Siemens 42AF35AJBSH Definite Purpose Contactor

Siemens 42AF35AJBSH is a Class 42 definite‑purpose, three‑pole contactor designed for reliable motor control in HVAC, pumping, and other equipment. It carries 25 A full‑load current (FLA) and 125 A inrush (LRA) on a 3‑phase circuit, and is rated to switch loads up to 600 VAC, making it suitable for mid‑range HVAC and process applications. This 42AF series DP contactor uses a 24 V AC coil for compact control and features welded silver‑cadmium oxide contacts, a reinforced polyester housing, and a durable metal back plate with interchangeable mounting; additional mounting options include DIN rail compatibility. Optional accessories such as snap‑on electrical or mechanical interlocks and a visual contact position indicator help ensure safe, verifiable operation. The device aligns with Siemens Furnas 42‑series and is commonly used where a dedicated definite‑purpose solution is specified, including air conditioning units, pumps and compressors, conveyors, and other equipment requiring reliable, low‑VA coil control in a 3‑pole arrangement.
