 O and delivers contact ratings of 10 A at 120V AC (resistive) and 7.5 A at 120V AC (inductive). It provides fast switching with an operating time of 25 ms maximum and release time of 25 ms maximum, with a frequency response of 1,800 operations per hour and electrical life expectancy exceeding 500,000 operations. The relay features silver contacts with 30 mO maximum contact resistance, 2,000V AC dielectric strength between circuits, and operates reliably across -30°C to +70°C. Common applications include motor control, power distribution, and industrial automation where compact blade-style relays with high reliability and long service life are required.
