EKM1-40N DPN type miniature circuit breaker (MCB) is a compact and efficient circuit protection device designed for low voltage electrical systems. It operates on the same basic principle as a standard circuit breaker, which is to interrupt the flow of current in an electrical circuit when a fault occurs, such as an overload or short circuit.
The working principle of a DPN type MCB involves a bimetallic strip and an electromagnetic coil. In the event of an overload, the bimetallic strip heats up and bends, causing the breaker to trip. In the case of a short circuit, the electromagnetic coil generates a strong magnetic field that quickly trips the breaker.
Compact size: DPN type MCBs are smaller than traditional circuit breakers, making them suitable for applications where space is limited.
Faster tripping: DPN type MCBs can trip more quickly in the event of a fault, providing better protection for electrical equipment and systems.
Ease of installation: DPN type MCBs are typically easier to install and replace than traditional circuit breakers, as they often feature plug-in or DIN rail mounting options.
Single pole + neutral (SPN) protection: DPN type MCBs provide protection for both the live (phase) and neutral wires in a circuit, offering enhanced safety compared to single-pole breakers.
Common use cases for DPN type MCBs include residential, commercial, and industrial applications where protection from overcurrents, short circuits, and other electrical faults is required. They are often used in conjunction with other circuit protection devices, such as fuses or residual current devices (RCDs), to provide comprehensive protection for electrical systems.
