描述

The AZ2100-1C-48DE is a miniature power relay manufactured by American Zettler, featuring a single Form C (SPDT) contact arrangement with 40 A switching capability and a nominal coil voltage of 48 VDC. This relay delivers robust performance with a maximum switched power of 900 W or 10,000 VA, maximum switched current of 40 A (Form A) or 30 A (Form B), and maximum switched voltage of 30 VDC or 300 VAC. The relay is rated for 10 million mechanical operations and 100,000 electrical operations at 30 A and 125 VAC resistive load, with an operate time of 8 ms typical and release time of 3.5 ms typical. It features AgCdO (silver cadmium oxide) contact material with initial contact resistance of =50 mO, operates over a temperature range of -55°C to 85°C (Class B coil) or -55°C to 105°C (Class F coil), and includes both PCB and quick-connect terminals for flexible installation. The relay is ideal for industrial control applications, HVAC systems, and refrigeration equipment where reliable high-current switching and long operational life are required.
