Product Description
The Allen-Bradley 700DC-MB310 is an IEC miniature DC control relay from the Bulletin 700-MB series, designed for reliable switching in industrial control applications. It features bifurcated "H-style" Silver Nickel (AgNi) contacts that increase switching reliability at lower power levels, and is rated for 300VAC at 10A with a contact configuration of 3 Normally Open (N.O.) and 1 Normally Closed (N.C.). This relay uses a DC coil (coil voltage specified by suffix — e.g., Z24=24VDC, Z12=12VDC, Z48=48VDC) and includes positively guided contacts across all 4 main poles per IEC 60947-5-1 Annex L, meeting IEC/EN 60947-5-1 and VDE 0660 standards. Suitable for industrial automation, machine safety circuits, PLC output control, and motor starter auxiliary control.
