The 20525-84 is a 166ML series 10 Amp magnetic latching relay designed to control electrical loads. It features a DPDT contact configuration and is operated by a single 120 VAC coil with a nominal resistance of 1,850 Ohms and power consumption of 4.0 VA. The contacts are rated for 10 Amps at 120 VAC or 28 VDC, with a minimum electrical life of 100,000 operations. Its positive magnetic latch maintains the relay's status without continuous power, which is a key advantage. This compact, plug-in relay is well-suited for applications such as HVAC, laundry, and textile equipment where state memory is critical.
