The protection for the electric line FIAM AT6 is used for the protection of supply lines connected to remote control systems, remote alarm and tax measure. And 'built according to specific Italgas No. 706 and in compliance with CEI 64/8.

E 'available rated at 40, 200 and 300 VA, 220 V output

The protection consists of five stages:

• an input overcurrent protection
• an isolation transformer with grain oriented core, reinforced insulation, automatic thermal protection, short circuit proof, with the center of the screen and secondary earth
• an EMI filter
• two gas discharge tubes
• a double pole circuit breaker 30 mA, with a breaking capacity 4000 A

In this way there is the protection against electric shock is in common mode (through the insulation of the transformer), that the limitation of output current by the saturation of the transformer core. The isolation between the input and the stage of voltage limitation avoids the intervention of any differential protections located upstream of the apparatus.

And 'mounted in sealed metal box, size 300 x 205 x 145 mm.

Protection for power line FIAM AT11 is used for the protection of SCADA and remote monitoring FIAM TAL. And 'built according to specific Italgas No. 706 and in compliance with CEI 64/8.

E 'available rated at 40VA, 230V input, output 48 V

The protection system consists of three stages:

• overcurrent protection input
• an isolation transformer with grain oriented core, reinforced insulation, automatic thermal protection, short circuit proof, with the center of the screen and secondary earth
• two gas discharge tubes (embedded systems FIAM TAL)

In this way there is the protection against electric shock is in common mode (through the insulation of the transformer), that the limitation of output current by the saturation of the transformer core. The isolation between the input and the stage of voltage limitation avoids the intervention of any differential protections located upstream of the apparatus.

The AT11 is mounted in a protective plastic sealed box, size 150 x 220 x 100 mm.

The protection for telephone line AT5 FIAM is used for the protection of telephone lines connected to remote monitoring systems, remote alarm and tax measure.

And 'built according to specific Italgas N°. 705

The protection is constituted by four stages:

• Input overcurrent protection fuses are special high power of interruption
• two gas discharge tubes 10A / 10 KA on the input terminals
• three gas discharge tubes after the fuses
• two limiting resistors
• three varistors downstream resistance
• three spark gaps needle

In this way there is the protection against electric shocks is also significant quantities of both towards the ground and in common mode.

And 'mounted in sealed metal box, size 300 x 205 x 145 mm.

Smaller version of the protection AT5, no spark, plastic sealed in box size 150 x 110 x 100 mm.
