Vertical three pole fuse switches for fuses NH00 size.

• Distance busbars 185 mm.
• Rated operational current fup to 160A.
• Rated operational voltage up to 690 Vac.

Depending on the type of model, this range of fuse switches offers the option of single pole disconnection (DU), allowing individual disconnection of each phase, either with a fixed or retractable handle, or the option of three pole disconnection (DT), disconnecting all three phases simultaneously.

• Distance between busbars 185 mm or 210 mm.
• Rated operational current from 250 A to 1260 A.
• Rated operational voltage up to 690 Vac.

Depending on the type of model, this range of fuse switches offers the option of one pole disconnection (DU), allowing individual disconnection of each phase, either with a fixed or retractable handle, or the option of three pole disconnection (DT), disconnecting all three phases simultaneously.

• Compatible with switching solid links with NH2 and NH3 sizes.
• Rated operational current up to 400A in NH2 size and switching capacity up to 630A, 1000A and 2000A with different configurations in NH3 size.

Applications

Multifunctional solution for low voltage panel incoming purposes and busbar coupling among other applications.

A new accessory has been developed according to the IEC 60947-3 standard, which allows to increase the maintained short-circuit value up to 25kA/1s (rated short-time withstand current).
