DS503E-230
Part Number: 64024
- Type 1 + 2 unipolar surge protector
- Iimp total: 100 kA on 10/350µs impulse
- Imax : 140 kA on 8/20µs impulse
- Internal disconnections, status indicators
- Remote signaling
- IEC 61643-11, EN 61643-11 and UL1449 ed.4 compliance
The DS500E range of surge protectors are Type 1 + 2, very high power, they are intended to be installed at the entry of the Low Voltage installation.
They are used to protect single-phase, three-phase or three-phase + Neutral networks in common mode or in common and differential mode.
The 'Multi-Varistor' technology used allows the best possible behavior for the LV network (no follow-on current).
The DS500E range is installed on a DIN Rail and has a double connection for the active conductor, which allows an optimized connection to the network.
