Přepínací skříň Masterswitch 25 kW (230 V)

It automatically switches between two alternating current sources (such as a generator and a shore power outlet) to power the onboard electrical system without any manual intervention.

This industrial transfer switch can handle high power loads up to 25 kW, with a maximum current of 125 A on both input and output.

The Masterswitch has two AC (alternating current) inputs for connecting your power sources, and a single output that redistributes the current to your electrical system.

Input 1 has absolute priority. If a voltage is detected, it automatically powers the output. Input 2 takes over only when no current is present on Input 1.

A delay (default set to 10 seconds) allows the generator to start and stabilize its voltage and frequency before taking the load, protecting your onboard electrical system.

Yes, this delay is adjustable from 0 to 10 seconds. If you use Input 1 to connect a shore power plug (which does not require a warm-up time), it is recommended to set this delay to 0 seconds.

The transfer time is extremely fast: expect 12 to 22 milliseconds on startup, and 4 to 19 milliseconds on shutdown.

Yes, due to the micro-interruption inherent in the transfer between AC sources, computers and other highly sensitive electronic equipment can lose data if not protected by a UPS.

Yes, it meets the IP55 waterproofing standard, providing effective protection against dust deposits and water jets in marine environments.

No, this specific model is not compatible with the MasterBus communication network.

Yes, this unit does not include circuit breakers. It is essential to install fuses and residual current circuit breakers (rated at a maximum of 125 A) on the wiring for all inputs and outputs.

The unit weighs 3.8 kg. Its exact dimensions are 291 x 241 x 168 mm (height x width x depth).

The grounding terminal of the Masterswitch must be connected to the boat’s or vehicle’s central grounding (connected to the hull or chassis) to ensure the safety of the installation.

The device is designed to withstand demanding conditions, with an operating temperature range specified from -5 °C to 60 °C.

It is designed for single-phase 230 V systems (with an acceptable input range of 200 to 250 V), operating at a frequency of 50 or 60 Hz.

No, this model is designed in a minimalist and industrial style: it has no LED indicators on the housing nor a connection port for a remote control.

Although it is rated IP55, it must be installed in a dry location, protected from direct rain, snow, excessive humidity, and condensation risks to prevent any electrical shock.

No, the Masterswitch is not intended to be used as a component in life-support systems or medical equipment, unless a specific written agreement with the manufacturer is in place.
