DZ47-63 2-Pole MCB 6A–63A 400V Mini Circuit Breaker DIN Rail

DZ47-63 2-Pole Mini Circuit Breaker (MCB) – 6A to 63A | 400V | 35mm DIN Rail

The DZ47-63 2-Pole Mini Circuit Breaker (MCB) is a CE-certified, compact protection device designed for residential and light commercial electrical installations. Available in a wide range of current ratings — 6A, 10A, 16A, 20A, 25A, 32A, 40A, 50A, and 63A — this Type C breaker delivers reliable overcurrent and short-circuit protection on single-phase AC circuits operating at 50Hz/60Hz and rated up to 400V.

With a robust 6KA breaking capacity and standard 35mm DIN rail mounting, it integrates seamlessly into most residential distribution boards and industrial control panels. Both the live and neutral wires are simultaneously disconnected during a trip event, providing an added layer of electrical safety.

Frequently Asked Questions

Q: What is the difference between a Type C mini circuit breaker and other trip curves?

A: A Type C MCB trips between 5–10 times the rated current, making it well-suited for circuits with motors, transformers, and inductive loads that draw higher inrush currents on startup. Type B breakers trip at lower multiples and are better for purely resistive loads. The DZ47-63 Type C breaker is a versatile choice for mixed residential and light commercial applications.

Q: What amperage rating should I choose for my circuit?

A: Select an amperage rating that matches or is slightly above the maximum continuous current draw of the circuit you are protecting, while remaining within the safe current-carrying capacity of the installed wiring. For example, a 2.5mm² cable typically supports up to 16A–20A, while 6mm² cable can support up to 32A. Always consult a qualified electrician to confirm the correct rating for your specific installation.

Q: Is this MCB compatible with standard DIN rail enclosures?

A: Yes. The DZ47-63 is designed to snap onto a standard 35mm DIN rail, making it compatible with the vast majority of distribution boards, consumer units, and industrial control cabinets that use this rail width.

Q: Does the 2-pole breaker disconnect both live and neutral conductors?

A: Yes. The 2-pole design simultaneously disconnects both the live (phase) and neutral conductors when the breaker trips, providing a higher degree of isolation and electrical safety compared to single-pole alternatives.
