The DS150E is a Heavy Duty Type 1 AC Surge Protector Device (SPD) designed to be connected at the entrance of the electrical installation. This SPD provides an efficient protection against direct and indirect effects and is particularly useful in a high lightning density area where the risk of heavy surge current or even direct strike is high (e.g. : buildings equipped with lightning rods).
The DS150E is a one-pole SPD and can be used in common mode (DS150Es connected between L/PE and N/PE) or common and differential mode (DS150Es connected between L/N and 1 x DS100EG between N/PE).
This SPD is designed to withstand a 15 kA lightning current (10/350 μs impulse). It is based on «multi-MOV» diagram : this technology allows a very discharge capability and the best behaviour possible on AC network (no follow current).
To meet standards, the DS150E includes a thermal disconnection mechanism, fault indicator and an internal microswitch for remote signaling.
The SPD is DIN rail compatible and is featured with a double terminal for line wire to allow improved connection to the AC network.
