Application-Specific FAQ
Q: Can the CK95BE300 be used for reversing duty?
A: Yes, with two CK95BE300 units wired in a reversing configuration with mechanical and electrical interlocking. Consult GE application notes for wiring diagrams.
Q: What overload relay is compatible with this contactor?
A: GE THLC series thermal overload relays are designed to mount directly onto the CK95 series. Select the relay current range to match your motor’s full-load amperage.
Q: Is this contactor suitable for capacitor bank switching (AC-6b)?
A: The CK95BE300 is rated AC-3/AC-4. For capacitor switching (AC-6b), please consult GE’s derating tables or specify a dedicated capacitor contactor.
Q: What is the electrical life expectancy?
A: At AC-3 duty, GE CK95 series contactors are rated for millions of operating cycles. Actual life depends on load, switching frequency, and maintenance intervals.
Q: Can I get a datasheet or wiring diagram?
A: Yes. Contact support@konmask.com and reference part number CK95BE300 to receive the official GE technical datasheet.
