Top 3 Customer Questions & Concerns �
� Why does this switch have a 30A rating compared to standard 15A switches?
This switch is specifically designed with reinforced internal contacts to prevent arcing and overheating when used with high-current motors or heating elements. A standard 15A switch may melt if used on a device pulling 20A or more; this 30A model provides a significant safety margin for heavy machinery.
Is this switch illuminated?
While some KCD4 models feature internal lamps, these specific red and yellow actuators are designed for high-contrast mechanical visibility. Always check if the actuator is translucent; if it is solid, it relies on the "I/O" markings rather than an internal light to show status.
� Can I use this for a 3-wire system?
Yes. In a 4-pin DPST setup, you typically run the hot (live) wire through one pair of pins and the neutral wire through the other. This ensures that when the switch is "OFF," the entire machine is electrically "cold," preventing any risk of shock even if the plug is incorrectly polarized.
