Siemens 3AY1715-6L (VS30041) – OEM Replacement Spare for Industrial Control Assemblies

The Siemens 3AY1715-6L (VS30041) is an original Siemens spare part code that’s typically used as a dedicated replacement piece within Siemens control gear and switchgear assemblies. From my experience, parts in the 3A* family are designed for precise fit and compatibility, so maintenance teams don’t have to rework panels or improvise. If you’re maintaining critical panels or medium/low-voltage switchgear, this kind of OEM-coded spare keeps downtime low and documentation clean.

You might notice that Siemens assigns both a primary order number and an internal code (here, 3AY1715-6L and VS30041). That dual reference is handy for traceability—especially when cross-checking older BOMs or regional spare lists. In many cases, this part drops in without adjustments, which is exactly what maintenance teams want at 2 a.m.

Application Fields

This part is typically specified for maintenance of Siemens control cabinets and switchgear where exact replacement is required:

• Factory automation panels and MCCs
• Power distribution and protection cabinets
• Process industries (chemicals, water, F&B) where uptime is critical
• Critical infrastructure maintenance (utilities, transport, data centers)

A maintenance engineer from a packaging plant told us, “We swapped the coded spare during our Saturday window—no drilling, no wiring changes—and were back online in under 30 minutes.” That’s the kind of small win that adds up over a year.

Advantages & Value

• Reliability: Genuine Siemens component quality and consistent fit seem to reduce post-maintenance callbacks.
• Compatibility: Matches the intended host device, avoiding the trial-and-error of third-party substitutes.
• Cost Control: Shorter downtime and fewer rework hours typically offset the premium of OEM parts.
• Technical Support: Clear part coding simplifies technical queries and document retrieval.

Suggested Supporting Components

To streamline installation, teams often prepare related items:

• Siemens OEM mounting hardware or clip kits for the host assembly
• Replacement labels/markers for panel documentation updates
• Compatible fasteners and panel screws (stainless or zinc-plated, as per cabinet spec)
• Protective gaskets or covers used in the original build standard

Installation & Maintenance

• Environment: Install inside a clean, dry control cabinet with adequate ventilation; follow the host device’s enclosure/IP rating.
• Safety: Isolate power, lockout/tagout, and discharge stored energy before work; use ESD precautions if the surrounding assembly includes sensitive electronics.
• Procedure: Reference the Siemens service manual for removal/fit steps and torque values. Avoid improvised modifications.
• Routine checks: Periodically verify mounting integrity and absence of vibration-induced loosening; document part change in the cabinet log.

Quality & Certifications

As an OEM spare intended for Siemens assemblies, compliance typically follows the host device. In many cases you can expect:

• CE conformity aligned with the complete assembly
• RoHS-compliant materials for most current Siemens parts
• UL/CSA recognition at the assembly level where applicable

Warranty: 12 months (365 days) from delivery under normal use, backed by our stated replacement/return terms above.
