This is a single, T85 Diehl timer which has been used as a tanning bed timer for many different companys for over 2 decades. These were typically used for home or small commercial tanning beds, but can be used to trigger virtually any relay/contactor or any load at or below rating. (Note: the shown model is a max 20 minute timer. This is the 30 minute max version, which is virtually identical otherwise)
Unlike the MS65 timers, these are a purely mechanical timer, with no requirement for a neutral wire and use no electricity. These are sometimes known as "clicker timers" because of the distinctive clicking sound they make when timing down.
These have two separate poles that can be switched independently, allowing it to be used for US 220VAC-240VAC isolated switching.
