Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for thermal circuit breakers is determined by strict electrical and mechanical parameter alignment. The CLB-183-27ENN-B-A establishes the baseline specification profile. The identified substitute, CBW57-HS-18A manufactured by OptiFuse, qualifies as an equivalent based on the following matching parameters:

Matching Parameters:

• Current Rating: 18A (identical)
• Voltage Rating (AC): 250 V (identical)
• Mounting Type: Panel Mount (identical)
• Actuator Type: Push to Reset (identical)
• Number of Poles: 1 (identical)
• Breaker Type: Thermal (identical)
• Product Status: Active (both parts maintained in active production)

Parameter Variance:

• Voltage Rating (DC): CLB-183-27ENN-B-A operates at 32 V DC; CBW57-HS-18A operates at 50 V DC. This variance represents an expanded DC voltage capability in the substitute part.

Parameter Comparison

Engineering Selection Recommendations

Both the CLB-183-27ENN-B-A and CBW57-HS-18A maintain active product status with unrestricted availability. Regulatory compliance is established through multiple certification agencies for each component. The CLB-183-27ENN-B-A carries CE, cUL, TUV, UL1077, and UL1500 certifications. The CBW57-HS-18A carries cURus, IP 40, SAE J1171, UL 1077, and UL 1500 certifications, with both parts achieving ROHS3 compliance and maintaining REACH unaffected status.

The primary parameter distinction between these parts is the DC voltage rating. The CBW57-HS-18A provides a higher DC rating of 50 V compared to the 32 V rating of the CLB-183-27ENN-B-A. This characteristic makes the CBW57-HS-18A suitable for applications where the original specification allows for or requires higher DC voltage tolerance.

Selection between these parts should be based on your specific application's voltage requirements and the compliance certifications required by your equipment design standards.

Frequently Asked Questions (FAQ)

Q: What defines electrical equivalence between thermal circuit breakers?

A: Electrical equivalence is established through matching current ratings, AC voltage ratings, DC voltage ratings, number of poles, and actuator type. The CLB-183-27ENN-B-A and CBW57-HS-18A are equivalent on all parameters except DC voltage rating, where the substitute provides enhanced capability.

Q: Can the CBW57-HS-18A replace the CLB-183-27ENN-B-A in all applications?

A: The CBW57-HS-18A is mechanically and electrically compatible for direct substitution when your application operates within or below the voltage specifications of the original part. The higher DC rating of the substitute does not restrict its use in lower-voltage applications.

Q: Are both parts available in the same packaging format?

A: Both parts are available in bulk packaging. The CLB-183-27ENN-B-A has 675 pieces in current inventory, while the CBW57-HS-18A has 1215 pieces in current inventory.

Q: What regulatory certifications apply to both parts?

A: Both parts hold UL 1077 and UL 1500 certifications and are ROHS3 compliant with REACH unaffected status. The CLB-183-27ENN-B-A additionally carries CE and TUV approvals, while the CBW57-HS-18A carries cURus and SAE J1171 approvals.

Q: Are there physical or mechanical differences between these parts?

A: Both parts share identical mounting configuration (panel mount), actuator mechanism (push to reset), and pole configuration (single pole). No mechanical differences exist between these components.
