Main characteristics of circuit breakers
The main characteristics of circuit breakers include: rated voltage Ue; rated current In; tripping current setting range of overload protection (Ir or Irth) and short-circuit protection (Im); rated short-circuit breaking current (industrial circuit breaker Icu; household circuit breaker Icn), etc. Rated operating voltage (Ue): This is the voltage at which the circuit breaker operates under normal (uninterrupted) conditions

How many types of relays are there?
Electromagnetic relay: An electric relay that works by using the attraction force generated between the electromagnetic iron core and armature in the input circuit. (2) Solid-state relay: A relay in which electronic components perform their functions without mechanical moving parts, and the input and output are isolated. (3) Temperature relay: A relay that operates when the ambient temperature reaches a given value.

How to check the safety of imported wires and cables
High-quality imported electrical wires and cables offer greater safety and can withstand high temperatures. They are also cold-resistant, ensuring reliable performance in both summer and winter. This prevents disruptions to electricity supply and guarantees better electricity usage in all conditions. 2. They have a longer lifespan. Generally, good quality electrical wires and cables from reputable manufacturers can last for up to ten years or even longer. This makes them convenient and reliable, eliminating the need for frequent replacements. This saves a lot of trouble and resources. Manufacturers of safer electrical wires and cables produce products that are more popular...

A circuit breaker is a switching device that can make, carry, and break currents under normal circuit conditions, and can make, carry, and break currents under abnormal circuit conditions within a specified time. Circuit breakers are divided into high-voltage circuit breakers and low-voltage circuit breakers according to their scope of use. The boundary between high and low voltage is relatively vague; generally, those above 3kV are called high-voltage electrical appliances...
