OEM 2 Pole DC MCB stands for original equipment manufacturer. It is a device used to protect electrical circuits from overloading or short-circuiting.

This device is designed to automatically detect a fault condition and disconnect the circuit to prevent any damage or injury. It is typically used in low-voltage applications such as solar photovoltaic systems, electric vehicles, and other industrial applications.

When the current flowing through the circuit exceeds the rated current, it triggers an internal mechanism that trips the switch and interrupts the current flow. This helps to prevent damage to the circuit and potential hazards such as fires or electrical shocks.

Typically, a unit has a rated current and voltage, a breaking capacity, and tripping characteristics. Materials and workmanship depend on the manufacturer.

In this way, you are guaranteed that your OEM 2 pole DC MCB is high-quality and you are confident about branding it with your business name.
