Terminal Block Line with Screw Clamp Fuse Blocks

The ABB Low Voltage Products division has expanded its SNK series of terminal blocks by introducing the new ZS10-SF screw clamp fuse blocks, offering the highest electrical ratings and the most compact design available in the industry. At only 8mm (0.315") wide the new fuse blocks provide the slimmest protection available for 6.3 x 32mm (1/4" x 1 1/4") fuses, with electrical ratings of 600 V and 22 A, and a wire range of 24 - 6 AWG. The ZS10-SF blocks are closed, requiring no end section. The fuse is safely mounted without touching any active parts by simply snapping the fuse into the hooks on the fuse holder door. When the door is closed the fuse is securely connected. The new line complements the existing SNK ZS4-SF blocks which offer 5 x 20mm (0.197" x 0.787") and 5 x 25mm and (0.197" x 0.984") fuse protection.

ZS10-SF fuse blocks are available with or without blown fuse indication, and in an easy disconnect model. They have two jumper channels and accept the same jumpers and markers as standard ABB SNK terminal blocks, reducing the number the parts required for assembly and inventory stocking.

There are three specific ZS10-SF fuse block models:

·      ZS10-SF: the standard non-indicating model.

·      ZS10-SF-R: featuring a blown fuse indicator to quickly identify defective circuits: o   ZS10-SF-R1 (24 - 110V)

ZS10-SF-R3 (115 - 250V)

·      ZS10-SF-R2: features a disconnect lever for simplified disconnect operations. The disconnect lever is easily operated by hand, and wiring of the alternated disconnect and fuse circuit is simplified.

The ZS10-SF line is especially suited for the HVAC, lift, food and beverage, and traction infrastructure equipment markets. The complete SNK line is available through certified ABB channel partners.
