CLB-153-12CNN-B-A/15 Circuit Breaker Equivalent & Substitute Parts
Part Overview
The CLB-153-12CNN-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. The product maintains active 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 alternative manufacturers meeting identical electrical and mechanical specifications. The CLB-153-12CNN-B-A/15 has documented equivalents within the OptiFuse CBW57 series that maintain functional parity across critical parameters.

Substitute Part Grouping Explanation
Substitution eligibility for the CLB-153-12CNN-B-A/15 is determined by strict equivalence across the following parameters:
Critical Matching Parameters:
- Current Rating: 15A (exact match required)
- Voltage Rating - AC: 250V (exact match required)
- Breaker Type: Thermal (exact match required)
- Mounting Type: Panel Mount (exact match required)
- Actuator Type: Push to Reset (exact match required)
- Number of Poles: 1 (exact match required)
Acceptable Variance:
- Voltage Rating - DC: The CLB-153-12CNN-B-A/15 specifies 32V DC. All substitute parts in the CBW57 series are rated for 50V DC, which represents a higher voltage capability and is therefore acceptable for applications requiring 32V DC operation.
All substitute parts listed are manufactured by OptiFuse and belong to the CBW57 series. Each substitute maintains thermal breaker functionality, single-pole configuration, push-to-reset operation, and panel mount installation. All substitutes carry ROHS3 compliance and active product status.

Engineering Selection Recommendations
All listed substitute parts meet the functional and compliance requirements of the CLB-153-12CNN-B-A/15. Selection among the CBW57 series alternatives should be based on the following factors:
Compliance Certifications: The CLB-153-12CNN-B-A/15 carries CE, cUL, TUV, UL1077, and UL1500 approvals. All OptiFuse CBW57 substitutes carry cURus, IP 40, SAE J1171, UL 1077, and UL 1500 certifications. Both product lines maintain regulatory compliance for industrial circuit protection applications.
Inventory Availability: CBW57-HB-15A-P offers the highest inventory level at 8,822 pieces. CBW57-ES-15A provides 3,521 pieces. CBW57-HS-15A-5X and CBW57-PB-15A-5X each provide approximately 1,800 pieces. Selection based on availability supports supply chain continuity.
Moisture Sensitivity Level (MSL): Most CBW57 variants specify MSL 1 (Unlimited), indicating no moisture sensitivity constraints during storage and handling. This aligns with standard industrial circuit breaker requirements.
REACH and Environmental Compliance: All substitute parts maintain ROHS3 compliance. REACH status is documented as REACH Unaffected for applicable variants, confirming environmental regulatory alignment.
Frequently Asked Questions (FAQ)
Q: Can CBW57 series breakers directly replace the CLB-153-12CNN-B-A/15 in existing panel installations?
A: Yes. All CBW57 substitutes maintain identical panel mount mechanical interfaces, push-to-reset actuation, and single-pole configuration. Electrical specifications for 15A at 250V AC are matched exactly. The higher 50V DC rating of CBW57 parts does not prevent operation in 32V DC applications.
Q: What is the significance of the different CBW57 part number suffixes (EJ, EL4, ES, GS, HB, HS, PB, PS)?
A: The suffixes denote internal design variants and connector configurations within the CBW57 series. All variants listed maintain identical electrical ratings and thermal protection characteristics. Suffix differences reflect manufacturing options and do not affect functional substitution capability for the CLB-153-12CNN-B-A/15 application.
Q: Are there any thermal or trip-time differences between the CLB-153-12CNN-B-A/15 and CBW57 substitutes?
A: The provided specifications confirm both product lines are thermal breakers with identical current ratings and voltage specifications. Thermal response characteristics are determined by the 15A rating and thermal mechanism design, which are equivalent across all listed parts.
Q: Which CBW57 variant should be selected for highest availability?
A: CBW57-HB-15A-P maintains the largest inventory at 8,822 pieces. This variant is suitable for applications requiring immediate availability or bulk procurement.
Q: Do all CBW57 substitutes carry the same regulatory approvals as the CLB-153-12CNN-B-A/15?
A: Both product lines carry UL 1077 and UL 1500 certifications. The CLB-153-12CNN-B-A/15 includes additional CE and TUV approvals. CBW57 variants carry cURus and SAE J1171 certifications. For applications requiring specific regional certifications, verify that the selected substitute meets all applicable regulatory requirements for the intended market.
Q: Is the 50V DC rating of CBW57 parts compatible with 32V DC applications?
A: Yes. A higher voltage rating indicates greater electrical stress capability. A 50V DC rated breaker operates safely in 32V DC circuits. The breaker will not be overstressed and will provide equivalent protection.
Q: What is the ECCN classification for these circuit breakers?
A: Both the CLB-153-12CNN-B-A/15 and all CBW57 substitutes are classified as EAR99, indicating they are not subject to export control restrictions under the Export Administration Regulations.
