Troubleshooting

Padlock does not fit the MZN175

Verify that the padlock shackle diameter is within the 1mm to 7mm range specified for the MZN175.

MZN175 is difficult to attach to the circuit breaker

Ensure the circuit breaker is in the OFF position and that the MZN175 is correctly aligned with the breaker's operating lever before attempting to clip it on.

Locking mechanism feels stiff or jammed

Clean the mechanism and apply a small amount of dry lubricant. Avoid using oil-based lubricants which can attract dust.

MZN175 does not prevent the breaker from being switched ON

Confirm that the MZN175 is fully closed and the padlock is securely locked through the mechanism. Ensure it is correctly engaged with the breaker lever.
