AMERICAN ZETTLER AZ21511C48D Power Relay

This power relay features a 48 VDC coil voltage, SPDT contact configuration, and a current rating of 20 amps. It is designed for PCB mounting, operates as a single side stable relay, and is not sealed. Classified as Class B with a 1/16 inch clearance. It is suitable for switching resistive loads up to 20A at 250VAC and 15A at 125VAC, with a maximum switching power of 600 VA. The relay supports a life expectancy of 100,000 operations for resistive loads and meets UL and VDE standards for safety and reliability. It features silver cadmium oxide contacts with resistance less than 20 milliohms, ensuring low contact resistance and efficient switching in industrial applications, with a typical operate time of 8 ms and release time of 3.5 ms. Its operating temperature range is from -55°C to 125°C for Class F, making it suitable for high-temperature environments. The relay weighs 25 grams and has a dielectric strength of 2500 Vrms contact to coil.
