Technical details

• Series: Square D 8539SCT
• Type: Non-Reversing Combination Motor Starter
• Configuration: Includes a motor starter and a disconnect mechanism (circuit breaker or fuse holder). Specific disconnect type (e.g., circuit breaker or fuse type) should be verified against the full manufacturer datasheet.
• Voltage Rating: The '42' in the part number typically indicates a 480VAC voltage class. Please verify with the manufacturer's datasheet for precise voltage specifications.
• Enclosure Type: The 'V07' in the part number often denotes an open-style device or a specific enclosure type. Refer to the manufacturer's documentation for definitive enclosure details.
• Control Circuit Voltage: The 'V07' may also relate to the control circuit voltage. Confirm this specification with the manufacturer's datasheet.
• Overload Relay: Features an adjustable thermal overload relay for motor protection against sustained overcurrents.
• Interrupting Capacity: The integrated disconnect provides a specified interrupting capacity to safely clear fault currents. This value is critical for system safety and should be confirmed from the manufacturer's specifications.
