CLB-083-11ANN-B-F Circuit Breaker Equivalent & Substitute Parts

Part Overview

The CLB-083-11ANN-B-F is a thermal circuit breaker manufactured by Carling Technologies, rated for 8A 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 and maintains Active product 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 alternative manufacturers meeting identical electrical and mechanical specifications. The CLB-083-11ANN-B-F has five parametric equivalents within the OptiFuse CBW57 series, all maintaining the same current rating, voltage ratings, and functional characteristics.

Substitute Part Grouping Explanation

All five substitute parts (CBW57-PS-8A-5X, CBW57-EJ-8A, CBW57-HS-8A, CBW57-AS-8A, CBW57-PB-8A-5X) are classified as parametric equivalents to the CLB-083-11ANN-B-F based on the following substitution criteria:

Matching Parameters:

• Current Rating: 8A
• Voltage Rating - AC: 250V
• Mounting Type: Panel Mount
• Breaker Type: Thermal
• Actuator Type: Push to Reset
• Number of Poles: 1
• Illumination: None
• RoHS Compliance: ROHS3 Compliant

Variance Parameter:

• Voltage Rating - DC: Substitute parts are rated for 50V DC versus the main part's 32V DC rating. The higher DC voltage rating of substitute parts provides equivalent or superior performance in applications requiring 32V DC operation.

All substitute parts are manufactured by OptiFuse and belong to the CBW57 series. Each maintains Active product status and carries equivalent regulatory approvals (cURus, UL 1077, UL 1500) suitable for the same application environments.

Parameter Comparison

Engineering Selection Recommendations

All five OptiFuse CBW57 series substitutes are suitable for direct replacement of the CLB-083-11ANN-B-F in applications operating at 8A, 250V AC, and 32V DC or lower. Selection among the five substitute options should be based on:

Regulatory Compliance: All substitutes carry cURus and UL 1077/UL 1500 certifications, meeting the same safety standards as the original part. The main part additionally carries CE and TUV approvals; however, the substitute parts maintain equivalent functional safety through their UL certifications.

Availability: Inventory levels vary across the substitute options. CBW57-HS-8A maintains the highest stock level at 3,442 pieces, followed by CBW57-PB-8A-5X at 1,332 pieces, CBW57-AS-8A at 1,145 pieces, CBW57-EJ-8A at 1,027 pieces, and CBW57-PS-8A-5X at 1,096 pieces.

DC Voltage Rating: The substitute parts are rated for 50V DC, which exceeds the 32V DC requirement of the main part. This higher rating provides operational margin in DC applications and does not create incompatibility with 32V DC circuits.

Moisture Sensitivity: All OptiFuse substitutes carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity constraints during storage or handling.

Frequently Asked Questions (FAQ)

Q: Can CBW57 series parts directly replace the CLB-083-11ANN-B-F?

A: Yes. All five CBW57 variants (CBW57-PS-8A-5X, CBW57-EJ-8A, CBW57-HS-8A, CBW57-AS-8A, CBW57-PB-8A-5X) are parametric equivalents with matching current ratings (8A), AC voltage ratings (250V), mounting type (panel mount), actuator type (push to reset), and pole configuration (single pole). The 50V DC rating of substitutes exceeds the 32V DC requirement and presents no compatibility issues.

Q: What is the difference between the five substitute part numbers?

A: The five substitute parts are all members of the OptiFuse CBW57 series with identical electrical specifications. The differences in part numbers (PS-8A-5X, EJ-8A, HS-8A, AS-8A, PB-8A-5X) reflect variations in connector or terminal configurations, packaging designations, or internal manufacturing variants. All maintain the same thermal breaker function, current rating, and voltage ratings.

Q: Are there any compliance differences between the main part and substitutes?

A: The CLB-083-11ANN-B-F carries CE, cUL, TUV, UL1077, and UL1500 approvals. The OptiFuse substitutes carry cURus, IP 40, SAE J1171, UL 1077, and UL 1500 approvals. Both sets of certifications confirm suitability for the same safety-critical applications. The substitutes do not carry CE or TUV markings but maintain equivalent UL certification coverage.

Q: Why do the substitute parts have a higher DC voltage rating (50V vs. 32V)?

A: The 50V DC rating of OptiFuse CBW57 parts represents the maximum voltage the breaker can safely interrupt in DC circuits. A higher rating does not affect performance in lower-voltage applications. Circuits operating at 32V DC or below function identically with either the 32V-rated or 50V-rated breaker.

Q: Which substitute part should be selected for new designs?

A: Selection should prioritize availability and connector configuration requirements. CBW57-HS-8A offers the highest inventory level (3,442 pieces). All five substitutes are functionally equivalent and carry Active product status, making any suitable for new design implementation.

Q: Are the substitute parts RoHS compliant?

A: Yes. All five OptiFuse CBW57 substitutes are ROHS3 compliant, matching the RoHS compliance status of the CLB-083-11ANN-B-F.
