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

Part Overview

The CLB-083-11ANN-B-A 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-A has five parametric equivalents within the OptiFuse CBW57 series, all maintaining the same current rating, voltage ratings, and mounting configuration.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CLB-083-11ANN-B-A is determined by strict equivalence across the following parameters:

Critical Matching Parameters:

• Current Rating: 8A (exact match required)
• Voltage Rating - AC: 250V (exact match required)
• Breaker Type: Thermal (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)
• Illumination: None (exact match required)

Allowable Variance:

• Voltage Rating - DC: The main part specifies 32V DC. All substitute parts are rated for 50V DC, which represents a higher voltage capability and is functionally compatible in applications requiring 32V DC operation.

All five substitute parts (CBW57-PS-8A-5X, CBW57-EJ-8A, CBW57-HS-8A, CBW57-AS-8A, CBW57-PB-8A-5X) are manufactured by OptiFuse and belong to the CBW57 series. Each maintains Active product status and ROHS3 compliance.

Parameter Comparison

Engineering Selection Recommendations

All five OptiFuse CBW57 series substitutes maintain Active product status and full ROHS3 compliance, ensuring long-term availability and environmental regulatory adherence equivalent to the primary CLB-083-11ANN-B-A part.

Certification Alignment: The CLB-083-11ANN-B-A carries CE, cUL, TUV, UL1077, and UL1500 approvals. The OptiFuse substitutes carry cURus, IP 40, SAE J1171, UL 1077, and UL 1500 certifications. Both part families meet UL 1077 and UL 1500 standards for thermal circuit breaker performance and safety.

Inventory Availability: CBW57-HS-8A offers the highest current inventory at 3,442 pieces. CBW57-PB-8A-5X and CBW57-PS-8A-5X provide intermediate availability at 1,332 and 1,096 pieces respectively. CBW57-EJ-8A and CBW57-AS-8A maintain 1,027 and 1,145 pieces in stock.

DC Voltage Rating Consideration: All substitute parts are rated for 50V DC, exceeding the 32V DC requirement of the primary part. This higher rating provides additional design margin in DC applications without compromising performance in the specified 32V DC operating range.

Frequently Asked Questions (FAQ)

Q: Can CBW57 series breakers directly replace the CLB-083-11ANN-B-A in existing panel designs?

A: Yes. All five CBW57 variants share identical current rating (8A), AC voltage rating (250V), thermal breaker type, panel mount configuration, push-to-reset actuation, and single-pole design. Physical mounting compatibility is maintained across all substitutes.

Q: What is the significance of the higher 50V DC rating on OptiFuse substitutes compared to the 32V DC rating of the Carling part?

A: The 50V DC rating on CBW57 parts represents a higher voltage capability specification. In applications operating at 32V DC, the 50V DC rated breaker functions identically to the 32V DC rated part while providing additional voltage margin. No performance difference occurs within the 32V DC operating range.

Q: Are there differences between the five CBW57 substitute part numbers?

A: The five part numbers (CBW57-PS-8A-5X, CBW57-EJ-8A, CBW57-HS-8A, CBW57-AS-8A, CBW57-PB-8A-5X) represent different package configurations or connector variants within the CBW57 series. All maintain identical electrical specifications: 8A current rating, 250V AC, 50V DC, thermal operation, panel mount, and push-to-reset actuation.

Q: Do certification differences between Carling and OptiFuse parts affect substitution eligibility?

A: Both manufacturers' parts meet UL 1077 and UL 1500 standards for thermal circuit breaker safety and performance. The Carling part includes CE and TUV certifications; OptiFuse parts include cURus and SAE J1171 certifications. Application-specific regulatory requirements determine whether certification differences impact selection.

Q: What is the Moisture Sensitivity Level (MSL) rating on OptiFuse parts?

A: All CBW57 substitutes carry MSL 1 (Unlimited), indicating no moisture sensitivity constraints during storage or handling. This specification applies to component packaging and does not affect operational performance.

Q: Can I mix Carling CLB-083-11ANN-B-A and OptiFuse CBW57 breakers in the same equipment?

A: Yes. All parts share identical electrical and mechanical specifications for the critical parameters governing circuit breaker function. Mixed sourcing is permissible from an engineering compatibility standpoint, though design documentation should reflect the specific part numbers used.
