Unlike a DC isolator, which must switch both the positive and negative wires, an AC isolator should be selected based on whether the supply is single phase, as is common in home installations, or three phase, as is common in commercial or industrial installations. A 2pole isolator should be used to switch the live and neutral … Read more
What is a DC Fuse? A DC Fuse is an electrical protection device employed to interrupt the flow of current in order to prevent fires or equipment damage when a circuit becomes overloaded or experiences a short circuit. It stands as a pivotal safety apparatus, commonly utilized within electrical systems, ensuring that currents remain within safe parameters. … Read more

1P, 2P, and 1P+N circuit breakers are types of circuit protection devices used in electrical systems to prevent overcurrent and protect against electrical faults. Each of these breakers has specific applications and characteristics: 1P Circuit Breaker (Single-Pole): A 1P circuit breaker is designed to provide protection for a single conductor or one phase of an electrical circuit.It is commonly … Read more
What is Surge Protective Device? Surge Protective Devices (SPDs), also known as surge protectors or lightning arrestors, are devices designed to protect electrical and electronic equipment from voltage spikes or surges, which can be caused by lightning strikes, electrical faults, or other factors. There are three main types of SPDs: Type 1, Type 2, and Type … Read more
