Description
🔹 Product Introduction
The Siemens 3AY1715-6L, designation VS30041, is a replacement vacuum interrupter used in compatible Siemens 3AH4 vacuum circuit breakers. Siemens’ official product catalog lists this part for the 3AH4305-2, 3AH4305-4, and 3AH4305-6 circuit-breaker variants. It is a medium-voltage switchgear component designed to interrupt electrical current within a sealed vacuum chamber during switching and fault-clearing operations.
The vacuum interrupter is intended for electrical power distribution systems, industrial substations, and switchgear maintenance applications. Correct selection is essential for safe operation and reliable circuit interruption.
Buyer Compatibility Questions
- Q1: Is 3AY1715-6L compatible with my circuit breaker? Check the complete breaker model, such as 3AH4305-2/4/6, and verify the equipment serial number and original interrupter designation.
- Q2: Can I replace VS30041 with another vacuum interrupter? Only if Siemens documentation confirms the replacement part is suitable for the exact breaker configuration.
- Q3: What should I provide before ordering? Supply the circuit-breaker nameplate, serial number, existing interrupter part number, and clear photographs of the installed assembly.
- Q4: Does the part require adjustment after installation? Installation, contact alignment, travel, and contact pressure must follow the applicable Siemens service instructions and be completed by qualified switchgear personnel.
- Q5: Is the product new or used? Confirm the actual item’s condition, testing documentation, and warranty with the seller before purchase.
