This is a Weidmüller ZQV 4/10 GE cross-connector (Order No. 1609030000), coloured yellow, with 10 poles and a rated current of 32 A (2-pole and multi-pole). It is explosion-tested, 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 31.6 mm deep, 59.3 mm high and 2.8 mm wide, and weighs 8.8 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, and its documentation includes a confirmation of standards to EN 45545-2:2020-10.
