Přepínač Masterswitch 0–10 kW – 2 vstupy, 1 výstup

The Masterswitch 0-10kW automates the 230V AC electrical distribution aboard your boat. It automatically switches between two distinct power sources (for example, a generator or a shore power inlet 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 usually dedicated to the harbor 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. Therefore, it is essential to add external protection (magnetic-thermal circuit breakers and residual current circuit breakers) suitable for your installation.

Transfer time via multipolar relays is extremely fast, ranging from 12 to 22 milliseconds for ignition and 4 to 19 milliseconds for shutdown. 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) without any other power source available, it defaults to neutral position and its consumption drops to 0W.

The unit 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 splashes, which is perfectly suited to a marine environment.

No, this specific Masterswitch model is not compatible with the MasterBus communication system from Mastervolt.

Input 1 (intended for the dock 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, set using a small screwdriver. The factory setting is fixed at 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 connection (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 cross-section depending on the length of your circuit and the 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 (RCCBs) on the wiring of all inputs and the output of the Masterswitch.

All grounding connections for power sources and consumers must be connected to the Masterswitch ground terminal (PE). 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 it is properly ventilated and complies with 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 networks (50/60 Hz). If your boat is equipped for 110V/117V, you will need to select Masterswitch models dedicated to this voltage (such as part numbers 55106000 or 55106100).

The built-in delay on Input 1 precisely delays switching by up to 10 seconds. This effectively protects your onboard network from dangerous voltage and frequency variations that occur during the generator start-up phase.

Yes, the transfer time is very fast. However, a micro-break of 12 to 22 ms is unavoidable during the physical switching of the relays. For highly sensitive IT equipment that risks losing data, using a small uninterruptible power supply (UPS) in addition is recommended.
