BR1C2AC Circuit Breaker - Equivalent & Substitute Parts

Part Overview

The BR1C2AC is a single-pole branch circuit breaker manufactured by Weidmüller, designed for AC/DC applications with a 2A current rating. This component is classified as obsolete, making identification of suitable substitute parts essential for ongoing system maintenance and component procurement.

The necessity to identify equivalent parts stems from the product's obsolete status, which may result in limited availability through standard distribution channels. Substitute parts must maintain functional equivalence across critical electrical and mechanical parameters to ensure proper system operation.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the BR1C2AC is based on the following critical parameters that must align between the main part and substitute candidates:

• Manufacturer: Weidmüller (same manufacturer ensures design compatibility)
• Number of Poles: 1 (single-pole configuration)
• Current Rating: 2A (identical amperage requirement)
• Product Type: Circuit Breaker with AC/DC capability
• Breaker Characteristic: C Curve thermal magnetic operation
• Mounting Interface: DIN Rail compatibility
• Regulatory Compliance: CE, CSA, TUV, UL489, VDE certifications

The substitute part 2477830000 (MCB 489 1P C 2A ACDC) meets these criteria as a functionally equivalent alternative from the same manufacturer within the active product portfolio.

Parameter Comparison

Engineering Selection Recommendations

The substitute part 2477830000 is classified as active product status, ensuring ongoing availability and manufacturer support. Both the main part and substitute share identical ECCN (EAR99) and HTSUS classifications, confirming regulatory alignment for export and tariff purposes.

The substitute part carries CE, CSA C22.2 No 5, CSA C22.2 No 235, TUV, UL489, and VDE approvals, providing comprehensive compliance coverage for industrial applications. The RoHS Compliant status of the substitute part meets current environmental regulations.

Selection of the substitute part 2477830000 is supported by matching current rating (2A), single-pole configuration, and identical moisture sensitivity classification. The active product status of the substitute ensures long-term procurement viability compared to the obsolete main part.

Frequently Asked Questions (FAQ)

Q: What makes 2477830000 a suitable substitute for BR1C2AC?

A: Both parts are single-pole, 2A circuit breakers from Weidmüller with identical moisture sensitivity levels and regulatory classifications (ECCN, HTSUS). The substitute is an active product within the MCB 489 series, providing functional equivalence with enhanced availability.

Q: Are there mechanical compatibility concerns when substituting BR1C2AC with 2477830000?

A: Both parts are designed for DIN Rail mounting. Physical dimensions and mounting interfaces are consistent with Weidmüller's standard single-pole breaker form factor, supporting direct mechanical replacement in existing installations.

Q: Does the substitute part maintain the same electrical performance characteristics?

A: Both parts operate as single-pole circuit breakers with 2A current ratings. The substitute specifies 277 V AC and 60 V DC voltage ratings, providing the electrical performance envelope required for the application.

Q: What is the significance of the product status difference?

A: The main part BR1C2AC is obsolete, indicating discontinued manufacturing. The substitute 2477830000 maintains active product status, ensuring continued availability, technical support, and compliance with current manufacturing standards.

Q: Are certifications equivalent between the two parts?

A: Both parts share EAR99 ECCN and 8536.20.0020 HTSUS classifications. The substitute carries comprehensive industrial certifications (CE, CSA, TUV, UL489, VDE), meeting or exceeding the compliance requirements of the obsolete main part.
