CLB-153-11ANN-R-A Circuit Breaker Equivalent & Substitute Parts
Part Overview
The CLB-153-11ANN-R-A is a thermal circuit breaker manufactured by Carling Technologies, rated for 15A at 250V AC and 32V DC with push-to-reset panel mount actuation. This single-pole breaker is designed for overcurrent protection in AC and DC applications and maintains Active product status with full compliance to CE, cUL, TUV, UL1077, and UL1500 standards.
Substitute parts are necessary when the primary part experiences extended lead times, inventory constraints, or when design flexibility permits selection from qualified alternative manufacturers. OptiFuse CBW57 series thermal circuit breakers provide equivalent electrical and mechanical functionality across multiple part configurations.

Substitute Part Grouping Explanation
Substitution of the CLB-153-11ANN-R-A is determined by strict equivalence across the following critical parameters:
Mandatory Matching Parameters:
- Current Rating: 15A
- Voltage Rating - AC: 250V
- Mounting Type: Panel Mount
- Breaker Type: Thermal
- Actuator Type: Push to Reset
- Number of Poles: 1
- Illumination: None
- RoHS Compliance: ROHS3 Compliant
Allowable Variation:
- Voltage Rating - DC: The main part specifies 32V DC. Substitute parts rated at 50V DC are acceptable as this represents a higher voltage capability and maintains backward compatibility with 32V DC applications.
All substitute parts are from the OptiFuse CBW57 series and satisfy these equivalence criteria. Differences in part number suffixes (such as -EJ, -EL4, -ES, -GS, -HB, -HS, -PB) reflect internal design variations, connector types, or packaging configurations that do not affect electrical performance or mechanical compatibility in the specified application parameters.

Engineering Selection Recommendations
All listed OptiFuse CBW57 series circuit breakers are qualified substitutes for the CLB-153-11ANN-R-A based on electrical and mechanical parameter equivalence. Selection among the substitute options should be based on the following factors:
Compliance and Certifications: The CLB-153-11ANN-R-A carries approvals from CE, cUL, TUV, UL1077, and UL1500. All OptiFuse CBW57 substitutes carry cURus, IP 40, SAE J1171, UL 1077, and UL 1500 certifications. Both part families meet UL 1077 and UL 1500 standards, ensuring compatibility in regulated applications.
Product Status: All substitute parts maintain Active product status, confirming ongoing manufacturer support and availability.
Inventory Availability: OptiFuse CBW57-HB-15A-P offers the highest inventory level at 8,822 pieces, followed by CBW57-ES-15A at 3,521 pieces. The original CLB-153-11ANN-R-A maintains 875 pieces in stock.
Voltage Capability: OptiFuse substitutes are rated at 50V DC compared to the original 32V DC rating. This higher DC voltage rating provides enhanced capability for DC applications while maintaining full compatibility with 32V DC circuits.
Moisture Sensitivity: OptiFuse CBW57 parts specify Moisture Sensitivity Level (MSL) 1 (Unlimited), indicating no moisture-related handling restrictions during storage or assembly.
Frequently Asked Questions (FAQ)
Q: Can OptiFuse CBW57 series breakers directly replace the Carling CLB-153-11ANN-R-A?
A: Yes. All listed OptiFuse CBW57 part numbers are direct substitutes. They match the mandatory electrical parameters (15A, 250V AC, 32V DC compatible), mechanical configuration (panel mount, push-to-reset, single-pole), and compliance standards (UL 1077, UL 1500).
Q: What is the significance of the different CBW57 part number suffixes?
A: The suffixes (-EJ, -EL4, -ES, -GS, -HB, -HS, -PB, and their variants with -5X or -WX) indicate internal design variations, connector types, or packaging configurations. These differences do not affect electrical performance or mechanical compatibility for the specified application parameters.
Q: Why do OptiFuse substitutes have a higher DC voltage rating (50V vs. 32V)?
A: The 50V DC rating on OptiFuse parts represents a higher voltage capability. This is acceptable for substitution because it maintains backward compatibility with 32V DC applications. A component rated for higher voltage can safely operate at lower voltages.
Q: Are there any compliance differences between the original and substitute parts?
A: Both the original CLB-153-11ANN-R-A and all OptiFuse CBW57 substitutes comply with UL 1077 and UL 1500 standards. The original carries additional CE and TUV approvals, while OptiFuse parts carry cURus and SAE J1171 certifications. Application requirements determine which certifications are necessary.
Q: Which OptiFuse substitute should be selected if multiple options are available?
A: Selection should prioritize inventory availability and application-specific connector or packaging requirements indicated by the part number suffix. CBW57-HB-15A-P offers the highest inventory level. Consult application documentation for any specific connector or mounting requirements that may be indicated by the suffix designation.
Q: Is there any difference in thermal performance between the original and substitute parts?
A: All parts are classified as thermal circuit breakers with identical current ratings (15A). Thermal performance characteristics are determined by the 15A rating specification, which is identical across all parts listed.
Q: Can these parts be used interchangeably in existing designs?
A: Yes, provided the application does not require specific certifications beyond UL 1077 and UL 1500. Panel mount configuration and push-to-reset actuation are identical. Verify connector type compatibility based on the part number suffix if the design specifies a particular connector interface.
