• Voltage Rating: This coil is engineered for a 440V AC supply, a common voltage in many industrial and commercial applications.
• Frequency Compatibility: Designed to function optimally at both 50Hz and 60Hz, providing flexibility for use in different regions.
• Broad Compatibility: Specifically designed to fit and function perfectly with a comprehensive list of Siemens contactor series, including:
  • 3TF30-33
  • 3TF40-43
  • 3TH3
  • 3TH4
  • 3TB40…44
  • 3TC44
  • 3TH8
• Direct Replacement: This product is the official replacement for the discontinued Siemens 3TY4803-0AR1, guaranteeing a perfect fit and identical performance specifications.

Benefit

• Guaranteed Reliability: As a genuine Siemens component, the 3TY7403-0AR2 ensures long-lasting performance and consistent operation of your contactors, minimizing downtime and maintenance costs.
