AMBOHR 100KA 4P 385Vac Type 1 / class I / Class B
High power surge protector
Type 1 surge protectors are heavy duty devices, designed to be installed at the origin of the AC installations equipped with LPS (Lightning Protection System). They are necessary to protect sensitive equipment connected to AC network against direct and indirect effects of lightning.
AM-B100 AC surge protectors are designed to be connected in multi-pole configuration to protect single-phase, 3-phase and 3-phase+Neutral AC networks, sometimes associated with a dedicated N/PE SPD. This SPD is particularly useful in a high lightning density area where the risk of heavy surge current or even direct strike is high (eg: buildings equipped with lightning rods).

In order to test its products internally for standards compliance and to evolve toward greater reliability AMBOHR has several test sites equipped with :
• Material for test environment (damp heat, climate, shock)
• HT digital Oscilloscope fast
• Wave generators current up to 100 kA - 8/20µs
• Current waveform generators up to 100 kA - 10/350
• 1.2/50-8/20µs hybrid wave generators up to 20 kV/10 kA
• 400 Vac three phase low voltage network-Icc 1.5 kA / phase for coupling with pulsed current
The G100K test generator can produce exceptionally high impulse current of 100 kA and is used for testing structural lightning protection systems as well as Type 1 surge protectors.
