SI-LM40KHD Equivalent & Substitute Parts

Part Overview

The SI-LM40KHD is a non-locking interlock switch manufactured by Banner Engineering Corporation, classified as a DPST (Double Pole Single Throw) switch with dual NO/NC (Normally Open/Normally Closed) circuits. This component is designed for panel disconnect applications with screw terminal connections and M20 conduit threading.

The SI-LM40KHD is currently listed as obsolete. Identifying equivalent and substitute parts is necessary to maintain system functionality and ensure continued availability for maintenance, repair, and new installations where this component specification is required.

Key Parameters

Substitute Part Grouping Explanation

The SI-LS83SRAD qualifies as a substitute for the SI-LM40KHD based on the following critical parameters that determine functional interchangeability:

Matching Parameters:

• Circuit configuration: DPST-NO/NC
• Current ratings: 10A (AC), 6A (DC)
• Voltage ratings: 110VAC, 24VDC
• Actuator type: Panel Disconnect
• Termination style: Screw Terminal
• Operating temperature range: -30°C to 80°C
• Ingress protection: IP65 (Dust Tight, Water Resistant)
• Approval agencies: CE, CSA, UL
• RoHS and REACH compliance: ROHS3 Compliant, REACH Unaffected

Differing Parameter:

• Conduit thread size: SI-LM40KHD uses M20; SI-LS83SRAD uses M16

The SI-LS83SRAD maintains electrical and environmental specifications identical to the SI-LM40KHD. The conduit thread size difference (M20 versus M16) represents a mechanical variation that must be evaluated within the specific installation context.

Parameter Comparison

Engineering Selection Recommendations

The SI-LS83SRAD is an active product from Banner Engineering Corporation that maintains full electrical and environmental compliance with the SI-LM40KHD specification. Both components carry identical certifications (CE, CSA, UL) and meet ROHS3 and REACH compliance requirements.

The primary consideration for component selection is the conduit thread size difference: the SI-LM40KHD specifies M20 threading, while the SI-LS83SRAD specifies M16 threading. This mechanical difference requires evaluation based on the installation's conduit connection requirements and panel mounting configuration.

The SI-LS83SRAD's active product status provides advantages in terms of ongoing availability and supply chain continuity compared to the obsolete SI-LM40KHD.

Frequently Asked Questions (FAQ)

Q: Can the SI-LS83SRAD directly replace the SI-LM40KHD in all applications?

A: The SI-LS83SRAD matches all electrical specifications, current ratings, voltage ratings, and environmental protection requirements of the SI-LM40KHD. The conduit thread size difference (M20 versus M16) must be evaluated for compatibility with the specific installation's conduit connection interface.

Q: What is the significance of the conduit thread size difference?

A: The SI-LM40KHD uses M20 conduit threading, while the SI-LS83SRAD uses M16 conduit threading. This affects the physical connection to the conduit entry point on the installation panel or enclosure. Compatibility depends on whether the installation accommodates M16 threading or requires M20 threading specifically.

Q: Are both components certified for the same regulatory standards?

A: Yes. Both the SI-LM40KHD and SI-LS83SRAD carry identical approval certifications: CE, CSA, and UL. Both are ROHS3 Compliant and REACH Unaffected.

Q: What is the difference in product status between these components?

A: The SI-LM40KHD is classified as obsolete, indicating it is no longer in active production. The SI-LS83SRAD is classified as active, meaning it is currently manufactured and available through standard supply channels.

Q: Do both components have identical electrical performance specifications?

A: Yes. Both components are rated for 10A AC and 6A DC current, 110VAC and 24VDC voltage, operate across the same temperature range (-30°C to 80°C), and provide identical IP65 ingress protection with DPST-NO/NC circuit configuration.
