The AZ2100-1A-15DEF is a miniature power relay designed for switching applications requiring high current capacity and reliable contact performance. It features a single Form A (SPST-N.O.) contact arrangement with a maximum switching current of 40 A and a nominal coil voltage of 15 VDC (must operate at 11.25 VDC, maximum continuous 22.5 VDC). The relay offers a coil resistance of 256 O ± 10% and delivers an operate time of 8 ms typical (15 ms maximum) with a release time of 3.5 ms typical (10 ms maximum). With a mechanical life expectancy of 10 million operations and electrical life of 100,000 cycles at 30 A and 125 VAC, combined with dielectric strength of 2500 VRMS (coil to load contacts) and an operating temperature range of -55°C to 85°C (Class B coil), this relay is well-suited for industrial control, HVAC systems, and general-purpose switching applications where durability and performance are essential.
