The RR3B-ULCAC120V is a 3-pole double-throw (3PDT) general-purpose power relay manufactured by IDEC with a 120V AC coil and blade-style termination. The relay features a rated coil current of 20.5 mA at 60 Hz with a coil resistance of 2100 O and operates with a maximum operating time of 25 ms and release time of 25 ms. It is rated for 10 A at 120V AC resistive load and 7.5 A at 120V AC inductive load, with a contact material of silver and maximum contact resistance of 30 mO. The relay operates across a temperature range of -30 to +70 °C, withstands dielectric strength of 2000V AC for 1 minute between live and dead parts, and has an insulation resistance of 100 MO minimum. With over 500,000 electrical operations at 120V and 50/60 Hz at 10A, this relay is ideal for industrial control, motor switching, and power distribution applications requiring reliable long-term performance.
