Schneider Electric 3-Pole Panel Mount Isolator Switch -, IP65, 41.5A, 22 kW

Schneider Electric VARIO Series Isolator Switch, 41.5A Switching Current, IP65 - VBF3

This isolator switch provides safe manual disconnection for three-phase systems in industrial control panels and on-door installations. It is intended for preventive maintenance and isolation duties, offering a robust rotary handle for clear ON/OFF operation and suitability for both AC and DC networks within typical plant environments.

Features & Benefits

• 41.5A operational current delivering stable load switching
  690V rated operational voltage for high-voltage applications
  22kW switching power enabling medium-power motor control
  IP65 enclosure rating allowing use in dusty or wet conditions
  Screw clamp terminals accepting up to 25mm² conductors
  Padlock compatibility for secure isolation during service

Applications

• Suitable for door-mounted isolation of control panels in factories
  Ideal for three-phase motor isolation in machinery rooms
  used with switchgear requiring padlockable safety isolation
  Suitable for maintenance isolation in automation cabinets
  Used for isolating distribution circuits in harsh environments

What Terminal types and conductor sizes are supported?

Power connections use screw clamp terminals that accept solid conductors up to 25mm² and flexible cables with ferrules up to 16mm² when tightened to 4N·m.

How does the handle support secure lock-out procedures?

The rotary handle accepts 1 to 3 padlocks with shackle diameters of 4 to 8mm, allowing compliant lock-out during maintenance.

What mechanical and electrical endurance can be expected?

The mechanism is rated for 30,000 mechanical cycles and 30,000 electrical cycles under AC-21 and DC-1 to 5 duty classes.

What environmental and safety conditions does it tolerate?

It operates between −20 to 50°C, withstands vibrations (10 to 150Hz, 1gn) and shocks (11ms, 30gn), and meets an 8kV impulse withstand rating.

Which short-circuit characteristics are relevant for protective device coordination?

It has a rated conditional short-circuit current of 10kA at 400V with associated 63A aM or gG fusing and a making capacity up to 630A at 400V.

Notes

The figures quoted for rated operational power within the price table are with respect to a voltage of 230/240V, with figures within brackets ( ) being those with respect to a voltage of 690V.
The higher current rating refers to use in free air, the lower current rating represents use in an enclosure.
