FAQs

This model is designed for mounting plate assembly use. Begin by attaching the unit to the plate, then connect 4–95 mm² conductors to the box terminal, route cables via the top or bottom outlets, and secure the assembly in the enclosure. Ensure the 3-pole, 00 NH arrangement is maintained and verify torque specs for the terminals to maximize reliability.
It is rated for 160 A at 690 V, 3-pole configuration, NH size 00, with a box terminal connection for 4–95 mm² conductors. Dimensions are 106 mm wide by 194 mm high, and the unit weighs about 0.76 kg per pack with copper weight around 0.15 kg per piece.
UR suitability may vary; data notes indicate UR applications are possible only in conjunction with Special Purpose Fuses. If UR usage is required, confirm compatibility with the specified UR fuse family and verify that any additional protective fuses meet the system’s safety requirements.
The product aligns with IEC/DIN EN 60 947-3 for its electrical performance, and the material provides UL 94 fire protection. Additional classifications include ETIM 7.0 EC001040 and ECLASS 8.0 27371401, aiding cross-system procurement and cataloging.
Key factors include mounting-plate compatibility that speeds installation, top/bottom cable outlets for flexible routing, and clamping area designed for laminated copper bars (13 × 13 mm). The robust copper-to-silver contact tracks and UL 94 flame rating also contribute to lower fault rates and longer service intervals.
