Automatic circuit breakers

Buy circuit breakers for reliable electrical protection

Circuit breakers are a key safety element in any electrical system, from household outlets to industrial equipment. They are designed to automatically shut off power supply in the event of overloads or short circuits, preventing damage to expensive equipment, fires, and electric shock. The Svet-Expert online store offers a wide selection of circuit breakers that guarantee stable and safe operation of your electrical network.

When choosing a circuit breaker, it is important to consider a number of technical parameters to ensure maximum efficiency and reliability of protection:

• Rated current (A): Determines the maximum permissible load that the circuit breaker can withstand without tripping.
• Tripping characteristic (B, C, D): Indicates the speed of the circuit breaker's response to excess current (for resistive, inductive or highly inductive loads).
• Number of poles: From 1P (single-phase) to 4P (three-phase with neutral), depending on the type of network.
• Breaking capacity (kA): The maximum short-circuit current that the circuit breaker can safely disconnect.
• Manufacturer: Selection of products from trusted Brands ensure durability and compliance with standards.
