Bosch D122 Dual Battery Harness

Dual Battery Harness. The D122 Dual Battery Harness protects the installer and the battery when connecting two batteries, in parallel, to compatible control panels. The D122 eliminates the hazards of batteries connected in parallel by utilizing a thermal circuit breaker to govern the circuit. The positive side of the harness is in series with the circuit breaker. It breaks the electrical circuit of the second battery when the thermal rating is exceeded. This prevents the battery circuit from creating a potentially harmful current overload condition.
