Key Parameters

Substitute Part Grouping Explanation

Substitution of the BR1C30AC is determined by the following critical parameters:

• Current Rating: 30A (exact match required)
• Number of Poles: 1P (single-pole configuration)
• Breaker Characteristic: C-curve thermal-magnetic operation
• Voltage Compatibility: AC/DC rated operation
• Manufacturer: Weidmüller (same manufacturer ensures design continuity)
• Regulatory Compliance: CE, CSA, TUV, UL489, VDE certifications
• Environmental Classification: MSL 1 (Unlimited moisture sensitivity)

The substitute part 2477970000 satisfies all substitution criteria through matching current rating, pole configuration, thermal-magnetic breaker type, dual AC/DC voltage ratings, and equivalent regulatory approvals.

Parameter Comparison

Engineering Selection Recommendations

The 2477970000 is the designated substitute for BR1C30AC based on the following engineering criteria:

• Functional Equivalence: Both components are single-pole, 30A thermal-magnetic circuit breakers manufactured by Weidmüller with identical current ratings and pole configuration.
• Regulatory Compliance: The substitute part carries comprehensive international certifications (CE, CSA, TUV, UL489, VDE) meeting or exceeding the compliance profile of the obsolete part.
• Product Status: The substitute is classified as Active, ensuring continued availability and manufacturer support.
• Environmental Specifications: Both parts maintain MSL 1 classification, indicating equivalent moisture sensitivity performance.
• Trade Classification: Identical HTSUS and ECCN codes confirm equivalent tariff and export control treatment.

Frequently Asked Questions (FAQ)

Q: Why is BR1C30AC obsolete and what does this mean for system maintenance?

A: Obsolete status indicates the manufacturer has discontinued production. The BR1C30AC remains functional in existing installations but replacement stock is limited. The 2477970000 substitute ensures continued availability for maintenance and system upgrades.

Q: What are the critical parameters for substituting this circuit breaker?

A: The essential substitution criteria are: 30A current rating, single-pole configuration, thermal-magnetic breaker type, and AC/DC voltage compatibility. The 2477970000 meets all these requirements.

Q: Are there voltage rating differences between the main part and substitute?

A: The BR1C30AC voltage ratings are not specified in available documentation. The 2477970000 is rated for 277 V AC and 60 V DC. Verify that your system voltage requirements fall within these ratings before substitution.

Q: What is the mounting configuration of the substitute part?

A: The 2477970000 is configured for DIN Rail mounting with a lever actuator. Confirm that your installation supports DIN Rail mounting before selecting this substitute.

Q: Are there any compliance or certification differences?

A: The 2477970000 carries comprehensive international certifications (CE, CSA, TUV, UL489, VDE) and is RoHS Compliant. These certifications exceed the documented compliance profile of the obsolete BR1C30AC.

Q: Can the 2477970000 be used as a direct replacement in existing BR1C30AC installations?

A: Substitution is permissible where system voltage requirements align with the 277 V AC / 60 V DC ratings and DIN Rail mounting is available. Physical form factor and mounting compatibility must be confirmed for your specific application.
