Part Overview
The CLB-153-11ANN-B-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 holds Active product status with full compliance to CE, cUL, TUV, UL1077, and UL1500 standards.
Substitute parts become necessary when the primary part experiences extended lead times, inventory constraints, or when design flexibility permits selection from qualified alternatives that meet identical electrical and mechanical specifications. The substitute parts listed below are parametric equivalents manufactured by OptiFuse, all belonging to the CBW57 series.

Substitute Part Grouping Explanation
Substitution eligibility for the CLB-153-11ANN-B-A is determined by strict alignment of the following critical parameters:
Mandatory Matching Parameters:
- Current Rating: 15A
- Voltage Rating - AC: 250V
- Mounting Type: Panel Mount
- Actuator Type: Push to Reset
- Number of Poles: 1
- Breaker Type: Thermal
- Illumination: None
Allowable Variance:
- Voltage Rating - DC: The CLB-153-11ANN-B-A operates at 32V DC. All listed substitute parts from OptiFuse operate at 50V DC, which represents a higher voltage capability and is therefore compatible for applications requiring 32V DC operation.

Engineering Selection Recommendations
All listed substitute parts meet the electrical and mechanical requirements for direct replacement of the CLB-153-11ANN-B-A. Selection among the OptiFuse CBW57 series alternatives should be based on the following factors:
Regulatory Compliance: All substitute parts maintain ROHS3 compliance and REACH Unaffected status, consistent with the primary part. OptiFuse parts carry cURus, IP 40, SAE J1171, UL 1077, and UL 1500 certifications, providing equivalent regulatory coverage to the Carling Technologies CLB series.
Product Status: All substitute parts maintain Active product status, ensuring continued availability and manufacturer support.
Inventory Availability: OptiFuse CBW57 series parts demonstrate robust inventory levels across all variants, with CBW57-HB-15A-P offering the highest stock position at 8,822 pieces.
Voltage Capability: The 50V DC rating of all OptiFuse substitutes exceeds the 32V DC requirement of the primary part, providing enhanced voltage margin for DC applications without compromising AC performance at 250V.
Moisture Sensitivity: OptiFuse parts specify MSL 1 (Unlimited) where documented, indicating superior moisture handling characteristics compared to unspecified MSL ratings.
Frequently Asked Questions (FAQ)
Q: Can OptiFuse CBW57 series breakers directly replace the Carling Technologies CLB-153-11ANN-B-A?
A: Yes. All listed OptiFuse CBW57 variants are parametric equivalents matching the critical specifications: 15A current rating, 250V AC voltage rating, panel mount configuration, push-to-reset actuation, single-pole design, and thermal breaker type. The 50V DC rating of OptiFuse parts exceeds the 32V DC requirement and is compatible with 32V DC applications.
Q: What is the significance of the different part number suffixes in the CBW57 series (EJ, EL4, ES, GS, HB, HS, PB, PS)?
A: The suffixes denote internal design variations within the CBW57 series. All variants listed maintain identical electrical ratings and mechanical specifications relevant to substitution. Suffix variations reflect manufacturing options, connector types, or internal component configurations that do not affect functional equivalence for the specified 15A, 250V AC, 32V DC application.
Q: Are there any mechanical mounting differences between the CLB-153-11ANN-B-A and CBW57 substitutes?
A: No. Both the primary part and all substitute parts are specified as panel mount with push-to-reset actuation and single-pole configuration. Mechanical compatibility is assured for direct panel mounting applications.
Q: What certifications apply to the OptiFuse CBW57 substitutes?
A: OptiFuse CBW57 parts carry cURus, IP 40, SAE J1171, UL 1077, and UL 1500 certifications. These certifications provide equivalent regulatory coverage to the Carling Technologies CLB series certifications (CE, cUL, TUV, UL1077, UL1500) for thermal circuit breaker applications.
Q: Why do OptiFuse CBW57 parts have a higher DC voltage rating (50V) than the primary part (32V)?
A: The 50V DC rating represents the maximum voltage capability of the OptiFuse design. This higher rating is compatible with 32V DC applications and provides additional voltage margin. Higher voltage capability does not compromise performance at lower voltage levels.
Q: Is RoHS3 compliance maintained across all substitute options?
A: Yes. All listed OptiFuse CBW57 variants maintain ROHS3 compliance and REACH Unaffected status, matching the regulatory posture of the CLB-153-11ANN-B-A.
Q: Which OptiFuse CBW57 variant offers the best inventory availability?
A: CBW57-HB-15A-P provides the highest inventory level at 8,822 pieces in stock. CBW57-ES-15A follows with 3,521 pieces. All variants maintain sufficient inventory for production requirements.
