Overview
The Square D 8501-AP-50 machine tool relay Series B is a plug-in general-purpose relay from Square D’s established 8501-class product line. The 8501-AP-50 is engineered for switching and control applications in industrial machine tool environments and automation systems. This relay type combines compact design with industry-standard contact configurations, making it suitable for retrofit and replacement applications in legacy control panels.
Key Features
- Plug-in relay format compatible with standard 8501-series sockets
- Series B construction for proven reliability in machine tool applications
- General-purpose switching suitable for AC and pilot-duty applications
- Industry-standard terminal arrangement for straightforward panel integration
- Compact form factor for space-constrained control cabinets
Technical Specifications
Verify specific coil voltage, contact configuration, and current ratings with your system documentation or supplier, as this is a legacy product. The 8501 series family typically operates at standard industrial voltages (AC: 120/240V; DC: up to 28V nominal) with contact ratings suitable for general-purpose and light motor control applications.
Typical Applications
- Machine tool control circuits and logic sequencing
- Pilot-duty switching in industrial automation systems
- General-purpose relay replacement in legacy equipment
- Control signal distribution in switchgear and control panels
- Standby or backup control circuits
Compatibility & Replacements
Compatible With
- Square D 8501-series relay sockets (verify socket type with product documentation)
