DZ10 Series Molded Case Low Voltage Protective Circuit Breaker

The DZ10 series circuit breakers comply with the GB14048.2 standard and are designed for AC power distribution circuits operating at 50Hz, 400V or below, and currents up to 600A. They provide overload, undervoltage, and short-circuit protection, along with conventional low-frequency switching functionality. Featuring a thermoplastic insulating housing and a four-bar linkage operating mechanism, these breakers come with multiple tripping devices and offer both front and rear wiring configurations.

Suitable for distribution networks with AC frequency of 50Hz, voltage up to AC400V, and current up to 600A, used for distributing electrical energy, overload and under voltage, and short circuit protection of power lines and equipment, as well as for infrequent disconnection and connection of power lines under normal working conditions. This product complies with GB14048. 2 standard.

Product Features

The insulation base and cover are pressed with Thermoplastic.
The operating mechanism is a four link type.
The release is divided into multiple type (equipped with overload protection and short circuit protection), electromagnetic type (equipped with short circuit protection), and thermal release type (equipped with overload protection).
There are two types of wiring methods: front and back.
