It sits between the battery bank and the inverter: the handle opens the circuit safely for maintenance or an emergency, while the NH fuse links inside protect against short circuit and overload.\u003c\/p\u003e\n \u003cp\u003eThis version is \u003cstrong\u003etwo-pole\u003c\/strong\u003e (Jean Müller code T100112002, designation KETO-1-2\/F): two poles, exactly what DC asks for, one on the positive and one on the negative. The \u003cstrong\u003eNH1\u003c\/strong\u003e links are not included and should be chosen on the battery’s real charge and discharge current with a safety margin: the range runs from 35A to \u003cstrong\u003e250A\u003c\/strong\u003e, which is the body’s rated current.\u003c\/p\u003e\n \u003cp\u003eJean Müller rates it at \u003cstrong\u003e690V AC\u003c\/strong\u003e and, on DC, \u003cstrong\u003e250V per pole\u003c\/strong\u003e, reaching \u003cstrong\u003e440V DC\u003c\/strong\u003e with the poles in series.
