Bypass switch for frequency inverter 16-63A

Ensure continuous operation and safe maintenance of ventilation units.

KATKO’s bypass switch for variable frequency drives (VFDs) is designed to ensure continuous operation of ventilation units during drive maintenance or fault situations. This makes it a reliable choice for ventilation control applications where downtime is not an option.

Key Benefits:

• Continuous operation – ventilation keeps running even when the drive is out of use, and the switch prevents power feed to the drive during bypass operation.
• Easy maintenance – the drive can be safely disconnected and serviced without interrupting operation.
• Efficient installation – includes all necessary cable entries (cable glands), and wiring can be made quickly and directly to terminal blocks.
• EMC-protected design – delivered as a standard EMC-compliant solution.
• Optional motor protection switch – enhances motor safety and overall reliability.
• Durable sheet steel enclosure – a robust, long-lasting solution for ventilation unit applications.

Other Features:

• Available in polycarbonate (IP65), sheet steel (IP65) or aluminium (IP66) enclosed solutions.
• R.M.S value 50kA
• Padlockable with three locks
• Door interlock with defeat mechanism
• Tested according to IEC 60 947-3
• CB certificates
• Cover texts available in multiple language versions
• Note! Al-cables cannot be connected directly to switch terminals. For Al-cable connection please use a bi-metal cable connector, available here.

KATKO’s bypass switch is engineered to ensure reliable and safe operation of ventilation units in all conditions.
