Siemens has built The VBII Safety Switch to be so durable,so reliable - it just might be around for the next millennium. In fact, The VBII gives you the confidence that once it is installed, you're done!

Features:
• Rugged metal handle with large red grip which
• provides highly visible ON/OFF indication.
• Generous wire gutters that meet and/or exceed
• NEC wire bending space requirements.
• A unique enclosure design that adds rigidity
• and strength. It also offers a touch-safe edge
• for the installer's hand.
• Visible blade, double-break switching action.
• Spring reinforced fuse clips that assure reliable
• contact for cool operation.
• Front removable mechanical lugs that are
• field convertible to copper mechanical
• lugs or compression (crimp) connectors.
• A hinged clear line shield with proble holes
• for inspecting or testing line side terminals.

Features:
• Soft starting and smooth ramp-down
• Stepless starting
• Reduction of current peaks
• Reduced load on the power supply network
• Reduction of the mechanical load in the operating mechanism
• Avoidance of mains voltage fluctuations during starting
• Considerable space savings and reduced wiring compared with conventional starters
• Maintenance-free switching

Performance range:
• Up to 900 HP (at 460 volt) inline circuit
• Up to 1600 HP (at 460 volt) inside-delta circuit

In addition to soft starting and soft ramp-down, the solid state 3RW44 softstarters provide numerous function for higher-lever requirements. The new torque control and adjustable current limiting enable the high-feature soft starters to be used in nearly every application. They guarantee the reliable avoidance of sudden torque applications and current peaks during motor starting and stopping. This creates savings potential when calculating the size of the switchgear and when servicing the machinery installed.

The bypass contacts already integrated in the softstarter bypass the thermistors after a motor ramp-up is detected. This results in a further reduction in the heat loss occurring during operation of the softstarter.

Combinations of various starting operating and ramp-down possibilities ensure an optimum adaptation to the application specific requirements.
