Schneider Electric VCCF01 Vario 20 A Emergency Stop Switch

VCCF01: TeSys Vario emergency stop switch disconnector, 20 A

The VCCF01 is the 20 A member of the TeSys Vario emergency stop switch disconnector series, one step below the VCCF0. The datasheet lists it as a TeSys Vario switch disconnector of the VCCF type with three poles and three normally open contacts, supplied as three parts: the switch body, the shaft extension and a red rotary handle on a yellow front plate. The switch sits at the back of the enclosure on a rail or plate and the handle is fixed on the door, so the operator reaches the disconnect without opening the cabinet. Seven Star LLC supplies the VCCF01 in Oman and the GCC as an independent supplier in Muscat.

The conventional free-air thermal current is 20 A and the enclosed thermal current is 16 A, and that second figure is the one to compare with your load when the switch is inside a closed panel. The unit is suited to a very small machine or auxiliary feeder: a dosing pump panel, a small fan or a laboratory unit where the motor draws only a few amperes.

TeSys Vario VCCF series around the VCCF01

The eight references in this group share the same concept, a rear-mounted switch with an extended door handle, and move up through the thermal-current ladder. The row for the VCCF01 is highlighted.

Endurance and site conditions for the VCCF01

The mechanical durability is 100000 cycles and the electrical durability is 100000 under AC-21 and 30000 cycles under DC-1 to 5. The intermittent duty class is 30. These numbers describe how often an operator can use the handle over the life of the switch; for an emergency stop that is rare, but the same switch used as a daily disconnect uses its cycles faster.

The operating ambient is -20 to 50 °C and the datasheet gives IP20 for the switch and IP65 for the handle. In an Oman installation, remember that a panel standing in the sun in the Gulf summer can exceed the cabinet ambient limit, so measure the temperature inside, not outside. The VCCF01 is typically found in pump houses, desalination and water-treatment skids, process plants and building plant rooms with dust and heat.

VCCF01 technical specifications

Mounting and padlocking the VCCF01

The datasheet lists the mounting support as the handle on the door and the switch on a symmetrical rail or on a plate, fixed by clips for the rail and by screws for the plate; the handle is held by four screws. The base measures 60 x 60 mm and the body is 74 mm high and 60 mm wide.

The handle accepts 1 to 3 padlocks 4 to 8 mm, and its marking is 0-1. Padlocking in the OFF position is the usual lock-out routine for maintenance; agree the lock-out procedure with the site safety team before the panel is released. The 60 mm base frame keeps the cut-out and the space behind the door small, which suits compact machine panels.

Current, power and fault ratings of the VCCF01

In utilisation category AC-23 at 400 V the datasheet lists a rated operational current of 11 A. For motor duty in category AC-3 it lists 3 kW at 230 to 240 V, 4 kW at 400 to 415 V, 5.5 kW at 500 V and 7.5 kW at 690 V, and 5.5 kW at 400 to 415 V in category AC-23A.

The switch can make 200 A and break 200 A at 400 V in AC-21A, AC-22A and AC-23A. Its conditional short-circuit rating is 10 kA at 400 V when it is protected by a 20 A aM or gG fuse, and the short-time withstand is 300 A for one second. The rated impulse withstand is 8 kV.

Because the conditional rating depends on the 20 A fuse, treat the fuse as part of the product selection: a larger fuse, or none, is not covered by the datasheet figure.

Details to send with an RFQ for the VCCF01

A short request is enough. If the VCCF01 is a replacement, tell us whether the handle, the shaft extension and the switch are all needed, because the datasheet describes them as a set.

• Part number VCCF01 and quantity.
• Supply voltage, frequency and prospective short-circuit current.
• Motor or load rating, and the upstream fuse rating.
• Door thickness and enclosure depth where the handle is fitted.
• Certification and delivery requirements.

Selection checklist for the VCCF01

• Load current: stay inside 16 A enclosed thermal current for the real panel conditions.
• Motor power: 4 kW at 400 to 415 V in category AC-3 is the figure for direct motor duty.
• Fuse: the 10 kA conditional rating assumes a 20 A aM or gG fuse upstream.
• Cable: up to 10 mm² solid or 6 mm² flexible with end sleeve, torque 2.1 N.m.
• Door and panel: base 60 x 60 mm, handle on the door, switch on rail or plate.
• Certification need: the datasheet lists CSA; CCC; GL; UL; UKCA; tell us if the project demands another.
