DZ47-63 CE Certified Miniature Circuit Breaker MCB for Overload and Short Circuit Protection

We've been shipping these DZ47-63 units for years, and what it does is provide solid overload and short circuit protection for residential and light commercial panels—the Type C trip curve handles lighting circuits fine, but if you're dealing with motor starts, go with Type D or you'll get nuisance tripping.

Breaking capacity sits at 4kA or 6kA depending on the pole count, and mechanical life is 10,000 operations, which basically means it'll outlast most installations. The housing is flame-retardant PA66 nylon, so it won't melt into a puddle if something goes wrong upstream.

You'll need to specify pole configuration (1P, 2P, 3P, or 4P) and current rating when ordering—common picks are 16A, 32A, and 40A, but we stock the full range from 6A up to 63A. Terminal capacty goes to 25mm² cable, which is tighter than some competitors, so check your wire gauge before buying.

CE and CB certifcation are standard, and our company provide COAs with each shipment; ISO9001 and CCC are also in place for the Chinese market. Payment terms are typically 30% deposit with the balance before shiping, and lead time runs about 20 days or so for standard orders—confirm stock if you need faster.

Mounts on standard 35mm DIN rail, operating tempearture range is -5°C to +55°C, and it's rated IP20 so keep it inside a panel. Also, the trip indicator is a simple red flag that pops out—pretty obvious when it's tripped, but don't rely on it for remote monitoring without a separate signal contact.

Not ideal for high-inductive loads like large transformers without derating—the breaking capacity isn't there for extreme fault currents. Most procurement people order in multiples of 100 units to hit the MOQ, but our company can negotiate for smaller trial batches if you're testing a new design.
