This is a Weidmüller ZQV 4N/20 GE cross-connector (Order No. 1909020000) from the W-Series, coloured yellow, with 20 poles and a rated current of 32 A (stated for both 2-pole and multi-pole connection). It is designed for direct mounting onto the terminals, made of Wemid material with a UL94 V-0 flammability rating, plugged in with a pitch of 6.1 mm. It measures 25.7 mm deep, 120.7 mm high and 2.8 mm wide, and weighs 14.06 g. Storage temperature is -25°C to 55°C, with a continuous operating temperature range of -60°C to 130°C.

Plug-in cross-connections offer easy handling and quick installation, saving time during installation compared with screwed solutions. Due to stability and temperature reasons, only 60% of the contact elements can be broken out; using the cross-connector reduces the rated voltage to 400 V, and to 25 V if a cut cross-connection with blank cut edges is used. The product is RoHS compliant without exemption. Its own datasheet notes that this article will no longer be available (available until 2021-12-31), with Order No. 2883800000 listed as the alternative product.
