Overview
The DLMZ Series DC Molded Case Circuit Breakers (hereinafter referred to as Circuit Breakers) are designed for use in DC power distribution networks, with a rated insulation voltage up to 1500V DC and rated current up to 800A. These circuit breakers are mainly used for distributing DC electrical energy and for providing reliable protection against overload, overvoltage, and short-circuit faults in DC circuits and power equipment.
Circuit breakers with a rated current of 630A and below can also be used for DC motor protection, offering dependable overload, undervoltage, and short-circuit protection for various industrial and renewable energy applications, including photovoltaic (PV) systems, energy storage systems, and DC distribution cabinets.
Under normal operating conditions, the DLMZ series can also be used for infrequent line switching and motor starting in DC systems.
According to their rated ultimate short-circuit breaking capacity, the circuit breakers are divided into three types:L-type (Standard Type), M-type (High Breaking Capacity Type)
The DLMZ Series DC MCCB provides excellent arc extinguishing performance, stable operation, and high reliability, making it an ideal choice for modern DC power protection applications.
