BR2C5AC Equivalent & Substitute Parts

Part Overview

The BR2C5AC is a 2-pole circuit breaker with C-curve characteristic and 5A current rating manufactured by Weidmüller. This component is classified as obsolete, making identification of functionally equivalent alternatives essential for system maintenance and component procurement. The BR2C5AC serves as a branch protection device in AC/DC applications and requires substitution with active product lines that maintain electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the BR2C5AC is based on the following critical parameters that must align for functional equivalence:

• Number of Poles: 2-pole configuration
• Current Rating: 5A nominal
• Breaker Type: Thermal Magnetic operation
• Curve Characteristic: C-curve (standard industrial protection)
• Voltage Compatibility: AC and DC rated operation
• Mounting Standard: DIN Rail compatibility
• Regulatory Compliance: CE, CSA, TUV, UL489, VDE certifications

The substitute part 2478110000 from the MCB 489 series satisfies all substitution criteria through matching pole count, current rating, thermal-magnetic operation, and regulatory approvals. This part maintains the same HTSUS classification and REACH status as the original component.

Parameter Comparison

Engineering Selection Recommendations

The 2478110000 (MCB 489 series) is the direct active substitute for the obsolete BR2C5AC. Selection is based on:

• Electrical Equivalence: Identical 2-pole, 5A thermal-magnetic configuration
• Regulatory Compliance: Comprehensive certification portfolio (CE, CSA, TUV, UL489, VDE) ensures compliance in regulated applications
• Product Lifecycle: Active status ensures long-term availability and supply chain continuity
• Environmental Compliance: RoHS compliance and REACH unaffected status meet current regulatory requirements
• Mechanical Compatibility: DIN Rail mounting and lever actuator provide direct installation compatibility

Frequently Asked Questions (FAQ)

Q: Can the 2478110000 directly replace the BR2C5AC in existing installations?

A: Yes. Both components share identical pole count (2), current rating (5A), and thermal-magnetic operation. The 2478110000 maintains DIN Rail mounting compatibility and lever actuation, enabling direct substitution without circuit redesign.

Q: What certifications apply to the substitute part?

A: The 2478110000 carries CE, CSA C22.2 No 5, CSA C22.2 No 235, TUV, UL489, and VDE approvals, providing compliance for North American and European applications.

Q: Are there voltage rating differences between the parts?

A: The BR2C5AC specifications do not include explicit voltage ratings. The 2478110000 is rated 480 V AC and 125 V DC, which covers standard industrial voltage ranges. Verify application voltage requirements against these ratings.

Q: What is the packaging difference?

A: The BR2C5AC is listed with dash packaging (standard), while the 2478110000 is supplied in bulk packaging. This reflects the transition from obsolete to active product lines and does not affect electrical function.

Q: Is the 2478110000 RoHS compliant?

A: Yes. The 2478110000 is RoHS compliant, meeting current environmental regulations. The BR2C5AC MSL rating of 1 (Unlimited) is maintained in the substitute part.
