BP520 - Burst plugs with indication

The BP520 series of pressure fuses have a "pop-up" indicator cap. A fine conductor passes through the construction of the fuse and the indicator cover of the part, which, when the fuse is activated or by emergency release of pressure, pushes out the fuse cover and thus disconnects (ruptures) the tested conductor. By breaking this wire, the communication in the monitored loop will be "opened". The indicators / controllers record this contact opening and provide further preset steps. Pressure fuses (also known as burst fuses) are designed to reliably release overpressure in the system in the event of an emergency.
