Manual Transfer Switch, 50 Amp 120V/240V AC Dual 2-Pole DIN Rail Mount RV Transfer Switch, Single-Side Interlock Circuit Breaker MTS D2P C50

Buen producto, construción de calidad y bien diseñado.

This twin breaker is well made and includes the mounting hardware. Breaker works exactly as advertised and both breakers can’t be on at the same time. I’m using the breaker to toggle 110v AC power between 2 sources. This allows me to choose whether a battery powered converter or shore power will power my RV. I highly recommend this breaker if you want a manual transfer switch for RV power.

Does a great job.

I installed this in my boat to separate shore power from an inverter system I installed. When I saw the. Advertisement it was exactly what I was looking for. My only concern was what the advertisement shows as load is listed on the device as L1 and L2. In the electric field L1 and L2 are always your line or incoming power not the load. I did test it and seems to function as it should. Maybe the symbols are different due to the design of two power sources feeding one output because now L1 And L2 are feeding whatever you’re powering up from one source or the other. Otherwise this was perfect.

Working Reconmended

I wasn't sure if this would work but it ended up being exactly what we needed. We have an outside 240 volt cable that connects directly to a generator during storm. This allow for safely switching the power source from main breaker box to the generator without back-feeding power onto the outside power grid. There is a dedicated 15 amp breaker box that sits inline between this transfer box and the air conditioner. If you need a transfer switch for a single dedicated outlet (either 120v or 240v) between two different power sources and safety is a priority, this might be exactly what you need. Even if this matches your amperage, I would not rely solely on the breakers in this box but would recommend an additional external dedicated breaker of the required amperage added inline to prevent power surges.

funciono ok

For lower amperage circuits this is a good solution for switching power sources, or could be used divert power from one machine to another.
