FEATURES
■
CURRENT CAPACITY
• The one-port SPD can be used regardless of the load cur-
rent.
■
HIGH PERFORMANCE & RESPONSE TIME
• The discharge element (zinc oxide varistor) between the
lines does not disturb the power line with follow current
normally observed by a spark gap after a discharge. The
response time is also very high.
■
HIGH DISCHARGE CURRENT CAPACITY
• The MATP is designed to withstand 20 kA or 40 kA surg-
es (test waveform 8/20 µsec.). High design standard com-
pared to normally induced surge current level of 1 kA.
■
THERMAL BREAKER
• The power supply voltage is continuously applied to the
incorporated discharge element (zinc oxide element).
Degraded element is automatically separated from the
power lines for safety to prevent overheating caused by
leakage current.
• The failure is notified visually by the monitor LED and
remotely by an alarm contact.
■
PREVENTING ELECTRIC SHOCK
• The MATP’s terminal section with a terminal cover has
IP20 protection level to protect from an electric shock.
• The MATP is designed for use with ring shape solderless
terminals for a wide range of wire sizes from 2 to 14 mm

DIN RAIL MOUNTING
The MATP is mounted on a 35-mm-wide DIN rail. Set the
MATP so that its DIN rail adaptor is at the bottom. Posi-
tion the upper hook at the rear side of base on the DIN rail
and push in the lower.
When removing, push down the DIN rail adaptor utilizing a
minus screwdriver and pull.
