Lockable knob AK-PKZ0 030851

Locking knob for Eaton circuit breakers – reliable installation protection

This knob, known as AK-PKZ0, is an element used to lock Eaton PKZM0, PKZM4 and PKE series circuit breakers. It provides additional safety by preventing accidental switching on of the circuit breaker after it has been switched off – particularly important during maintenance or service work. The knob design allows it to be locked with a padlock with a shackle thickness of 3 to 6.35 mm, which further increases the level of security.

Functionality and practical application

The AK-PKZ0 knob is dedicated to Eaton motor disconnectors and circuit breakers. Its main task is to ensure safe and controlled switching off and locking of electrical circuits. This allows installers and end-users to be sure that the device will remain off throughout the work, minimizing the risk of electric shock or equipment damage. This is particularly important in industrial applications where safety is a priority.

Construction features and compatibility

The knob is made of durable black plastic. Its design allows mounting on PKZM0, PKZM4, PKZM0-T, PKM0, PKE and PKZ-SOL/P-SOL circuit breakers. Please note that the knob is not compatible with VHI20-PKZ0 devices. Simple installation and solid construction guarantee long-lasting and trouble-free operation. Using a padlock with an appropriate shackle thickness (3 - 6.35 mm) further strengthens the protection against unauthorized switching on of the circuit breaker.
