Combined protection device against transient and permanent surges to associate an emission coil (trigger) with a cutting device (IGA) or molded box, in three-phase systems.
The operation of this protection module is to produce a disconnect signal to the general cut-off switch, general automatic switch (IGA) or molded box, when it is subjected to a higher voltage than it had to receive, in a continuous way and to ground the transient surges caused by lightning drop or the switching of electrical distribution lines.
This device, very compact and simple installation, provides very high protection, both against transient or permanent surges, as well as line, by incorporating an IGA (MCB circuit breaker) with a cutting power of 10kA. It has a visual indicator of cutting status.
The supply does not include the MCB circuit breaker, nor the emission coil, only the surge protector.
