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 per Test Specification 109-1.
Test Requirements and Procedures Summary
Test Description
Voltage: 250 volts AC
Current: 6.5 amperes maximum
Temperature: -55 to 105°C
NOTE
The maximum rated current that can be carried by this product is limited by the
maximum operating temperature of the housings (105°C) and the temperature rise of the
contacts (30°C). Variables which shall be considered for each application are: wire size;
contact material; ambient temperature; and PCB design.
Meets requirements of product
