What Equipment is DZ40LE RCBO Mainly Applied?

I. DZ40LE RCBO Core Application Scenarios and Devices

1.Household and commercial power distribution systems

• Conventional electrical protection: It is used for air conditioners (40A specification is common), water heaters, high-power kitchen appliances and other equipment that require leakage protection, to prevent electric shock accidents caused by leakage.
• Main switch/branch protection: It serves as the main leakage protection switch for distribution boxes in households or small shops (63A specification), or provides protection for independent circuits such as lighting and sockets (16A-32A specification).

2. Industrial equipment and special loads

Electric tools and motors: Protect mobile devices prone to electric leakage such as electric drills and cutting machines, and support C-shaped trip curves (to prevent instantaneous current surges).

3. Safety protection in special environments

In damp areas such as bathrooms and pump rooms, high-risk zones should be equipped with 30mA high-sensitivity leakage protection (as per standard requirements).

Medical equipment: Some models (such as Type A or Type A+S) are suitable for medical electrical equipment and can detect pulsating DC leakage.

III. DZ40LE Installation and Safety Specifications

It must be operated by a certified electrician: For electrical installations, power must be cut off and insulation protection measures taken.

Match line load: Avoid failure to operate in case of overload or short circuit. For example, for the 40A specification, a ≥6mm² wire should be matched.

Regular testing: RCBO comes with a built-in test button (T button), and the reliability of the action needs to be checked monthly.
