GS2-B0-24-450-1B-CG Circuit Breaker Equivalent & Substitute Parts

Part Overview

The GS2-B0-24-450-1B-CG is an active-status circuit breaker manufactured by Carling Technologies, designed for DIN rail mounting applications. This magnetic (hydraulic delay) breaker operates at 5A current rating with dual voltage capability: 240V AC and 125V DC. The lever-actuated, 2-pole configuration provides protection in industrial and commercial electrical systems. Substitute parts are identified to support procurement flexibility, inventory management, and supply chain continuity when the primary part becomes unavailable or when alternative sourcing is required.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the GS2-B0-24-450-1B-CG are identified based on strict parametric equivalence across the following critical specifications:

Mandatory Matching Parameters:

• Mounting Type: DIN Rail
• Breaker Type: Magnetic (Hydraulic Delay)
• Current Rating: 5A
• Voltage Rating - AC: 240V
• Voltage Rating - DC: 125V
• Actuator Type: Lever
• Number of Poles: 2
• Illumination: None

The substitute part 7940102677 (Weidmüller QY-2-13-DM-U2-05-B1 125 VDC) meets all mandatory electrical and mechanical parameters, confirming functional and physical compatibility for direct substitution in applications requiring the GS2-B0-24-450-1B-CG specifications.

Parameter Comparison

Engineering Selection Recommendations

Primary Part: GS2-B0-24-450-1B-CG (Carling Technologies)

The Carling Technologies GS2-B0-24-450-1B-CG maintains active product status with UL489 and CCC approval certifications. This part is suitable for applications requiring established Carling Technologies supply relationships and UL489-specific compliance documentation.

Substitute Part: 7940102677 (Weidmüller QY-2-13-DM-U2-05-B1 125 VDC)

The Weidmüller 7940102677 provides parametric equivalence with expanded certification coverage, including CE, CSA C22.2 No 235, UL1077, and VDE approvals. This substitute is suitable for applications requiring multi-regional compliance documentation or when Weidmüller supply chain availability is preferred. Both parts maintain active product status and REACH/RoHS compliance.

Selection between these parts depends on certification requirements specific to the end application and regional regulatory frameworks, not on electrical or mechanical performance differences.

Frequently Asked Questions (FAQ)

Q: Can the Weidmüller 7940102677 directly replace the Carling GS2-B0-24-450-1B-CG in existing installations?

A: Yes. Both parts are parametrically equivalent across all critical specifications: 5A current rating, 240V AC / 125V DC voltage ratings, 2-pole lever-actuated magnetic (hydraulic delay) breaker configuration, and DIN rail mounting. Physical and electrical compatibility is confirmed.

Q: What are the key differences between these two parts?

A: The parts are electrically and mechanically identical. Differences exist only in manufacturer identity, series designation (G versus QY), and approval certifications. The Weidmüller part carries additional certifications (CE, CSA C22.2 No 235, UL1077, VDE) compared to the Carling part (UL489, CCC).

Q: Are both parts RoHS and REACH compliant?

A: Yes. The Carling GS2-B0-24-450-1B-CG is ROHS3 Compliant and REACH Unaffected. The Weidmüller 7940102677 is RoHS Compliant and REACH Unaffected. Both meet environmental regulatory requirements.

Q: Which part should be selected for a new design?

A: Selection depends on the target market and required certifications. For UL489-specific applications, the Carling part is appropriate. For applications requiring CE, CSA, UL1077, or VDE compliance, the Weidmüller part is appropriate. Both are active products with confirmed inventory availability.

Q: Are there any packaging or inventory considerations?

A: Both parts are supplied in bulk packaging. The Carling GS2-B0-24-450-1B-CG has 900 pieces in stock. The Weidmüller 7940102677 has 1092 pieces in stock. Packaging format is identical for both.

Q: Can these parts be used interchangeably in mixed installations?

A: Yes. Since both parts meet identical electrical and mechanical specifications, they can be used in the same circuit or system without functional impact. However, documentation and traceability records should reflect the specific manufacturer and part number used in each installation location.
