Lightning Surge Protectors for
Electronics Equipment M-RESTER
ONE-PORT SURGE PROTECTOR
BETWEEN NEUTRAL AND PROTECTIVE EARTH
Functions & Features
• Designed to protect electronics equipment from induced
lightning surges with gas discharge tube
• One-port surge protector according to IEC61643-1
• Connected between neutral and protective earth
• High discharge current capacity of 40 kA (8/20 μs)
• Protect against overvoltage between N and PE caused by
earth fault
• No interruption of power supply even when the head
element is removed: easy maintenance and replacing
• Degraded head element is automatically separated from
the power lines to prevent overheating, with a relay contact
output to alert the failure status.
• Head-base connection is keyed so that only a head
element of correct line voltage can be mounted.
Typical Applications
• Protection between N and PE of TT system
• Low-voltage distribution board
• Combination with installation for large load current

*1. The circuit breaker must be installed. Molded-case circuit breaker (MCCB) or residual current circuit breaker with overcurrent protection (RCD) can be used.
The rated interrupting capacity of the circuit breaker must be greater than the highest amount of current that could be available in the circuit.
Install MCCB (rated current 20 – 30A) that has element for each phase. Or RCD with protection from nuisance tripping against transit voltages type or time-delay
overcurrent protection type is recommended.
Recommended sensitivity current rating: 30mA
*2. Cable length between the branch point and the earthing: 0.5 meters or less recommended
*3. The protected device's metal enclosure must be cross-wired to the earth terminal of the MAKN. If the protected device has no earth terminal, earth only the MAKN.
*4. In order to protect an electronic circuit such as measuring equipment or communication equipment, we recommend to use surge protectors which have serial
impedance incorporated such as M-System's models MAX, MMA or MAH.
■INSTALLATION EXAMPLES
When power supply side (N) and equipment side (PE) are earthed independently (TT system), installs this unit between N and PE. Install one-port
surge protector for power supply (model: MAKF) between L to L and L to N. The installation procedure of the three-phase/4-wire system is shown
below as an example.

■ALARM OUTPUT
When the alarm output is to be transmitted remotely via outdoor cables, a surge protector for the signal line is required.
Choose a circuit breaker with alarm output. Configure a logical OR sequence so that the alarm trips when both or either
of the MAKF, MAKN or the breaker alarm trips.
