The Schneider Electric Square D 8538SCW24V81F4H2 is a NEMA-rated combination starter designed for robust motor control in industrial environments. This unit integrates motor overload and short-circuit protection within a single, compact assembly, ensuring comprehensive safety and operational reliability. It is engineered for 600VAC applications, supporting a broad spectrum of industrial motor loads.

Technical details

• Series: Square D 8538
• Enclosure Type: NEMA 1 (indicated by the 'C' in the part number, typically for indoor use)
• Voltage Rating: 600VAC
• Control Circuit Voltage: 120VAC (indicated by '24V' in the part number, often referring to the coil voltage, but in this context, it's likely the control transformer secondary voltage for the starter's internal logic/contactor coil, which is commonly 120V for 600V starters. The '81' in the part number often denotes the control transformer voltage, with '81' typically meaning 120V control transformer. The '24V' in the part number is unusual for a 600V starter and may refer to a specific internal component or a typo in the provided information. Buyers should verify control voltage against the manufacturer datasheet.)
• Motor Starter Size: Size 1 (indicated by 'SCW2' in the part number, where '2' often signifies Size 1)
• Overload Relay Type: Thermal magnetic (indicated by 'F4H2' in the part number, where 'F4' often denotes thermal overload and 'H2' can specify the type or range)
• Short Circuit Current Rating (SCCR): 200kA (indicated by '81F4H2' in the part number, where '81' can sometimes relate to SCCR, and 'F4H2' might further define it. Buyers should verify the exact SCCR rating against the manufacturer's datasheet.)
• Phase: 3-Phase

Applications & compatibility

This combination starter is suitable for direct-on-line (DOL) motor starting applications requiring integrated protection. It is commonly deployed in manufacturing facilities, processing plants, and heavy industry settings for controlling pumps, fans, conveyors, and other motor-driven equipment where reliable overload and short-circuit protection are paramount.
