PERFORMANCE
MODEL: MD6T–24–[1][2][3]
Discharge voltage (peak voltage)
Line to line: 30 V min.
ORDERING INFORMATION
• Code number: MD6T–24–[1][2][3]
Specify a code from below for each of [1] through [3].
(e.g. MD6T-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
0: None
Line to line: ≤ 4 nsec.
Line to ground: ≤ 20 nsec.
4: ATEX flameproof
Leakage current:
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
[2] WIRING CONDUIT
0: G 1/2 (Not selectable for ATEX flameproof approval)
1: 1/2 NPT
Internal series resistance: Approx. 22 Ω including return
Max. line voltage
2: M20 × 1.5
Without safety approval: 30 V DC
With safety approval: 28 V DC
Capacitance @ 1 kHz:
[3] BODY MATERIAL
B: Brass
S: Stainless steel
Line to line: ≤ 2500 pF
Line to ground: ≤ 100 pF
CAUTION
The packing of the cable gland must be separate from the

Connect the MD6T’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.
