SI-LM40KVE Equivalent & Substitute Parts

Part Overview

The SI-LM40KVE is a non-locking interlock switch manufactured by Banner Engineering Corporation, classified as a DPST (Double Pole Single Throw) circuit device. This panel disconnect actuator is designed for industrial control applications requiring dual-channel switching with 10A AC and 6A DC current capacity at 110VAC and 24VDC respectively. The product is currently obsolete, necessitating identification of functionally equivalent alternatives for ongoing maintenance and new installations where this model is no longer available.

Key Parameters

Substitute Part Grouping Explanation

The SI-LS83SRAE qualifies as a functional substitute for the SI-LM40KVE based on the following critical parameters:

Matching Electrical Specifications:

• Circuit configuration: DPST-NC
• Current rating: 10A (AC), 6A (DC)
• Voltage rating: 110VAC, 24VDC
• Operating temperature range: -30°C ~ 80°C
• Ingress protection: IP65 - Dust Tight, Water Resistant

Matching Mechanical & Functional Characteristics:

• Actuator type: Panel Disconnect
• Termination style: Screw Terminal
• Non-locking operation
• Regulatory compliance: CE, CSA, UL certifications
• RoHS3 compliance and REACH unaffected status

Substitution Basis: The SI-LS83SRAE maintains electrical equivalence across all load conditions and environmental specifications. The primary difference is the conduit thread size (M16 versus M20), which represents a mechanical interface variation that must be evaluated during installation planning. The substitute part is currently active in production, ensuring long-term availability compared to the obsolete SI-LM40KVE.

Parameter Comparison

Engineering Selection Recommendations

The SI-LS83SRAE is the appropriate substitute for the SI-LM40KVE in applications requiring equivalent electrical and environmental performance. Both components maintain identical current and voltage ratings, circuit configuration, and regulatory certifications (CE, CSA, UL). The substitute part's active production status ensures supply chain continuity and technical support availability.

The conduit thread size difference (M16 versus M20) requires mechanical interface assessment during installation. This variation may necessitate adapter fittings or panel modifications depending on existing conduit infrastructure. All other mechanical and electrical parameters remain functionally equivalent, supporting direct functional replacement in control circuits.

Both components maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment for new equipment designs and legacy system upgrades.

Frequently Asked Questions (FAQ)

Q: Can the SI-LS83SRAE directly replace the SI-LM40KVE without modification?

A: Electrical and functional replacement is direct. The conduit thread size difference (M16 versus M20) requires mechanical interface evaluation. Existing M20 conduit connections may require adapter fittings for the M16 threaded connection on the substitute part.

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

A: Yes. Both components provide 10A AC and 6A DC current capacity at 110VAC and 24VDC voltage ratings with DPST-NC circuit configuration.

Q: What is the primary reason for substitution?

A: The SI-LM40KVE is obsolete. The SI-LS83SRAE is an active production equivalent that maintains all critical electrical specifications and regulatory certifications while ensuring ongoing availability.

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

A: Yes. Both components are rated IP65 for ingress protection, operate across -30°C to 80°C temperature range, and carry CE, CSA, and UL certifications. Both are ROHS3 compliant and REACH unaffected.

Q: What packaging differences exist between these parts?

A: The SI-LM40KVE is supplied in standard packaging, while the SI-LS83SRAE is supplied in bulk packaging. This distinction affects order quantities and handling procedures but does not impact component functionality.

Q: Are there any holding force specifications that differ?

A: The SI-LM40KVE specifies 2kgf holding force. The SI-LS83SRAE does not provide a holding force specification in available documentation. This parameter should be confirmed with Banner Engineering Corporation if holding force is a critical application requirement.
