This industrial-grade electromagnetic power relay series offers versatile switching solutions for demanding control applications. Available in three models - HH52P (8-pin), HH53P (11-pin), and HH54P (14-pin) - each featuring different contact configurations to suit various circuit requirements. The HH52P provides 2NO+2NC contacts, HH53P offers 3NO+3NC, and HH54P delivers 4NO+4NC arrangements. Built with premium silver alloy contacts, these relays ensure reliable switching performance with contact ratings up to 5A at 250VAC for HH52P/HH53P models and 3A at 250VAC for the HH54P model. The housing is constructed from flame-retardant frosted PC material, providing robust protection in industrial environments. A convenient transparent window with LED status indicators (red for AC, green for DC) enables quick operational monitoring. The modular plug-in design with detachable base facilitates easy installation and maintenance. The pure copper coil construction ensures consistent performance, while the comprehensive pin configurations allow for flexible integration into various control systems. These relays are ideal for industrial automation, power distribution, and equipment control applications where reliability and durability are essential.
