Overview
The Allen-Bradley 700-HC24A1 is a miniature ice cube relay engineered for general-purpose switching applications in industrial control circuits. This 4PDT (4-pole, double-throw) relay operates on 120V AC 50/60Hz control voltage and delivers reliable performance in relay logic, motor control, and automation systems. The compact ice cube form factor fits standard relay sockets for easy installation and replacement in existing control panels.
Key Features
- 4-pole, double-throw (4PDT) contact arrangement providing four independent changeover contact sets
- 7-amp contact rating with silver contacts for dependable electrical continuity
- 120V 50/60Hz coil voltage for standard industrial AC supply
- Low-energy coil design (10V, 10mA minimum pickup)
- On/off flag indicator for visual status confirmation
- Clear polycarbonate cover permits visual inspection of contacts and flag mechanism
- Electrical schematic printed on faceplate for quick reference during installation and troubleshooting
