CLB-073-11ANN-B-A/07 Equivalent & Substitute Parts

Part Overview

The CLB-073-11ANN-B-A/07 is a single-pole thermal circuit breaker manufactured by Carling Technologies, rated for 7A at 250V AC and 32V DC. This panel-mount device features push-to-reset actuation and is designed for overcurrent protection in low-voltage applications. The part maintains active product status and carries multiple international approvals including CE, cUL, TUV, UL1077, and UL1500 certifications. Substitute parts are identified when equivalent electrical and mechanical parameters are required for component replacement or design flexibility.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the CLB-073-11ANN-B-A/07 are identified based on the following critical parameters that must align for functional equivalence:

Mandatory Matching Parameters:

• Current Rating: 7A
• Voltage Rating (AC): 250V
• Mounting Type: Panel Mount
• Breaker Type: Thermal
• Actuator Type: Push to Reset
• Number of Poles: 1

Allowable Variation:

• Voltage Rating (DC): The main part specifies 32V DC. Substitute parts rated at 50V DC are acceptable as this represents a higher voltage capability and maintains backward compatibility in applications requiring 32V DC operation.

All identified substitute parts are manufactured by OptiFuse and belong to the CBW57 series. Each substitute maintains identical AC voltage rating, current rating, mounting configuration, and actuation mechanism. The DC voltage rating increase from 32V to 50V does not restrict substitution in applications designed for the original 32V specification.

Parameter Comparison

Engineering Selection Recommendations

All four substitute parts (CBW57-EJ-7A, CBW57-EL4-7A, CBW57-ES-7A-5H, and CBW57-HS-7A-5C) maintain active product status and ROHS3 compliance, ensuring long-term availability and environmental regulatory alignment with the original CLB-073-11ANN-B-A/07.

The substitute parts carry regulatory approvals including cURus, UL 1077, and UL 1500 certifications. These certifications overlap with the original part's approval agencies, confirming compliance with applicable safety standards for thermal circuit breaker applications.

The DC voltage rating differential (50V versus 32V) in substitute parts provides enhanced voltage margin without compromising functionality in 32V DC applications. This characteristic supports component interchangeability in existing designs while offering improved performance headroom for future design iterations.

All substitute parts are available in bulk packaging with inventory levels ranging from 1,197 to 2,482 pieces, supporting both immediate replacement needs and production-scale deployments.

Frequently Asked Questions (FAQ)

Q: Can CBW57 series parts directly replace the CLB-073-11ANN-B-A/07 in existing applications?

A: Yes. The CBW57 series parts maintain identical current rating (7A), AC voltage rating (250V), mounting configuration (panel mount), actuation mechanism (push to reset), and pole count (1). These parameters define functional equivalence for thermal circuit breaker applications.

Q: What is the significance of the 50V DC rating on substitute parts versus the 32V DC rating on the original?

A: The 50V DC rating on CBW57 substitute parts represents a higher voltage capability. In applications designed for 32V DC operation, the 50V-rated substitute parts operate within their specified range and provide additional voltage margin. This does not restrict substitution.

Q: Are all substitute parts equally suitable for replacement?

A: All four substitute parts (CBW57-EJ-7A, CBW57-EL4-7A, CBW57-ES-7A-5H, CBW57-HS-7A-5C) meet the electrical and mechanical equivalence criteria. Selection among these parts may be based on inventory availability, delivery lead times, or specific application requirements not defined by the core electrical parameters.

Q: Do the substitute parts carry the same regulatory approvals as the original?

A: Substitute parts carry UL 1077 and UL 1500 certifications, which align with the original part's approval agencies. The substitute parts also carry cURus and SAE J1171 approvals, providing equivalent or enhanced regulatory coverage for thermal circuit breaker applications.

Q: What is the packaging format for substitute parts?

A: All substitute parts are supplied in bulk packaging, consistent with the original CLB-073-11ANN-B-A/07 packaging format.

Q: Are substitute parts RoHS compliant?

A: Yes. All substitute parts are ROHS3 compliant, matching the environmental compliance status of the original part.
