ORDERING INFORMATION
• Code number: MD6P–24–[1][2][3]
Specify a code from below for each of [1] through [3].
(e.g. MD6P-24-00B)
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).
Line to line: ≤ 4 nsec.
[1] SAFETY APPROVAL
0: None
Line to ground: ≤ 20 nsec.
Leakage current:
3: FM explosion-proof
Line to line: ≤ 5 μA @ 30 V DC
Line to ground: ≤ 5 μA @ ±160 V DC
Discharge current capacity: 10000 A (8/ 20 μsec.)
Max. load current: 100 mA
4: ATEX flameproof
Confirm selectable combinations of approval and wiring
conduit types in the table.

Connect the MD6P’s green leadwire to the ground terminal inside the protected equipment enclosure to ground through the
enclosure’s outside ground terminal.
If the enclosure does not have an inside ground terminal, connect the green leadwire directly to the outside ground wire
pulled inside the enclosure. Keep the ground wire as short as possible.
