CLB-063-12CNN-W-F Equivalent & Substitute Parts

Part Overview

The CLB-063-12CNN-W-F is a thermal circuit breaker manufactured by Carling Technologies, rated for 6A at 250V AC and 32V DC with push-to-reset panel mount actuation. This single-pole breaker is designed for overcurrent protection in low-voltage DC and AC 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 ratings and mechanical specifications align with the original design requirements, enabling component interchangeability in applications where the primary part is unavailable or inventory constraints exist.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the CLB-063-12CNN-W-F are qualified based on strict electrical and mechanical parameter alignment. The following criteria determine substitution eligibility:

Critical Matching Parameters:

• Current Rating: 6A (exact match required)
• Voltage Rating - AC: 250V (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)
• Breaker Type: Thermal (exact match required)

Allowable Variance:

• Voltage Rating - DC: The main part specifies 32V DC. Substitute parts rated at 50V DC are acceptable as this represents a higher voltage capability, maintaining backward compatibility with the original 32V DC specification.

All identified substitute parts are manufactured by OptiFuse under the CBW57 series and meet these substitution criteria. Each substitute maintains ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment with the original component.

Parameter Comparison

Engineering Selection Recommendations

All three OptiFuse CBW57 series substitutes (CBW57-EJ-6A, CBW57-EL4-6A, CBW57-ES-6A) are qualified equivalents for the CLB-063-12CNN-W-F. Selection among these substitutes is based on inventory availability and application-specific requirements:

CBW57-ES-6A offers the highest inventory availability at 2,884 pieces in stock, providing the most reliable supply for high-volume applications.

CBW57-EL4-6A maintains 1,393 pieces in stock, suitable for standard production requirements.

CBW57-EJ-6A provides 1,366 pieces in stock, available for immediate deployment.

All substitute parts carry active product status and maintain compliance with international approval agencies including cURus, UL 1077, and UL 1500 certifications. The elevated DC voltage rating of 50V on substitute parts does not restrict their use in 32V DC applications, as the higher rating ensures operational safety margins in the original circuit design.

Frequently Asked Questions (FAQ)

Q: Can CBW57 series breakers directly replace the CLB-063-12CNN-W-F in existing applications?

A: Yes. The CBW57-EJ-6A, CBW57-EL4-6A, and CBW57-ES-6A are direct electrical and mechanical equivalents. All parameters including current rating, AC voltage, mounting configuration, and actuation method are identical. The higher DC voltage rating on substitute parts (50V versus 32V) does not affect compatibility.

Q: What is the significance of the different DC voltage ratings between the main part and substitutes?

A: The main part is rated for 32V DC operation. The substitute parts are rated for 50V DC, which represents a higher voltage capability. This allows the substitutes to operate safely in the original 32V DC application with additional voltage margin.

Q: Are all three OptiFuse substitutes functionally identical?

A: Yes. CBW57-EJ-6A, CBW57-EL4-6A, and CBW57-ES-6A share identical electrical specifications and mechanical characteristics. Differences exist only in part number designation and inventory levels. Selection should be based on availability and supply chain requirements.

Q: Do the substitute parts maintain the same regulatory certifications?

A: The substitute parts carry certifications from cURus, UL 1077, and UL 1500, which overlap with the original part's approval agencies. Both the main part and substitutes are ROHS3 compliant and REACH unaffected, ensuring regulatory alignment.

Q: Is panel mount compatibility guaranteed across all parts?

A: Yes. All parts in this equivalency group are specified as panel mount with identical mechanical mounting requirements. Physical installation procedures remain unchanged during substitution.

Q: What is the thermal breaker actuation difference between parts?

A: All parts use identical push-to-reset actuation. The thermal sensing mechanism operates identically across all qualified substitutes, ensuring consistent overcurrent protection behavior.
