AC220V Screwless Terminals Thermal Stress Tester Plug Socket Test Equipment
Plug Socket Test Equipment Screwless Terminals Thermal Stress Tester IEC 60884-1
Standard:
IEC 60884-1 2013 ‘Plugs and socket-outlets for household and similar purposes -- Part 1: General requirements’ clause 12.3.11
Application:
Screwless terminals shall withstand the electrical and thermal stresses occurring in normal use.
This device is use to check whether the screwless terminals can withstand the electrical and thermal stresses occurring in normal use. Plug Socket Test Equipment
Test sample:
Screwless Terminals. Plug Socket Test Equipment
Feature:
Loading the screwless terminals for 1 h with an alternating current as specified in table 10 and connecting rigid solid conductors 1 m long having the nominal cross-sectional area as specified in the same table. Then measure the voltage drop.
