Commutador Masterswitch 0-10 kW - 2 entrades, 1 sortida

The Masterswitch 0-10kW automates 230V AC electrical distribution aboard your boat. It automatically switches between two separate power sources (e.g., a generator or shore power on one side, and an inverter on the other) to a single output, ensuring uninterrupted service without risk of short-circuit.

This model supports high power up to 10 kW and can handle a maximum output current of 40A at 230V.

It has two AC inputs (Input 1 typically dedicated to the dock or generator, and Input 2 for the inverter) and a single AC output to power your onboard electrical system.

No, unlike the "Masterswitch Fuses" version, this compact model does not include built-in circuit breakers. It is therefore essential to add external protection (magnetic-thermal circuit breakers and residual current circuit breakers) suited to your installation.

The transfer time via multipole relays is ultra-fast, ranging from 12 to 22 milliseconds for power-on and 4 to 19 milliseconds for power-off. This minimizes micro-interruptions for your electrical equipment.

It consumes approximately 7W when AC inputs are active. However, if it operates solely on the inverter (Input 2) with no other source available, it goes to neutral position and its consumption is 0W.

The housing is designed to be compact and easy to integrate. It measures 200 x 110 x 115 mm and weighs 1.3 kg.

Yes, it has an IP55 protection rating. This ensures excellent resistance to dust and water spray, making it perfectly suited for a marine environment.

No, this specific Masterswitch model is not compatible with Mastervolt's MasterBus communication system.

Input 1 (intended for shore power or generator) has absolute priority. If no voltage is detected on this input, the system automatically switches to Input 2 (inverter).

Input 1 has an adjustable delay of 0 to 10 seconds using a small screwdriver. The factory setting is set to 10 seconds to allow the generator set time to stabilize (voltage and frequency) before transferring the electrical load.

If you use Input 1 exclusively for a shore power inlet (without a generator), it is recommended to set the delay to 0 seconds so the transfer occurs immediately upon connection.

The Masterswitch terminal block accepts cables with a cross-section ranging from 0.5 to 10 mm² (AWG 20-7). For a rated current of 40A, it is recommended to use a 6 mm² or 10 mm² section depending on the length of your circuit and applicable standards.

Yes, to ensure the safety of your electrical installation, it is mandatory to integrate external fuses or circuit breakers as well as residual current circuit breakers on the wiring of all inputs and the output of the Masterswitch.

All grounding of power sources and consumers must be connected to the ground terminal (PE) of the Masterswitch. This terminal must then be connected to the boat's central ground (connected to the hull).

Yes, it is designed to operate optimally within a temperature range of -5°C to +60°C. It can therefore be installed in an engine room, provided that the room is properly ventilated and meets these tolerances.

Yes, the Masterswitch is a universal AC transfer switch. It is fully compatible with any 230V inverter on the market, provided the installation complies with marine electrical standards.

No, part number 55006015 is specifically designed for 230V (50/60 Hz) systems. If your boat is wired for 110V/117V, you will need to select a Masterswitch model rated for this voltage (such as part numbers 55106000 or 55106100).

The built-in delay on Input 1 is designed to postpone switching by up to 10 seconds. This effectively protects your onboard network from dangerous voltage and frequency fluctuations that occur during the generator's startup phase.

Yes, the transfer time is very fast. However, a 12 to 22 ms micro-interruption is unavoidable during physical relay switching. For highly sensitive computer equipment that may lose data, using a small uninterruptible power supply (UPS) in addition is recommended.
