CMB-153-11CNN-R-A Equivalent & Substitute Parts
Part Overview
The CMB-153-11CNN-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 holds active product status with full compliance to CE, cUL, TUV, UL1077, and UL1500 standards.
Substitute parts are necessary when the original manufacturer part becomes unavailable, when inventory constraints require alternative sourcing, or when equivalent performance specifications from alternative manufacturers meet application requirements. All substitute parts listed maintain identical electrical ratings and mechanical compatibility with the original specification.

Engineering Selection Recommendations
All listed substitute parts maintain active product status and full compliance with international safety standards. The CBW57 series from OptiFuse carries UL 1077 and UL 1500 certifications, which align with the original part's UL approval requirements. The substitute parts also include cURus certification and SAE J1171 compliance, providing additional regulatory coverage for automotive and industrial applications.
The DC voltage rating differential (50V on substitutes versus 32V on the original) represents an enhancement rather than a limitation, as the substitute parts maintain full compatibility with the original 32V DC specification while providing additional margin for DC circuit protection.
All substitute parts are manufactured to ROHS3 compliance and maintain REACH unaffected status, ensuring environmental and regulatory alignment with the original specification. Inventory availability across the CBW57 series ranges from 827 to 8822 pieces, providing multiple sourcing options for production requirements.
Frequently Asked Questions (FAQ)
Q: Can CBW57 series parts directly replace the CMB-153-11CNN-R-A in existing applications?
A: Yes. All CBW57 substitute parts maintain identical current rating (15A), AC voltage rating (250V), breaker type (thermal), mounting configuration (panel mount), actuation mechanism (push to reset), and pole count (1). Panel mount dimensions and electrical performance are equivalent, enabling direct substitution in existing circuit designs.
Q: What is the significance of the higher DC voltage rating on substitute parts?
A: The CBW57 series is rated for 50V DC compared to the original 32V DC specification. This higher rating provides additional protection margin for DC applications and does not create incompatibility with 32V DC circuits. The substitute parts operate safely at or below the original 32V DC specification.
Q: Are all CBW57 variants listed electrically identical?
A: Yes. All listed CBW57 part numbers (EJ, EL4, ES, ES-5X, GS-WB, HB-P, HS-5X, PB, PB-5X, PB-WX) share identical electrical specifications: 15A current rating, 250V AC, 50V DC, thermal breaker type, push-to-reset actuation, and single-pole configuration. Suffix designations indicate packaging, connector, or terminal variations that do not affect electrical performance.
Q: What certifications do substitute parts carry?
A: All CBW57 substitute parts carry cURus, IP 40, SAE J1171, UL 1077, and UL 1500 certifications. These certifications provide coverage for industrial, automotive, and consumer applications and align with the original part's UL1077 and UL1500 approvals.
Q: Is there a difference in RoHS or REACH compliance between the original and substitute parts?
A: No. Both the original CMB-153-11CNN-R-A and all CBW57 substitute parts are ROHS3 compliant and REACH unaffected, ensuring equivalent environmental and regulatory status.
Q: Which CBW57 variant should be selected if inventory is a primary concern?
A: The CBW57-HB-15A-P variant carries the highest inventory level at 8822 pieces, followed by CBW57-ES-15A at 3521 pieces. Both parts maintain identical electrical specifications and certifications as all other variants in the series.
Q: Are there any mechanical compatibility considerations when substituting parts?
A: All substitute parts are panel mount thermal circuit breakers with push-to-reset actuation and single-pole configuration, matching the original part's mechanical interface. Panel cutout dimensions and mounting hardware compatibility are equivalent across all listed variants.
