A sub-distribution block and several phase distribution blocks are also available. The permissible voltages are up to 1000 V AC or 1500 V DC, and the currents range from 101 A to 353 A. Thanks to its 1500 V DC or 353 A ratings, the WPD 109 version is particularly suitable for photovoltaic systems.
In addition to modules certified according to IEC 60947-7-1, Weidmüller also offers variants that meet the requirements of UL 1059 for universal applications.
Weidmüller offers its new WPD distribution blocks in a wide range of combinations. For example, the multi-phase block allows for a variety of options. Expansions can be created by combining modules or forming bridges.
All WPD distribution blocks feature a compact, space-saving design. Thanks to their unique stepped shape and offset screw head position, WPD distribution blocks can be conveniently and securely connected to plant equipment or in confined spaces, regardless of the selected level.
WPD distribution blocks feature a halogen-free, self-extinguishing plastic housing with a V0 flammability rating according to UL 94 specifications. WPD distribution blocks also meet the contact safety requirements set out in EN 50274 and have a short-circuit withstand rating that complies with the stringent SCCR standard.
Its practical design and compatibility with the DIN TS 35 rail, according to EN 60715 and EN 50022 standards, facilitate easy and quick installation, even in difficult conditions.
The distribution blocks, which are the result of careful design, use highly visible signage labels to achieve clear identification of the equipment, thus ensuring order and safety in the control cabinet.
The following one- to three-pole modules or series are available: 1) WPD 100 sub-distribution block with a rated current of 100 A. 2) Phase distribution blocks with a rated current of 101 A: WPD 104 (single pole), WPD 204 (two poles), and WPD 304 (three poles). 3) Phase distribution blocks with a rated current of 125 A: WPD 105 (single pole), WPD 205 (two poles), and WPD 305 (three poles). 4) Single-phase distribution blocks: WPD 106 with a rated current of 160 A, WPD 107 with a rated current of 232 A, WPD 108 with a rated current of 250 A, and WPD 109 with a rated current of 353 A.
