Cutler Hammer, Eaton circuit breaker features a UVR mechanism with pigtail leads for extra protection. The circuit breaker has a voltage rating of 60 v.
What is the primary function of the UVH5LP23K accessory?
It is an undervoltage release (UVR) mechanism that automatically trips the circuit breaker when the control voltage drops below a safe threshold, protecting downstream equipment from low-voltage conditions.
Which circuit breaker frames are compatible with this undervoltage release?
This UVR is designed for use with Eaton Cutler-Hammer Series C molded case circuit breakers, specifically N-Frame models.
Where is the UVH5LP23K installed on the circuit breaker?
This undervoltage release mechanism is installed in the left pole cavity of the breaker. The breaker cover must be removed for field installation.
How is this undervoltage release wired into the control circuit?
The mechanism comes equipped with factory-installed pigtail leads, allowing for direct splicing into your control wiring system.
What is the exact control voltage range for this UVR mechanism?
While listed with a 60V rating, this direct current (DC) undervoltage release operates reliably within a 48 to 60 Vdc control voltage range.
How is the breaker reset after an undervoltage trip?
Once the control voltage is restored to the required 48 to 60 Vdc range, the circuit breaker handle must be manually toggled to the OFF position and then to the ON position to restore power.
Are there alternate part numbers used to identify this Eaton UVR?
Yes, this undervoltage release is also identified by the alternate part number 1494D43G32 and UPC 786679027257.
