CLB-063-27ENN-W-D Equivalent & Substitute Parts

Part Overview

The CLB-063-27ENN-W-D is a thermal circuit breaker manufactured by Carling Technologies, rated for 6A at 250V AC and 32V DC. This single-pole, panel-mount device features push-to-reset actuation and is designed for overcurrent protection in low-voltage applications. The part maintains active product status with full compliance to CE, cUL, TUV, UL1077, and UL1500 standards. Substitute parts are identified to provide alternative sourcing options when the primary part is unavailable or when inventory requirements necessitate component alternatives with equivalent electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitute parts for the CLB-063-27ENN-W-D are qualified based on the following electrical and mechanical parameters:

Matching Parameters:

Current Rating: 6A
Voltage Rating - AC: 250V
Breaker Type: Thermal
Mounting Type: Panel Mount
Actuator Type: Push to Reset
Number of Poles: 1
RoHS Compliance: ROHS3 Compliant

Voltage Rating - DC Consideration: The substitute parts (CBW57 series) are rated for 50V DC, which exceeds the 32V DC specification of the main part. This represents an uprated DC voltage capability and does not restrict substitution in applications operating at or below 32V DC.

All substitute parts are manufactured by OptiFuse and belong to the CBW57 series. Each substitute maintains thermal breaker functionality with identical AC voltage rating, current rating, and panel-mount configuration.

Engineering Selection Recommendations

All three substitute parts (CBW57-EJ-6A, CBW57-EL4-6A, and CBW57-ES-6A) are functionally equivalent to the CLB-063-27ENN-W-D for applications requiring 6A thermal circuit protection at 250V AC and 32V DC or lower.

Compliance Alignment: The CLB-063-27ENN-W-D carries approvals from CE, cUL, TUV, UL1077, and UL1500. The CBW57 series substitutes carry approvals from cURus, IP 40, SAE J1171, UL 1077, and UL 1500. Both product lines maintain UL 1077 and UL 1500 certification, confirming thermal circuit breaker compliance standards.

Inventory Availability: CBW57-ES-6A offers the highest inventory level at 2,884 pieces, followed by CBW57-EL4-6A at 1,393 pieces and CBW57-EJ-6A at 1,366 pieces. The main part CLB-063-27ENN-W-D maintains 1,039 pieces in stock.

DC Voltage Rating: The substitute parts are rated for 50V DC, exceeding the 32V DC requirement. This uprated specification does not restrict use in applications operating within the 32V DC specification of the main part.

Frequently Asked Questions (FAQ)

Q: Can CBW57-EJ-6A, CBW57-EL4-6A, or CBW57-ES-6A be used as direct replacements for CLB-063-27ENN-W-D?

A: Yes. All three substitute parts match the critical electrical parameters: 6A current rating, 250V AC voltage rating, thermal breaker type, push-to-reset actuation, single-pole configuration, and panel-mount design. The 50V DC rating of the substitutes exceeds the 32V DC specification and does not restrict substitution in applications operating at or below 32V DC.

Q: What is the difference between CBW57-EJ-6A, CBW57-EL4-6A, and CBW57-ES-6A?

A: All three parts share identical electrical and mechanical specifications. The designations (EJ, EL4, ES) represent different actuator or terminal configurations within the CBW57 series. Selection among these three should be based on specific terminal or actuator requirements for your application and available inventory.

Q: Are the substitute parts RoHS and REACH compliant?

A: Yes. All substitute parts (CBW57-EJ-6A, CBW57-EL4-6A, CBW57-ES-6A) are ROHS3 compliant and REACH unaffected, matching the compliance status of the CLB-063-27ENN-W-D.

Q: What certifications do the substitute parts carry?

A: The CBW57 series carries cURus, IP 40, SAE J1171, UL 1077, and UL 1500 approvals. The main part carries CE, cUL, TUV, UL1077, and UL1500 approvals. Both product lines maintain UL 1077 and UL 1500 thermal circuit breaker certifications.

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

A: No. The 50V DC rating of the CBW57 series substitutes represents an uprated specification compared to the 32V DC rating of the CLB-063-27ENN-W-D. This does not restrict substitution in applications operating at or below 32V DC.

Q: What is the Moisture Sensitivity Level (MSL) of the substitute parts?

A: All CBW57 series substitutes carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.
