The RR3B-ULCDC24V is a 3-pole general-purpose power relay manufactured by IDEC with a 24 VDC coil and blade-style termination, featuring an indicator light and check button for test operation. The relay operates at a rated coil voltage of 24 VDC with a coil current of 60 mA and coil resistance of 400 O at 20 °C, with an operating time of 25 ms maximum and release time of 25 ms maximum. Contact ratings include 10 A at 30 VDC resistive load and 7.5 A at 30 VDC inductive load, with silver contact material and a maximum contact resistance of 30 mO. The relay is rated for a minimum operating voltage of 80% of rated voltage and a maximum continuous applied voltage of 110% of rated voltage, with a minimum applicable load of 24 V DC/10 mA. This relay is commonly used in industrial control systems, automation equipment, and power distribution applications where reliable switching of moderate DC loads is required.
