V7H3605 Siemens A & Vacu-Break Disconnect Switch Fusible Unit 600 V 400 A Fusible 3 Pole

Siemens low voltage circuit protection panel board/switch board units. Type: disconnect switch special features: VB panel unit, vacuum break fusible units for SB1, SB2 switch boards and f1, f2 panel boards application: industrial, construction voltage rating: 600 ampere rating: 400 number of poles: 3. Optional accessories auxiliary switch kit, compression lug adapter kit, terminal connector, T fuse adapter kit, shunt trip kit.

• Exclusive vacuum break clampmatic arc control - hazardous switching arcs are safely confined and controlled in the vacuum break chamber
• NEMA phasing - all line connections are phased as per NEMA standards, I.E., Left to right and top to bottom as you face the unit
• Pressure terminal connectors -suitable for aluminum or copper (100 amps and larger). All terminal connectors 200 amps and larger are removable
• Connection screws - bullet nosed for positive location and seating of screw
• Quick-make quick-break - assured by design of cam mechanism and powerful springs. Positive operation in “ON” or “OFF” position results from design of the cross arm and vacuum break head linkage
• Easy mounting - mounting feet have captive bullet nosed screws added, which seat quickly and positively, reducing installation time
• Padlocking member - provides easier locking of handle in the “ON” or “OFF” position
• Fiber end barriers - insulated end barriers prevent damage to wire during installation and are designed with openings large enough to accommodate removable wire grips (200 amps and larger units)
• High pressure spring reinforced copper fuse clips - provided extra pressure at the contact points fuse clips are removable from the front in 7 1/2” and 10” units and from the rear of 5” units
• Voidable cover interlock - permits only authorized personnel to void the door interlock and open door with switch “ON.” “Fool proof” mechanism will not permit door to be closed with handle in the wrong position
