13.31是一個簡單的螺絲端子適用于接口應用線圈低壓單穩態繼電器（24 V）和負荷在供電網絡的電壓（230 V）。
繼電器提供了一個無AgSnO2觸頭額定12 250 V AC，并可在兩個版本-直流24伏和230伏交流電。
可以裝在接線盒或503盒改裝風格。

The 13.31 is a simple monostable relay with screw terminals suitable for interfacing applications where the coil is low-voltage (e.g. 24 V) and load is at the supply network voltage (230 V).
The relay offers a NO AgSnO2?contact rated 12 A 250 V AC, and is available in two versions - 24 V DC and 230 V AC.
Can be incorporated in junction boxes or retrofitted in 503 style boxes.
