Product FAQs
5 answersWhat types of enclosures or panels is the 140U-I6C3-C15-M compatible with?
This 3-pole breaker is designed for integration into industrial control panels and motor control centers. It is a unit-mount device that bolts directly to the chassis or backplate.
What wire sizes are compatible with the terminals on the 140U-I6C3-C15-M?
The factory-installed lugs accept wire gauges from 14 AWG up to 4 AWG. Ensure you torque the terminals to the manufacturer specifications when terminating the conductors.
Does the 140U-I6C3-C15-M allow for field-adjustable trip settings?
No, this thermal-magnetic breaker features fixed thermal and fixed magnetic trip elements. Both the long-time and instantaneous (LI) trip functions are factory-set and cannot be adjusted.
Can the 140U-I6C3-C15-M be applied in DC control circuits?
Yes, in addition to its AC ratings, this breaker is rated for up to 250VDC with a 22kA interrupting capacity. This makes it suitable for various industrial DC applications.
What are the primary safety requirements when installing the 140U-I6C3-C15-M?
Always disconnect and lock out all power sources feeding the motor control center or panel before installation. Verify the circuit is fully de-energized with a calibrated multimeter to prevent arc flash or shock hazards.
