Key Features of Sofielec Electrical Circuit Breakers

  • Bimetal and Magnetic Trip Design—Overload and Short-Circuit Protection

    Consistent tripping starts with careful assembly and setup. Sofielec assembles the bimetal parts, sets the thermal trip, and adjusts the magnetic unit to keep trip action steady across different current levels. B, C, and D curves serve different loads. Each trip unit is matched to its load type to reduce false trips while still giving the level of protection the circuit needs.

  • Arc Chamber Design—Safer Fault Breaking

    A short circuit creates a strong electrical arc. If that arc is not controlled, it can burn the contacts, heat the case, stop the breaker from opening, or create a safety risk. Sofielec uses a multi-plate arc chamber. The arc guide and contact gap help stretch, cool, and put out the arc faster, which supports safer fault breaking.

  • DIN Rail and Busbar Design—Made for Different Distribution Boxes

    Standard DIN rail mounting keeps installation simple. Depending on the series, Sofielec units can work with pin busbars, fork busbars, or other busbar types for different panel designs. A firm clip helps each unit sit straight. Standard module sizes also reduce mounting errors during batch assembly, helping customers build distribution boxes with better speed and fit.

  • Silver Alloy Contact Joining—Stable Switching and Fault Breaking

    Contacts do the hardest work inside a breaker. Sofielec uses silver alloy contacts and joins them to current-carrying parts by welding or riveting to form a strong connection. A stable contact keeps resistance lower. It also reduces contact wear and supports reliable switching during frequent use and when the breaker must clear a fault.

Quality Control for Low Voltage Circuit Breakers —Required Checks Before Shipment

Quality Control for Low Voltage Circuit Breakers —Required Checks Before Shipment

A breaker is a safety part. Its real value appears during overloads, short circuits, leakage faults, and other abnormal conditions, when dependable trip action matters most. Quality checks cover every main production stage. Sofielec checks raw materials, part assembly, mechanism settings, trip action, and final units, then selects test items for each product type and standard.
