Technical details

• Series: Square D 8539SBT
• Type: Combination Motor Starter
• Configuration: Includes a thermal magnetic circuit breaker and a magnetic motor starter.
• Voltage Rating: The part number '43' in 8539SBT43V07 typically indicates a 480V or 600V class rating. Verify against manufacturer datasheet for precise voltage.
• Enclosure Type: The 'V07' suffix often denotes a NEMA Type 1 or Type 12 enclosure, suitable for indoor general-purpose use or protection against dust and falling dirt. Verify against manufacturer datasheet for precise enclosure rating.
• Control Circuit Voltage: The 'V07' may also indicate the control circuit voltage. Verify against manufacturer datasheet for precise control voltage.
• Motor Full Load Amps (FLA) Rating: The part number encodes the maximum FLA the starter can protect and control. The '43' in 8539SBT43V07 suggests a specific FLA range. Consult the manufacturer's datasheet for the exact FLA rating.
• Interrupting Capacity: Combination starters are rated for a specific short-circuit current interrupting capacity (SCCR) to safely interrupt fault currents. Verify the SCCR rating against the manufacturer's datasheet.
