SI-LM40KVD Equivalent & Substitute Parts

Part Overview

The SI-LM40KVD is a non-locking interlock switch manufactured by Banner Engineering Corporation, classified as a DPST (Double Pole Single Throw) switch with NO/NC (Normally Open/Normally Closed) configuration. This component is designed for panel disconnect applications with screw terminal connections and IP65 ingress protection rating.

The SI-LM40KVD carries an obsolete product status. Identifying equivalent substitute parts is necessary to maintain system functionality, ensure supply chain continuity, and support ongoing maintenance and replacement requirements for installations currently utilizing this component.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SI-LM40KVD is determined by strict alignment of the following critical parameters:

Electrical Compatibility Requirements:

• Circuit configuration must be DPST-NO/NC
• Current rating must support minimum 10A (AC) and 6A (DC)
• Voltage rating must support 110VAC and 24VDC operation

Mechanical & Environmental Compatibility Requirements:

• Actuator type must be Panel Disconnect
• Termination style must be Screw Terminal
• Operating temperature range must encompass -30°C ~ 80°C
• Ingress protection rating must be IP65 or higher
• Approval agencies must include CE, CSA, and UL certifications

Regulatory & Compliance Requirements:

• RoHS3 compliance mandatory
• REACH Unaffected status required

The SI-LS83SRAD meets all substitution criteria and is classified as an active product, providing a viable replacement for the obsolete SI-LM40KVD.

Parameter Comparison

Engineering Selection Recommendations

The SI-LS83SRAD is qualified as a direct substitute for the SI-LM40KVD based on electrical and functional equivalence. Both components share identical circuit configuration, current ratings, voltage ratings, operating temperature range, ingress protection classification, and regulatory certifications (CE, CSA, UL).

The primary mechanical difference is the conduit thread size: the SI-LM40KVD features M20 threading while the SI-LS83SRAD features M16 threading. This difference requires mechanical evaluation during installation to ensure proper panel mounting and conduit connection compatibility with existing system infrastructure.

The SI-LS83SRAD carries active product status, ensuring ongoing availability and manufacturer support, whereas the SI-LM40KVD is obsolete. Selection of the SI-LS83SRAD provides long-term supply chain security and compliance with current manufacturing standards.

Frequently Asked Questions (FAQ)

Q: Can the SI-LS83SRAD directly replace the SI-LM40KVD in existing installations?

A: Electrical and functional replacement is direct. The conduit thread size difference (M20 vs. M16) requires mechanical assessment of the mounting interface. If the existing panel or conduit connection is designed for M20 threading, mechanical adaptation may be necessary.

Q: Are the electrical specifications identical between these two parts?

A: Yes. Both components support 10A (AC) and 6A (DC) current ratings, 110VAC and 24VDC voltage operation, DPST-NO/NC circuit configuration, and identical operating temperature range (-30°C ~ 80°C).

Q: What is the significance of the product status difference?

A: The SI-LM40KVD is obsolete, indicating discontinued manufacturing and limited future availability. The SI-LS83SRAD is active, ensuring continued production, technical support, and supply chain reliability for future replacement needs.

Q: Do both parts meet the same regulatory and compliance standards?

A: Yes. Both components are CE, CSA, and UL certified, ROHS3 compliant, and REACH unaffected, meeting identical regulatory requirements.

Q: What packaging difference exists between these parts?

A: The SI-LM40KVD is supplied with standard packaging, while the SI-LS83SRAD is supplied in bulk packaging. Bulk packaging may affect order quantities and handling procedures.
