Overview
The Allen-Bradley 700-HG45Z24 is an open-type general-purpose power relay designed for industrial switching and load control applications. With a 24VDC coil and SPST-NO-DM (Single Pole Single Throw – Normally Open – Double Make) contact arrangement, this relay delivers a 40A switching capacity at 120/240VAC and is particularly suited for DC load circuits where reliable, low-cost switching is required. Panel-mounted with screw terminals, the 700-HG45Z24 provides drop-in compatibility in legacy and modern control systems.
Key Features
- 40A contact rating at 120/240VAC; 12A at 480VAC; 10A at 600VAC—handles standard industrial loads

Compatibility & Replacements
The 700-HG45Z24 is part of Allen-Bradley’s 700-HG series general-purpose relays and serves as a standard replacement for existing installations. For applications requiring arc suppression on higher-current DC circuits, the 700-HG45Z24-6 variant includes optional magnetic blowout. Always verify coil voltage, contact rating, and terminal configuration against your control schematic before installation. Consult distributor stock or Rockwell Automation for compatibility confirmation on legacy equipment.
