SURGE PROTECTOR FOR PHOTOVOLTAIC SYSTEM
(750V DC,1000V DC USE)
Functions & Features
• Surge protection for photovoltaic array and power
conditioner.
• High discharge current capacity 20 kA
• Degraded head element is automatically separated from
the power lines by the incorporated thermal breaker, and
the LED lamp (turns off) and the relay contact alerts the
failure status.
• Breakdown of the surge protector remotely detected with
the alarm output
• Photovoltaic system's resistance to earth is measurable
without removing the SPD due to spark gap employed
between line and earth.

(100 V DC to operational votage), and turns off during
failure condition, power off and the thermal breaker
operating.

■ CONNECTION DIAGRAM
■ CIRCUIT BREAKER POSITION
If you want to use circuit breaker as SPD maintenance switch, insert a wiring MCCB for DC on SPD power side (diagram below).
Even when the output current of solar cell array is low, use 20 AT or more for wiring MCCB.

Wiring MCCB
*1. When the wiring distance is longer than 10 m between the power conditioner and the surge protector in the switch gear, install near the power
conditioner.
*2. Cable length between the branch point and the earthing: 0.5 m or less recommended
*3. When the solar panel manufacturer requires earthing at negative line of DC side, do NOT use the earth terminal of the MATPH but use the
L- terminal. If also, earthing at positive line is necessary, earth the L+ terminal.
