Product Information
Full details
The Schneider Electric Vario VCF4 is a 3-pole disconnector designed for industrial applications, serving as both a main switch and an emergency stop. It is ideal for control panel builders and maintenance engineers who require a reliable and robust isolation device. Its key benefit is providing safe and compliant electrical isolation, with a caveat that its 80A rating requires careful consideration of load conditions. This device offers a 690V maximum operating voltage and 80A continuous current rating, featuring front mounting with a turn button and screw connections for secure integration.

FAQs
What is the maximum power the VCF4 can control?
The VCF4 is rated for 57A at 400V for AC-23 (motor loads), which corresponds to approximately 30kW. For AC-21 (resistive loads), it can handle up to 80A.
Can this disconnector be used outdoors?
The front face offers IP65 protection, making it resistant to dust and low-pressure water jets. However, it should be installed in a suitable enclosure to protect the rear connections and the overall assembly from direct environmental exposure.
How do I engage the padlock feature?
The VCF4 supports padlock engagement directly on the control knob mechanism to ensure the switch remains in the OFF position, preventing accidental activation.
What type of connections does the VCF4 use?
It uses screw connections for the main circuit, allowing for secure termination of power conductors.
What is the warranty period for the VCF4?
The Schneider Electric Vario VCF4 comes with a warranty period of 1.5 years.
Is this device suitable for DC circuits?
The VCF4 is designed and rated for AC circuits (AC-23 and AC-21). It is not intended for use in DC applications.
What are the dimensions of the VCF4?
The package dimensions are approximately 85mm (depth) x 120mm (width) x 80mm (height).
Troubleshooting
Device will not switch ON/OFF
Verify that the padlock is not engaged. Check that the control knob is correctly aligned and turning freely. Ensure power supply is present and within operational voltage limits.
Overheating at terminals
Confirm that the connected conductors are of appropriate gauge for the 80A rating. Re-tighten screw terminals to the recommended torque specification. Ensure the load current does not exceed the device's rated continuous current for the applied voltage.
Poor contact or intermittent power
Inspect internal contacts for debris or damage. Ensure the device is securely mounted to the panel. Verify that the load is not exceeding the AC-23 rating if applicable.
IP65 seal compromised
Check the integrity of the front panel gasket. Ensure no foreign objects are obstructing the mechanism. Avoid high-pressure water jets directly at the device.
Pros and Cons
Pros
- Robust and reliable for industrial environments.
- Dual functionality as a main switch and emergency stop enhances safety.
- High current and voltage ratings accommodate significant loads.
- IP65 rating provides good protection against environmental factors.
- Padlockable feature ensures secure isolation.
- Clear and intuitive front-mounted operation.
Cons
- Specific continuous current rating (57A at 400V for AC-23) needs careful verification against load requirements.
- Requires panel modification for front mounting.
- Operating temperature limit of +50°C may restrict use in extremely hot environments.
- 1.5-year warranty is shorter than some competitors.
Setup, Compatibility & Care
Setup:
The VCF4 is designed for front panel mounting. Ensure the panel has the appropriate cutout for the turn button control and the main body of the disconnector. Connect the main circuit conductors to the screw terminals, ensuring proper torque is applied for secure connections. For emergency stop functionality, ensure the device is wired according to relevant safety standards and local regulations.
Compatibility:
This disconnector is suitable for AC power systems with a maximum operating voltage of 690V. It is rated for 80A continuous current (AC-21) and 57A at 400V (AC-23). Ensure the connected load does not exceed these ratings. It is compatible with standard control panel enclosures and wiring practices.
Care:
Regularly inspect the device for any signs of damage or wear. Keep the front panel and operating mechanism clean. Ensure connections remain tight. The IP65 rating applies to the front face; ensure the enclosure's rear is adequately protected. No lubrication is typically required for the mechanism.
