Combination with accessories

Core Functions

Overload protection function: It monitors the load current in real time. When the current exceeds the safe rated value due to equipment overload (e.g., excessive connected devices), the function triggers quickly to cut off the circuit, preventing overheating of wires or components and avoiding damage or fire risks.

Short-circuit protection function: It responds instantly to short-circuit faults (caused by wire insulation damage, etc.). Once a short circuit occurs (with extremely high current), the function acts immediately to disconnect the circuit, safeguarding the power supply system and connected equipment from severe damage.

Product Features

Dedicated DC arc-extinguishing technology: It efficiently suppresses and extinguishes arcs generated during DC circuit breaking. This avoids arc burning of contacts, ensures stable breaking performance, and extends the product’s service life while enhancing operational safety.

Wide range of voltage and current ratings: The product covers multiple voltage (e.g., low to medium DC voltages) and current specifications. It adapts to diverse application scenarios (such as industrial DC power supplies, new energy systems), reducing the need for multiple product models and improving versatility.

Main Application Areas

Solar photovoltaic power generation systems: Protecting solar panel series/parallel circuits and the outputs of DC combiner boxes.

Energy storage systems (ESS) and battery banks: Protecting charge and discharge circuits of lithium batteries, lead-acid batteries, etc.

Electric vehicle charging infrastructure: Used for internal circuit protection in DC charging piles.

Rail transportation and marine power systems: Protecting DC power systems used in trains, subways, and ships.
