The AZ2150-1A-110D is a 40A miniature power relay designed for high-reliability switching applications. It features a 110 VDC nominal coil voltage with a maximum continuous rating of 163.2 VDC, a coil resistance of 13,450 O (±10%), and a must-operate voltage of 82.5 VDC. The relay employs silver cadmium oxide contacts with a contact resistance of less than 20 milliohms initially, rated for 40 A Form A (NO) switching at 250 VAC for 6,000 cycles or 30 A at 125/240 VAC for 100,000 cycles. It offers Class B insulation standard (130°C maximum) with an optional Class F (155°C) version, mechanical life expectancy of 10 million operations, and electrical life of 1×105 cycles at 30 A 120 VAC. The relay meets UL 508 Group A spacing and UL 873 refrigeration requirements, features a Proof Tracking Index (PTI/CTI) of 175, and is available with an epoxy seal for automatic wave soldering and immersion cleaning. Common applications include industrial control, refrigeration systems, and safety control circuits where reliable high-current switching and long operational life are essential.
