VLSH3S7BD Equivalent & Substitute Parts

Part Overview

The VLSH3S7BD is a black pistol grip handle with screw fixing, manufactured by Schneider Electric as part of the TeSys VLS series. This component is classified as obsolete and is no longer in active production. The handle is designed for use with TeSys VLS contactors and motor starters, providing operator interface functionality for manual control operations.

Due to its obsolete status, sourcing original VLSH3S7BD units is subject to inventory depletion. Identification of active equivalent parts ensures continuity of supply and maintains compatibility with existing TeSys VLS installations.

Engineering Selection Recommendations

For New Installations: The VLSH3S7NBD is the appropriate selection for new TeSys VLS installations. This part carries active product status and is supported by current manufacturing and supply chain infrastructure.

For Replacement and Maintenance: The VLSH3S7NBD provides direct functional equivalence to the VLSH3S7BD for replacement applications in existing TeSys VLS systems. No design modifications or reconfiguration of mounting interfaces are required.

Inventory Considerations: Both parts maintain adequate stock levels. The VLSH3S7NBD, as the active production part, provides superior long-term availability assurance compared to the obsolete VLSH3S7BD.

Compliance and Certification: Both parts share identical RoHS applicability status and environmental classifications, ensuring equivalent regulatory compliance in applications where such certifications are required.

Frequently Asked Questions (FAQ)

Q: Can the VLSH3S7NBD be used as a direct replacement for the VLSH3S7BD in existing TeSys VLS installations?

A: Yes. Both parts are identical in form factor, mounting method, and functional specification. The VLSH3S7NBD is the active production equivalent of the obsolete VLSH3S7BD and requires no modifications to existing installations.

Q: What is the primary difference between these two part numbers?

A: The VLSH3S7BD is obsolete and no longer manufactured. The VLSH3S7NBD is the current active production part with identical specifications. The substitution reflects a product line update by Schneider Electric.

Q: Are there any compatibility issues when substituting the VLSH3S7NBD for the VLSH3S7BD?

A: No compatibility issues exist. Both parts are designed for the TeSys VLS series and share identical mechanical and electrical interfaces.

Q: What does the MSL 1 (Unlimited) rating indicate?

A: MSL 1 indicates the component has unlimited shelf life and requires no special moisture control during storage or handling. This classification applies to the main part; equivalent environmental tolerance for the substitute part is supported by identical series design specifications.

Q: Should the VLSH3S7BD be preferred over the VLSH3S7NBD due to its current inventory availability?

A: No. The VLSH3S7NBD should be selected for all new applications and replacements. Although the VLSH3S7BD maintains current inventory, its obsolete status means future availability cannot be assured. The VLSH3S7NBD provides superior supply chain continuity.
