The DZ47Z series miniature circuit breaker is designed to protect DC circuits with a rated voltage of 750V and a rated current of 63A or less from overloads and short circuits in lines, lighting, and power equipment. Additionally, it can be utilized for occasional switching of lines and equipment in regular circumstances.
This product complies with the following standards: IEC60898-2 and GB/T14048.2.
The circuit breakers in this collection feature a plastic enclosure, overcurrent protection, operating mechanism, contact points, and arc suppression system. The casing is constructed from durable, fire-resistant plastic material. A multi-pole circuit breaker is created by combining individual single poles, with the protection mechanism linked by a connecting rod and the control handle linked by a covering, guaranteeing uniformity in the activation of each pole.
