Victron SolidSwitch 104 70V 4A DC Load Switch

A small digital control signal can operate a larger DC load when a suitable switching device sits between them. The Victron SolidSwitch 104 is rated for loads up to 70V and 4A. It can switch resistive, capacitive, or inductive loads, including a contactor coil, within its stated limits.

The device is controlled by a low-power digital input, so the control circuit does not have to carry the load current directly. This arrangement is useful in electronic control or monitoring systems with a limited-output signal. The unit should be selected by both the voltage and current of the load being switched.

Victron specifically notes that the SolidSwitch 104 has no reverse-polarity protection and is not short-circuit proof. Those limitations matter when planning supply wiring and external protection. Correct input polarity and a properly protected load circuit are necessary for reliable operation. Browse more marine electrical switches at CritPro.
