AMERICAN ZETTLER AZ2531091 50 Amp Latching Power Relay
The American Zettler AZ2531-09-1 is a robust 50 Amp latching power relay engineered for demanding applications involving heavy loads and frequent switching. Its latching functionality eliminates the need for continuous coil energization, saving power and reducing heat generation. The relay boasts a 1.5mm contact gap, a 4 kV dielectric strength, and is available with a manual switch for convenient operation. It is UL certified and suitable for use in industrial control panels, power supplies, and other applications requiring reliable power management. Various coil voltage options and suffixes (E for epoxy sealed, W for manual switch, K for PCB retaining stud, R for reverse polarity) are available to meet specific design requirements.
