Delixi Electric’s DZ47S series circuit breaker

Delixi Electric’s DZ47S series circuit breaker is a miniature circuit breaker (MCB) specially designed for lowvoltage terminal power distribution systems. It features overload protection, shortcircuit protection, and isolation functions, and is widely used in residential, commercial, and industrial fields. The following is a summary of its core information:

1. Product Positioning and Upgraded Features

DZ47S is an upgraded version of Delixi’s classic DZ47 series, with the main improvements including:

Enhanced breaking capacity: The entire series has a unified breaking capacity of 6kA, which is better than the 4.5kA specification of some competitors and can cut off shortcircuit current more reliably.

Expanded pole numbers: Two new combinations of 1P+N and 3P+N are added to cover singlephase and threephase power distribution scenarios, meeting different load requirements.

Optimized tripping curve: It provides Type C (instantaneous tripping at 510 times the rated current, suitable for lighting) and Type D (1014 times, suitable for impact loads such as motors), with a wider range of adaptation.

1. Comparison with Other Models
2. Comparison with the basic DZ47 version:

DZ47S adds 1P+N and 3P+N pole numbers, while DZ47 only has 1P, 2P, 3P, and 4P

The breaking capacity of DZ47S is uniformly 6kA, while some models of DZ47 are 4.5kA

DZ47S has a more modern appearance design and stronger accessory compatibility

2. Comparison with DZ47LE leakage type:

DZ47SLE integrates leakage protection function (residual operating current 30/50/100mA)

DZ47SLE is slightly larger in size (with an added leakage module) and has a higher price

The model should be selected according to whether leakage protection is needed

1. Selection and Usage Suggestions
2. Key points for selection:

Rated current: Calculate according to the load, and it is recommended to reserve a 20% margin

Tripping curve: Choose Type C for lighting/sockets and Type D for motors

Pole numbers: Use 1P/1P+N for singlephase loads and 3P/4P for threephase loads

Breaking capacity: It needs to match the shortcircuit current level of the installation environment (it is recommended to be ≥6kA)

2. sage precautions:

Avoid overload operation and check temperature rise regularly

Ensure firm wiring and meet the torque requirements during installation

In humid environments, it is necessary to cooperate with the sealing measures of the distribution box

Disconnect the upperlevel power supply when replacing to ensure safety

1. Core Influencing Factors
2. Pole number and current:

The more pole numbers and the larger the current, the higher the price. For example, the price of the 3P+N/63A model is about 58 times that of the 1P/16A model.

The tripping curve (Type C/Type D) has little impact on the price, and the price difference for the same specification is usually ≤10%.

2. Leakage protection function:

The price of the DZ47SLE series with leakage protection is significantly higher. For example, the 2P/32A/30mA leakage type is priced at 70.98 yuan, while the ordinary 2P/32A is only 15.52 yuan.

3. Accessory expansion:

The unit price of the shunt release (MX+OF) is about 8.0121.54 yuan, and the over/undervoltage release is about 18 yuan per unit.

Modular accessories can improve functions but require additional costs. For example, the total cost of a circuit breaker with a shunt release increases by about 2030%.

III. Purchase Channels and Strategies

1. Online platforms:

Official direct sales with transparent prices, and the promotional price of the DZ47SLE series is 114.44 yuan.

1. Suggestions for International Market Adaptation
2. North American market:

DZ47S has not obtained UL certification, it is recommended to choose Delixi’s CDB6i series (compliant with UL 489 standard).

2. Southeast Asian market:

DZ47S has passed CB certification, and the price is similar to that in China, with 1P/16A about 5 yuan and 3P+N/63A about 30 yuan.

1. Suggestions for Selection and Cost Control
2. Accurately match needs:

Choose Type C for lighting/sockets and Type D for motors to avoid cost increases due to redundant functions.

Prefer 1P+N over 2P to save space in the distribution box and costs (1P+N has a width of only 18mm and is 30% cheaper).

2. Accessory combination scheme:

The price of the shunt release (MX+OF) + circuit breaker set is about 4060 yuan, which is 15% cheaper than buying them separately.

The over/undervoltage protection function can be realized through the DZ47SGQR model, with a unit price of 42.28 yuan (original price 81 yuan).
