DERLICN DZ47-63 Miniature Circuit Breaker is mainly used for AC 50Hz, rated voltage up to 400V, rated current up to 63A line for overload and short circuit protection, and also can infrequently turn on and off the electrical devices and lighting lines under normal conditions, but not for the protection of electric motors. DERLICN DZ47-125 Miniature Circuit Breaker ranges from 80A to 125A. Comply with standards: GB/T 14048.2, IEC 60947-2, CCC certification.
It’s an economical solution compared to moulded case circuit breaker (MCCB).
The smaller size is another advantage during the installtion.It can be installed on din-rail.The width is 1.5*standard modular width.

FAQ
Q1: Is it compatible with my existing circuit breakers? Are dimensions standard?
A: Yes. Standard modular design (18mm width per pole) fits DIN rails. All 1P/2P/3P/4P models are available for direct replacement – and only the current and poles need to be matched when replacing.
Q2: What is the breaking capacity of this DZ47 series miniature circuit breaker (MCB)? Are there any products with higher breaking capacity available?
A: The rated breaking capacity of DZ47 series miniature circuit breaker is 4.5kA, if you need higher breaking capacity, you can choose other series of our products, such as DZ65 series support up to 6kA breaking capacity, DL7 series support up to 10kA breaking capacity.
Q3: Do you have stock of all current ratings (6A-63A)? How to avoid wrong selection?
A: Yes, we have full range in stock. When selecting a model, please provide the power of the power equipment, or inform the type of load, our engineers will assist in confirming the specifications free of charge.
Q4: Can you provide samples?
A: Yes, we understand your concern for the first cooperation, so we can provide 1-2 free samples for you to test, but the shipping costs need to be borne by you.
Q5: What is the minimum order quantity (MOQ)? Do you support customised brands?
A: Regular models start from 100 pcs. We support customised logo (MOQ 500pcs), box or carton (MOQ 100,000pcs) and parameter labels (MOQ 500pcs, need to provide technical documents). The delivery period will be increased accordingly (please confirm the specific delivery time with our sales staff in advance).
Q6: Do you provide logistics tracking?
A: All orders are provided with full logistics single number, urgent needs can go by air (additional consulting freight).
Q7：How long is the product warranty? How to solve the faults?
A: The warranty is 18 months. Failure rate is less than 0.2%, if you receive a problem product, shoot a video + order number sent to the after-sales mailbox (info@derlicn.com), we will confirm the specific details with you within 48 hours to confirm that there is no error will send a replacement (no need to return the goods).
Q8: Can it be used for solar system or motor equipment?
A: Conventional DZ47 is suitable for AC power distribution. If it is used for motor protection, please choose the ‘D-curve’ (motor protection type), if it is used for PV DC system, you need to use special DC circuit breaker (stock/selection can be directly contacted our sales staff through the inquiry form).
Q9：How to pay? Do you accept letter of credit?
A: Support T/T, PayPal and so on. Specific payment methods can be confirmed with our sales staff.
Q10: Is there any exclusive discount for long-term bulk purchase?
