The CHAA4 Series is a 35A/40A automotive relay with 1 Form A or 1 Form C contact arrangements, designed for applications such as ABS control, fan, door, and fuel pump systems. It operates at 12VDC or 24VDC coil voltages with a nominal coil power of 1.2W for D variants and 1.4W for R variants. The relay features silver alloy contacts, supports switching up to 560W at 14VDC, and offers mechanical endurance of 10,000,000 operations and electrical endurance of 100,000 operations under rated load. It has a 10ms maximum operate and release time, insulation resistance of 100MΩ min, and dielectric strength of 500VAC between coil and contacts. The enclosure is either vented (dust-protected, RTI) or sealed (wash-tight, RTIII), with QC terminals and an approximate weight of 19g. Operating temperature ranges from -40°C to +125°C, with humidity tolerance of 20% to 85% RH.
