  • Modular automatic backup power transfer switch for generators (ATS) | 2P | 100A | 230V | 10kA | PC class | 50/60Hz

    Code: ES-LMS1-100GA

    Automatic резервe power transfer switch ATS, designed to automatically transfer the load between two power sources – the main electrical grid and a backup generator or inverter system. The device ensures that in the event of a main voltage failure, the electrical circuit is safely and quickly switched to backup power, and when the grid supply is restored, it is returned back automatically. This is a professional PC type automatic power transfer switch, developed for large single-phase loads up to 100A, featuring a high 10kA breaking capacity, long mechanical service life, and compliance with international standards.

    Functions

    Automatic mains and generator switching - the device continuously monitors the main power source. When voltage disappears or becomes unstable, the ATS automatically disconnects the mains and connects the generator or another backup power supply.
    Safe separation of two sources - the PC type construction ensures that both power sources never connect to each other. This is extremely important for generator protection and overall electrical installation safety.
    High 100A load capacity - suitable for controlling not only individual devices, but also the entire house main input, workshop line, commercial premises power supply, or larger electrical consumers.
    High 10kA breaking capacity - operates reliably even under higher inrush current surges, motor loads, or sudden grid disturbances.
    Overvoltage resistance - 8kV impulse voltage withstand helps protect the switching mechanism from sudden power surges.

    Application

    For household users: An excellent solution for residential houses, cottages, farmhouses, or garden houses where automatic heating support, water supply, security system operation, and uninterrupted lighting are important.
    For electricians/installers: The installer receives a professional standardized ATS unit, safe separation of two sources, reliable operation up to 100A, suitable for integration into distribution boards, generator cabinets, or automation panels.
    For engineers/designers: Suitable for designing backup power systems, automatic generator start circuits, critical load switching, and ATS panels for small industrial facilities.
    For business premises and farms: Solves one of the most important problems - business continuity when grid power supply is interrupted.

    Advantages

    Fully automatic power source switching
    Suitable for generator or inverter backup line
    High 100A rated current
    High 10kA breaking capacity
    PC type safe separation of two inputs
    Resistant to grid overvoltages up to 8kV
    Suitable for household and industrial use
    Certified according to CE and IEC standards
    Long mechanical service life
    Reduces losses caused by power outages

    Disadvantages

    Designed for single-phase systems, not suitable for three-phase facilities
    For fully automatic generator start, additional starting automation may be required (depends on generator model)
    Professional installation by a qualified electrician is recommended
    For larger systems with very sensitive electronics, additional protection modules may be used

    Does this device switch automatically when electricity fails?

    Yes, when the main power supply fails, the ATS automatically switches the power to the generator or another backup source. When electricity is restored, the system returns back to the main grid.

    Is this model suitable for a house?

    Yes, this 100A single-phase model is perfectly suitable for residential houses, cottages, garages, workshops, or other places where a backup generator is used.

    Is manual switching required?

    No, the entire switching function takes place automatically. The user does not need to physically operate any switches.

    Is this device difficult to install?

    Installation is not complicated for a qualified electrician, however due to the high current and the connection of two power sources, it is recommended that the connection be carried out by a specialist.
