Overview
The Zettler AZ2150-1A-24DE is an electromechanical power relay rated at 40A continuous current with a 24VDC control voltage. This miniature relay features SPST-NO (Single Pole, Single Throw – Normally Open) contact form and is designed for robust industrial switching applications. Meeting VDE, UL, and CUR standards, the AZ2150-1A-24DE provides reliable circuit control for panel-mount and PCB-mount designs in machinery control, HVAC, motor control, and power distribution systems.
Key Features
