What is an automatic transfer switch?
What is an automatic transfer switch? An automatic transfer switch (ATS) is a device that automatically transfers a power supply from its primary source to a backup source when it senses a failure or outage in the primary source. Following the failure, the ATS automatically invokes the backup so...Read more -
Isolating switch’s function
An isolating switch’s primary function is to provide electrical isolation for safety during maintenance, repairs, or emergencies by physically disconnecting a circuit from its power source, creating a visible and certain break in the circuit. It ensures the circuit is de-energized, preven...Read more -
What Is An MC4 Connector?
MC4 connectors are single-contact electrical connectors. They are commonly used for connecting solar panels. MC4 stands for “Multi-Contact, 4 millimetre”. It is a standard in the renewable energy industry. An MC4 connector enables the easy construction of strings of panels. In today’s solar marke...Read more -
Voltage protector function
A voltage protector safeguards electrical equipment by monitoring incoming voltage and automatically disconnecting power when the voltage goes outside a safe, preset range (too high or too low). After the voltage stabilizes and returns to normal levels, the device automatically re-establishes the...Read more -
Application And Type of Digital Timer Switch
Types of Digital Timer Switches Daily Timer Switches As the name suggests, daily timer switches allow you to set on and off times that repeat every day. These are great for applications where you want your devices to turn on and off at the same time each day, such as lighting or heating systems. ...Read more -
How distribution boxes work
A distribution box works by receiving a single electrical power input and splitting it into multiple, independent branch circuits that power different parts of a building. Inside,circuit breakers or fuses act as safety devices, monitoring each circuit’s power flow and automatically “...Read more -
What is a Digital Time Switch?
In our modern, fast-paced lives, we’re always looking for ways to simplify our routines and save time and energy. Have you ever wished you could automatically turn your lights on and off at specific times, or have your coffee maker start brewing before you even get out of bed? That’s where digita...Read more -
The Functions And Roles of Relays
A relay is an electronic component that uses electromagnetic principles or other physical effects to achieve the “automatic on/off” of circuits. Its core function is to control the on-off of large current/high voltage circuits with small current/signals, while also achieving electrica...Read more -

Drop out Fuse Tips What is a dropout fuse?
01 Working Principle of Drop-Out Fuses The core working principle of drop-out fuses is to utilize overcurrent to heat up and melt the fuse element, thereby breaking the circuit and protecting electrical equipment from damage. When an overload or short circuit occurs in the circuit, the fault cu...Read more -
Differences Between MCCB and MCB
Miniature circuit breakers (MCBs) and molded case circuit breakers (MCCBs) are both important devices in electrical systems used to protect against overloads, short circuits, and other faults. Although the purpose is similar, there are still some differences between the two in terms of capacitanc...Read more -
what is distribution box?
A distribution box (DB box) is a metal or plastic enclosure that serves as the central hub for an electrical system, receiving power from the main supply and distributing it to multiple subsidiary circuits throughout a building. It contains safety devices like circuit breakers, fuses, a...Read more
