CLB-253-11ANN-W-A Equivalent & Substitute Parts

Part Overview

The CLB-253-11ANN-W-A is a thermal circuit breaker manufactured by Carling Technologies, rated for 25A at 250V AC and 32V DC with push-to-reset actuation and panel mount configuration. This component is classified as Active product status and carries multiple international approvals including CE, cUL, TUV, UL1077, and UL1500 certifications. The device is ROHS3 compliant and REACH unaffected.

Substitute parts are identified when equivalent electrical and mechanical parameters align with the main component specifications, enabling direct functional replacement in circuit protection applications where thermal breaker technology is required.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the CLB-253-11ANN-W-A are identified from the OptiFuse CBW57 series based on the following critical parameters:

Matching Parameters:

• Current Rating: 25A
• Voltage Rating - AC: 250V
• Actuator Type: Push to Reset
• Mounting Type: Panel Mount
• Number of Poles: 1
• Breaker Type: Thermal
• Illumination: None

Parameter Variance:

• Voltage Rating - DC: Substitute parts are rated 50V DC, exceeding the main part specification of 32V DC. This represents an uprated capability suitable for applications requiring higher DC voltage tolerance.

All substitute parts maintain Active product status and ROHS3 compliance. Substitute parts carry approval agencies including cURus, IP 40, SAE J1171, UL 1077, and UL 1500, providing equivalent or enhanced regulatory coverage.

Parameter Comparison

Engineering Selection Recommendations

All identified substitute parts from the OptiFuse CBW57 series maintain functional equivalence to the CLB-253-11ANN-W-A across critical electrical parameters: 25A current rating, 250V AC voltage rating, push-to-reset actuation, single-pole configuration, and panel mount design.

The substitute parts carry Active product status, ensuring ongoing manufacturer support and availability. All substitute parts are ROHS3 compliant, matching the environmental compliance profile of the main part.

Regulatory approvals for substitute parts include cURus, IP 40, SAE J1171, UL 1077, and UL 1500. The main part carries CE, cUL, TUV, UL1077, and UL1500 certifications. Both the main part and substitute parts include UL1077 and UL1500 approvals, providing common regulatory foundation for circuit breaker applications.

The DC voltage rating differential (32V main part versus 50V substitute parts) represents an uprated specification in the substitute components. This higher DC rating does not restrict substitution in applications designed for the 32V DC specification, as the substitute parts accommodate the lower voltage requirement within their rated envelope.

Inventory availability across substitute parts ranges from 764 to 1681 pieces, providing multiple sourcing options for procurement planning.

Frequently Asked Questions (FAQ)

Q: Can CBW57 series parts directly replace the CLB-253-11ANN-W-A?

A: Yes. The CBW57 series parts listed maintain identical electrical specifications for current rating (25A), AC voltage rating (250V), actuator type (push to reset), mounting configuration (panel mount), and pole count (1). All components are thermal breakers with no illumination, meeting the functional requirements for direct substitution.

Q: What is the significance of the higher DC voltage rating in substitute parts?

A: Substitute parts are rated 50V DC compared to the main part's 32V DC rating. This represents an uprated capability. In applications where the circuit operates at 32V DC or lower, the substitute parts function within their rated specification and provide equivalent protection. The higher rating does not create incompatibility with lower voltage applications.

Q: Are there differences in regulatory approvals between the main part and substitutes?

A: Both the main part and substitute parts carry UL1077 and UL1500 approvals. The main part includes CE, cUL, and TUV certifications. Substitute parts include cURus, IP 40, and SAE J1171 approvals. The common UL certifications provide regulatory alignment for standard circuit breaker applications. Application-specific regulatory requirements should be verified against the complete approval list for each part.

Q: Do all substitute parts have identical part number suffixes?

A: No. The CBW57 series includes variants with different suffixes (EJ, ES, ES-5H, PB-5X, PS, PS-5X, PS-5XD). These suffixes indicate manufacturing or packaging variations within the series. All listed variants maintain the same electrical specifications and are functionally equivalent for the stated application parameters.

Q: What is the inventory status for substitute parts?

A: All substitute parts are listed as New Original In Stock with quantities ranging from 764 to 1681 pieces. CBW57-PS-25A maintains the highest inventory at 1681 pieces, while CBW57-PB-25A-5X maintains 764 pieces. Inventory levels support procurement planning for both immediate and planned requirements.

Q: Are substitute parts ROHS3 compliant?

A: Yes. All substitute parts from the OptiFuse CBW57 series are ROHS3 compliant, matching the environmental compliance status of the main CLB-253-11ANN-W-A component.
