The RH3B-LD-DC24V is a 3-pole (3PDT) compact power relay designed for DC switching applications with a 24 VDC coil. This relay features an integrated LED indicator and surge absorber diode, providing visual feedback and protection against voltage spikes in the control circuit. The relay maintains the same compact height as the basic type while incorporating these additional protective and signaling components. With a 10 A contact capacity per pole, it is suitable for industrial control systems, automation equipment, and machinery requiring reliable switching of moderate-current loads. The combination of indicator LED, diode protection, and compact form factor makes it ideal for panel-mounted applications where space is limited and circuit protection is essential.
