Buchholz relay - NM series

Buchholz relays of the NM series allow continuous and analogue gas volume measurement so that accumulated gases in the relay are detected early on, information can be gathered about the generation of the gases, and it is easier to analyze the fault at an early stage. The cap of the terminal box accommodates the electronic amplifier of the measuring unit.
