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

0: None

Line to line: ≤ 4 nsec.

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.)

Max. load current: 100 mA

Confirm selectable combinations of approval and wiring

conduit types in the table.

Connect the Conduit Mount Type SPD’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.

To Equipment

Ground

*1. The zenor diode has polarity. Zero-cross signal cannot be connected.

*2. Use only when the signal line requires functional grounding.

This is NOT for surge protection.

Specifications are subject to change without notice.
