20A Mini Breaker DZ47-63

DZ47 – 63 miniature circuit breaker is applicable to the lighting power distribution system (Type C) or the power distribution system for motors (Type D). It is mainly used in circuits with an alternating current of 50Hz, a rated voltage of up to 230V and 400V, and a rated current ranging from 1A to 63A to provide overload and short – circuit protection. Meanwhile, it can also be used to intermittently switch off electrical devices and lighting circuits under normal conditions. Compliance standards: GB10963.1, IEC 60898 – 1

As a core protection and control component in low-voltage power distribution systems, miniature circuit breakers (MCBs) are widely used in various electrical scenarios due to their compact design, reliable performance and easy operation. Their core advantages can be summarized into the following six categories:

Introduction

The product we are going to introduce today is our miniature circuit breaker, with an overall size of only 7.76.51.7 cm. Its compact size makes it easy to install.
The current rating (A) of this type of miniature circuit breaker ranges from 6A to 63A, and the rated voltage is 5-220V.
As a core protective device in low-voltage power distribution systems, the miniature circuit breaker works on the principle of overload protection and has a wide range of applications.
This model of miniature circuit breaker not only enables AC control but also has a DC version available. If you need a miniature circuit breaker for AC-to-DC applications, please contact us for customization.
