FAQs：

Q1: What are the primary protection functions of the DZ47LE series residual current circuit breaker?

A: . DZ47LE series is designed to provide three-in-one protection for electrical circuits. It protects against earth leakage (personal electric shock protection), overloads, Ve short circuits. It is applicable to circuits with a rated voltage of 230V or 400V (50Hz) and a rated current up to 63A.

Q2: Does the DZ47LE series comply with international or national safety standards?

A: Yes. The DZ47LE series residual current circuit breaker complies with the GB/T 16917.1 standard. This standard specifies the requirements for residual current operated circuit breakers with overcurrent protection for household and similar industrial applications.

Q3: What is the rated short-circuit breaking capacity of the DZ47LE series?

A: The DZ47LE series features a rated short-circuit breaking capacity of 6kA. This ensures the device can safely interrupt fault currents up to 6000 Amperes, maintaining system integrity in residential and commercial distribution boards.

Q4: What is the difference between Type C and Type D trip curves in the DZ47LE series?

A: . Type C trip curve (5~~10In) is engineered for distribution protection, suitable for resistive and inductive loads with low inrush currents. The Type D trip curve (10~~20In) is designed for motor protection and other equipment with high starting currents, preventing nuisance tripping during startup.

Q5: Which pole configurations are available for the DZ47LE series?

A: To meet various wiring requirements, the DZ47LE series is available in multiple pole configurations, including 1P+N, 2P, 3P, 3P+N, and 4P. This allows for both single-phase (230V) and three-phase (400V) electrical system integration.

Q6: What are the rated residual operating currents (sensitivity) for this series?

A: The DZ47LE series offers two standard sensitivity levels: 30mA and 50mA. The 30mA setting is the standard for personal electric shock protection, while the 50mA setting is typically used in environments requiring slightly lower sensitivity to avoid leakage-related tripping on longer cable runs.

Q7: How do the DZ47LE-32 and DZ47LE-63L models differ in terms of current rating?

A: . DZ47LE-32 is designed for lower power branch circuits with rated currents of 6A, 10A, 16A, 20A, 25A, and 32A. The DZ47LE-63L is a higher-capacity version for main lines or heavy-duty equipment, supporting 40A, 50A, and 63A.

Q8: Is the DZ47LE series residual current circuit breaker suitable for 3-phase industrial loads?

A: Yes. When configured as a 3P, 3P+N, or 4P device, the DZ47LE series is suitable for 400V 3-phase systems. It is commonly used for motor protection and industrial distribution where residual current protection is required alongside overcurrent safeguarding.

Q9: What is the installation method for the DZ47LE series?

A: The DZ47LE series is a miniature residual current circuit breaker designed for standard 35mm DIN rail mounting. This ensures compatibility with most modular distribution boxes and industrial enclosures used by contractors and switchgear manufacturers.

Q10: What is the Minimum Order Quantity (MOQ) for wholesale procurement of DZ47LE breakers?

A: For B2B procurement and wholesale supply, the MOQ for the DZ47LE series is 144 units. This bulk packaging is optimized for electrical wholesalers, engineering firms, and industrial suppliers participating in large-scale building projects.
