Key Parameters

Substitute Part Grouping Explanation

Substitution of the CLB-183-11ANN-B-A is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Current Rating: 18A
• Voltage Rating - AC: 250V
• Mounting Type: Panel Mount
• Breaker Type: Thermal
• Actuator Type: Push to Reset
• Number of Poles: 1

Allowable Variation Parameters:

• Voltage Rating - DC: The substitute part may exceed the DC voltage rating of the original component, provided the minimum requirement of 32V DC is met or exceeded.

The CBW57-HS-18A from OptiFuse meets all mandatory matching parameters and exceeds the DC voltage specification (50V DC versus 32V DC), making it a valid parametric equivalent.

Parameter Comparison

Engineering Selection Recommendations

Both the CLB-183-11ANN-B-A and CBW57-HS-18A are Active status products with full regulatory compliance. The CLB-183-11ANN-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. Both components are ROHS3 compliant and REACH unaffected.

Selection between these parts is based on availability and certification requirements specific to the application. The CBW57-HS-18A provides enhanced DC voltage capability (50V versus 32V), which offers additional operational margin in DC applications. Both components are suitable for direct substitution in 18A, 250V AC panel mount thermal circuit breaker applications.

Frequently Asked Questions (FAQ)

Q: Can the CBW57-HS-18A replace the CLB-183-11ANN-B-A in all applications?

A: The CBW57-HS-18A is a parametric equivalent for applications requiring 18A thermal protection at 250V AC and up to 32V DC. The higher DC voltage rating (50V) of the substitute part does not restrict its use in lower voltage applications.

Q: What are the key differences between these two circuit breakers?

A: The primary difference is the DC voltage rating: CLB-183-11ANN-B-A is rated to 32V DC, while CBW57-HS-18A is rated to 50V DC. All other electrical and mechanical parameters are identical. Certification bodies differ slightly between manufacturers.

Q: Are both parts available in the same packaging?

A: Both parts are supplied in Bulk packaging. Inventory availability differs: CLB-183-11ANN-B-A has 893 pieces in stock, while CBW57-HS-18A has 1215 pieces in stock.

Q: Do these circuit breakers have illumination options?

A: Neither the CLB-183-11ANN-B-A nor the CBW57-HS-18A includes illumination features.

Q: What certifications apply to both parts?

A: Both components meet UL 1077 and UL 1500 standards. The CLB-183-11ANN-B-A additionally carries CE and TUV certifications, while the CBW57-HS-18A carries cURus, IP 40, and SAE J1171 certifications.
