The BRKLOV0009 is the 16-amp member of the Lovato DC breaker family used in Tornatech GPD diesel fire pump controller panels, occupying the CB1–CB2 positions on the electrical drawing. These breakers protect the controller's DC battery circuits, opening automatically if current exceeds the 16 A rating.
A breaker that trips as soon as it is reset, will not latch, or feels loose in its mounting should be replaced rather than forced. If tripping is repeated, check the downstream circuit for shorts before installing the new breaker: de-energize the DC circuit, transfer the wiring, and confirm the breaker holds under normal load.
