商品説明These in-line thermostats are available in 100 to 250 Vac or the low voltage models of 12 to 24 Vdc. Easy to use. The thermostats come with cable ties for mounting. They also close on fall. The high voltage units FGT305, FGT306 and FGT 307 have a bi-metal snap action. The low voltage units, FGT302 and FGT303 have a creep action. The creep action is a device which will slowly make or break the contacts of the bi-metal element. This results in a constant temperature with very small differentials.
