BR3C50AC Equivalent & Substitute Parts

Part Overview

The BR3C50AC is a 3-pole branch circuit breaker with C-curve characteristics and 50A current rating, manufactured by Weidmüller. This product is classified as obsolete, making identification of functionally equivalent alternatives essential for system maintenance and component procurement. The BR3C50AC serves as a thermal-magnetic protection device for AC/DC applications and requires substitution with active product lines that maintain electrical and mechanical compatibility.

Substitute Part Grouping Explanation

The BR3C50AC has been superseded by the 2478510000 model from Weidmüller's MCB 489 series. Substitution is based on the following critical parameters that ensure functional equivalence:

• Current Rating: 50A (maintained across both models)
• Pole Configuration: 3-pole (maintained across both models)
• Breaker Type: Thermal Magnetic protection mechanism
• Voltage Rating - AC: 240 V AC/DC operation
• Actuator Type: Lever-operated manual control
• Mounting Standard: DIN Rail compatibility
• Regulatory Compliance: Both models carry equivalent international certifications (CE, CSA, TUV, UL489, VDE)

The 2478510000 represents the active product continuation with identical electrical performance characteristics and mechanical form factor.

Engineering Selection Recommendations

The 2478510000 (MCB 489 series) is the direct equivalent for BR3C50AC replacement. Selection is based on:

• Product Status Alignment: The substitute is an active product, ensuring ongoing availability and support, whereas the BR3C50AC is obsolete.
• Regulatory Compliance: Both components share identical ECCN (EAR99) and HTSUS classifications, confirming equivalent trade and export status.
• Certification Parity: The 2478510000 carries all major international approvals (CE, CSA C22.2 No 5, CSA C22.2 No 235, TUV, UL489, VDE), meeting or exceeding the compliance profile of the original part.
• Electrical Specifications: Identical 50A current rating, 3-pole configuration, and thermal-magnetic protection mechanism ensure drop-in compatibility in existing circuit protection applications.

Frequently Asked Questions (FAQ)

Q: Can the 2478510000 be used as a direct replacement for BR3C50AC in existing installations?

A: Yes. Both components share identical current ratings (50A), pole configuration (3-pole), breaker type (thermal-magnetic), and regulatory classifications. The 2478510000 is the active product continuation of the BR3C50AC line.

Q: What is the primary reason for substitution?

A: The BR3C50AC is classified as obsolete. The 2478510000 provides equivalent functionality with active product status, ensuring continued availability and manufacturer support.
