Performance and Test Description
Product is designed to meet the electrical, mechanical and environmental performance requirements
specified in Figure 1. Unless otherwise specified, all tests shall be performed at ambient environmental
conditions.
Test Requirements and Procedures Summary
Test Description
Voltage: 600 volts AC
Current: See Figure 4 for applicable current carrying capability. Maximum rated current that can
be carried by this product is limited by maximum operating temperature of the housings (105° C)
and temperature rise of the housings (30° C). Variab les to be considered for each application are:
wire size, connector size, contact material, ambient temperature, and printed circuit board design.
Temperature: -55 to 105° C
Meets requirements of product
