Eaton’s one-port low-voltage surge protective device delta models SPD120480D3M, SPD160480D3M and
SPD200480D3M meet the requirements of IEC 61643-11 / EN 61643-11, Part 11: Test Class II, and are
intended to be installed in applications with a degree of protection rated IP 20.
The delta models are intended for use with a three-phase TN-S system with PE and neutral distribution, 5
conductor with a minimum 10 AWG or 6 mm
2
. The delta models are also intended for use with a three-phase
TN-C system with PEN distribution, 4 conductor with a minimum 10 AWG or 6 mm
2
. Screws used for
connection to ground shall be #10-32 x 3/8” and shall not be zinc or aluminum. This product is not serviceable
and contains no replacement parts..
Additional product information and ratings for IEC applications:
• The SPD contains internal disconnects with a short circuit current rating I
SCCR
of 200kA.
• Residual current IPE for this product is 5 mA.
• Operating temperature is normal -5°C to 40°C (23°F to 104°F).
• Humidity range is 5% through 95% non-condensing.
• The SPD may be mounted directly to earthed conductive surface, installed as per this manual.
