CMB-153-11ANN-B-D Equivalent & Substitute Parts

Part Overview

The CMB-153-11ANN-B-D is a thermal circuit breaker manufactured by Carling Technologies, designed for panel mount applications. This single-pole breaker operates at 15A with 250V AC and 32V DC ratings, featuring push-to-reset actuation and no illumination. 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 qualified alternatives that meet identical electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitution eligibility for thermal circuit breakers is determined by strict equivalence across electrical and mechanical parameters. The CMB-153-11ANN-B-D establishes the baseline specification: 15A current rating, 250V AC voltage rating, 32V DC voltage rating, single-pole configuration, push-to-reset actuation, and panel mount form factor.

All substitute parts listed maintain these core parameters. OptiFuse CBW57 series alternatives satisfy the electrical requirements with identical current and AC voltage ratings. The DC voltage rating for substitute parts is specified at 50V, which exceeds the 32V requirement of the main part and therefore remains compatible for applications operating within the 32V DC envelope.

Substitution logic is based exclusively on:

Current Rating (Amps): 15A
Voltage Rating - AC: 250V
Voltage Rating - DC: 32V minimum (50V acceptable as higher rating)
Mounting Type: Panel Mount
Breaker Type: Thermal
Actuator Type: Push to Reset
Number of Poles: 1
RoHS Compliance: ROHS3 Compliant

Engineering Selection Recommendations

All listed substitute parts maintain Active product status and ROHS3 compliance, ensuring long-term availability and environmental regulatory adherence. The OptiFuse CBW57 series alternatives carry regulatory approvals including cURus, IP 40, SAE J1171, UL 1077, and UL 1500 certifications, providing cross-certification compatibility with the original Carling Technologies part.

The primary distinction among substitute options lies in packaging and inventory availability. CBW57-HB-15A-P offers the highest current inventory at 8,822 pieces, followed by CBW57-ES-15A with 3,521 pieces. These alternatives are suitable for direct substitution in applications where the 32V DC operating envelope is maintained and panel mount configuration is required.

Selection between substitute parts should be based on procurement lead time requirements, packaging preferences, and inventory availability rather than electrical performance, as all alternatives satisfy the specified electrical and mechanical parameters.

Frequently Asked Questions (FAQ)

Q: Can OptiFuse CBW57 series parts directly replace the CMB-153-11ANN-B-D?

A: Yes. All listed OptiFuse CBW57 alternatives meet the electrical specifications of the CMB-153-11ANN-B-D. The 15A current rating, 250V AC voltage rating, push-to-reset actuation, single-pole configuration, and panel mount form factor are identical across all parts. The 50V DC rating of substitute parts exceeds the 32V DC requirement and remains compatible.

Q: What is the significance of the different part number suffixes in the CBW57 series?

A: The suffixes (EJ, EL4, ES, GS, HB, HS, PB, etc.) represent different packaging configurations, connector types, or terminal styles within the CBW57 thermal circuit breaker platform. All variants maintain identical electrical performance at 15A, 250V AC, and 50V DC ratings.

Q: Are there inventory considerations when selecting a substitute?

A: Yes. Inventory levels vary significantly across the substitute options. CBW57-HB-15A-P maintains the highest stock at 8,822 pieces, while CBW57-PB-15A has the lowest at 827 pieces. Procurement timelines may be influenced by current inventory availability.

Q: Do all substitute parts carry the same regulatory certifications?

A: All substitute parts carry cURus, UL 1077, and UL 1500 certifications. The original CMB-153-11ANN-B-D carries CE, cUL, TUV, UL1077, and UL1500 certifications. Both sets of certifications satisfy industrial thermal circuit breaker standards.

Q: Is the higher DC voltage rating of substitute parts a concern?

A: No. A higher DC voltage rating (50V versus 32V) indicates greater electrical capability and does not create compatibility issues when operating within the 32V DC envelope. The component remains suitable for the application.

Q: What packaging options are available?

A: All parts listed are supplied in Bulk packaging. Specific terminal or connector configurations are indicated by the part number suffixes but do not affect electrical substitution eligibility.
