CLB-153-11ANN-B-A/15 Circuit Breaker Equivalent & Substitute Parts

Part Overview

The CLB-153-11ANN-B-A/15 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 industrial and commercial applications and maintains Active product status with full regulatory compliance including CE, cUL, TUV, UL1077, and UL1500 certifications.

Substitute parts become necessary when the primary part experiences extended lead times, inventory constraints, or when design flexibility permits selection from alternative manufacturers meeting identical electrical and mechanical specifications. The CLB-153-11ANN-B-A/15 has multiple parametric equivalents available from OptiFuse within the CBW57 series that satisfy all core functional requirements.

Substitute Part Grouping Explanation

Substitution eligibility for the CLB-153-11ANN-B-A/15 is determined by strict equivalence across the following parameters:

Critical Electrical Parameters:

Current Rating: 15A (exact match required)
Voltage Rating AC: 250V (exact match required)
Voltage Rating DC: Minimum 32V (substitute parts rated 50V DC exceed specification and remain compatible)
Breaker Type: Thermal (exact match required)

Critical Mechanical Parameters:

Actuator Type: Push to Reset (exact match required)
Mounting Type: Panel Mount (exact match required)
Number of Poles: 1 (exact match required)

Regulatory Parameters:

RoHS3 Compliance (required)
REACH Unaffected status (required)
Approval agencies: UL1077 and UL1500 certifications present in all substitutes

All OptiFuse CBW57 series parts listed below meet these criteria. The CBW57 series substitutes feature 50V DC rating, which exceeds the 32V DC requirement of the primary part and presents no compatibility limitation in applications designed for the CLB-153-11ANN-B-A/15.

Engineering Selection Recommendations

All listed OptiFuse CBW57 series substitutes are Active status products with full regulatory compliance. Selection among substitute parts should be based on the following factors:

Inventory Availability: CBW57-HB-15A-P offers the highest inventory level at 8,822 pieces, followed by CBW57-ES-15A at 3,521 pieces. These options provide superior supply chain reliability for immediate procurement needs.

Regulatory Compliance: All substitute parts carry cURus, IP 40, SAE J1171, UL 1077, and UL 1500 certifications. The primary part CLB-153-11ANN-B-A/15 carries CE, cUL, TUV, UL1077, and UL1500 certifications. Both certification sets satisfy industrial and commercial application requirements.

Voltage Rating Margin: All OptiFuse substitutes are rated for 50V DC, providing a 56% margin above the 32V DC requirement of the primary part. This enhanced rating does not create incompatibility and supports applications with higher DC voltage transients.

Moisture Sensitivity: OptiFuse CBW57 parts specify MSL 1 (Unlimited), indicating no moisture sensitivity constraints during storage or handling.

Environmental Compliance: All parts are ROHS3 Compliant and REACH Unaffected, meeting current and future regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can CBW57 series parts with 50V DC rating substitute for the CLB-153-11ANN-B-A/15 rated at 32V DC?

A: Yes. The 50V DC rating of CBW57 substitutes exceeds the 32V DC requirement of the primary part. Higher voltage ratings provide additional safety margin and do not create incompatibility in circuits designed for 32V DC operation.

Q: Are all listed OptiFuse CBW57 parts electrically identical?

A: All listed substitutes share identical electrical specifications: 15A current rating, 250V AC, 50V DC, thermal breaker type, and push-to-reset actuation. Differences in part numbers reflect manufacturing variants, connector types, or packaging configurations that do not affect core electrical function.

Q: What is the significance of the suffix codes in CBW57 part numbers (e.g., -EJ, -ES, -HB)?

A: Suffix codes identify manufacturing variants and connector/terminal configurations. These variants maintain electrical equivalence while accommodating different panel mount interfaces and wiring connection methods.

Q: Do all substitutes carry the same regulatory certifications as the CLB-153-11ANN-B-A/15?

A: All substitutes carry UL 1077 and UL 1500 certifications matching the primary part. OptiFuse parts additionally carry cURus, IP 40, and SAE J1171 certifications. The primary part carries CE and TUV certifications. Both certification profiles satisfy industrial application requirements.

Q: Is there a preferred substitute part among the listed options?

A: Selection should be based on application-specific requirements and inventory availability. CBW57-HB-15A-P and CBW57-ES-15A offer superior inventory levels for immediate availability. All other listed parts are functionally equivalent and suitable for direct substitution.

Q: What is the impact of the "-5X" suffix in part numbers like CBW57-ES-15A-5X?

A: The "-5X" suffix indicates a packaging or configuration variant. Electrical specifications remain identical to the base part number. Selection between variants should be based on specific panel mount interface requirements and connector compatibility.

Q: Are OptiFuse CBW57 parts compatible with existing CLB-153-11ANN-B-A/15 panel cutouts and mounting hardware?

A: All substitutes are panel mount thermal circuit breakers with identical mechanical form factors. Panel cutout compatibility and mounting hardware compatibility must be verified against specific panel design documentation, as these factors depend on individual equipment design rather than breaker specifications.
