ORDERING INFORMATION
• Code number: MD6N–24–[1][2][3]
Specify a code from below for each of [1] through [3].
(e.g. MD6N-24-00B)
Line to ground: ±160 V min.
Max. surge voltage
Line to line: 40 V max.
Line to ground: ±650 V max.
(The maximum voltage that could pass through the surge
protector. Protected equipment must be able to withstand
this voltage for a very short time period.)
Response time:
For the safety approval code 4, specify the product’s
destination country using Ordering Information Sheet (No.
ESU-8284).
[1] SAFETY APPROVAL

Line to ground: ≤ 20 nsec.
3: FM explosion-proof
Leakage current:
4: ATEX flameproof
Line to line: ≤ 5 μA @ 30 V DC
Line to ground: ≤ 5 μA @ ±160 V DC
Discharge current capacity: 10000 A (8/ 20 μsec.)
