Is connected between the battery and 12 V consumer. Protects battery as well as consumer from harmful undervoltage (consumer off at 10.7 V) and the connected consumer from harmful overvoltage (off at 15.5 V).
MT USG 40: With a separate switching output it is remote controllable and therefore usable as main control (all consumers off/on)
Switching Current Durance/Short: 40 A/60 A
MT USG 120: Function principle like MT USG 40, however with far higher switching voltage. In addition, an interior control can be plugged in, with which the vehicle can be made non-electric any time (battery main control).
Switching Current Durance/Short: 120 A/200 A
