The UDB 2X25/16 BU trunk line branch terminal supports the alignment of up to three terminal blocks, ensuring efficient connectivity and organization in electrical installations. With a nominal voltage rating of 400 V and a maximum load current of 101 A, this terminal facilitates reliable connections.

Connection is achieved through a screw method, with a primary rated cross section of 25 mm², accommodating conductor cross sections ranging from 1.5 mm² to 25 mm². The device also features a second-level screw connection for wire sizes between 1.5 mm² and 16 mm². The mounting type is compatible with NS 35/7.5 and NS 35/15 rails, and the product is colored blue (RAL 5015) for easy identification.

In terms of technical compliance, this terminal adheres to IEC 60998-1 standards, with an overvoltage category of III and a degree of pollution rated at 3. The rated surge voltage is 8 kV, and the maximum power dissipation under nominal conditions is 3.26 W. Its dimensions include a width of 23 mm, height of 46 mm, and depths of 42 mm on NS 35/7.5 and 49.5 mm on NS 35/15.

Additional specifications include a minimum stripping length of 16 mm, a tightening torque of 1.7 to 2 Nm, and a flammability rating of V0 according to UL 94. The terminal operates effectively within a temperature range of -60 °C to 110 °C, ensuring functionality in diverse environments.
