Key Parameters

Substitute Part Grouping Explanation

The substitute part 2478130000 qualifies as a functional equivalent based on the following critical parameters:

• Current Rating: Both parts are rated at 7A
• Voltage Rating - AC: Both parts support 480V AC operation
• Number of Poles: Both are 2-pole configurations
• Mounting Type: Both use DIN rail mounting
• Actuator Type: Both feature lever actuation
• Manufacturer: Both are manufactured by Weidmüller

The substitute part (2478130000) is from the MCB 489 series and is currently in active production status, providing a modern alternative to the obsolete BR2C7AC. The substitute adds DC voltage capability (125V DC) and thermal-magnetic breaker technology, representing an enhanced specification while maintaining backward compatibility with the core electrical and mechanical parameters.

Parameter Comparison

Engineering Selection Recommendations

The 2478130000 (MCB 489 series) is the designated substitute for the obsolete BR2C7AC. Selection is based on:

• Electrical equivalence: Identical 7A current rating and 480V AC voltage rating
• Mechanical compatibility: Matching 2-pole, DIN rail, lever-actuated configuration
• Product availability: Active production status ensures supply continuity
• Regulatory compliance: The substitute carries multiple international certifications (CE, CSA, TUV, UL489, VDE) and RoHS compliance, meeting modern regulatory requirements
• Enhanced capability: The addition of 125V DC rating and thermal-magnetic protection provides expanded operational flexibility without compromising AC circuit protection performance

Frequently Asked Questions (FAQ)

Q: Can the 2478130000 directly replace the BR2C7AC in existing installations?

A: Yes. Both parts share identical current rating (7A), AC voltage rating (480V), pole configuration (2-pole), mounting type (DIN rail), and actuation method (lever). The substitute is mechanically and electrically compatible for direct replacement.

Q: What is the significance of the thermal-magnetic breaker type in the substitute?

A: The 2478130000 specifies thermal-magnetic protection, whereas the BR2C7AC does not provide this detail in available documentation. Thermal-magnetic breakers combine thermal overload protection with magnetic short-circuit protection, representing standard modern circuit breaker technology.

Q: Does the 125V DC rating of the substitute affect AC-only applications?

A: No. The 125V DC rating is an additional capability that does not impact AC circuit protection performance. In AC-only applications, this parameter remains unused and does not affect system operation.

Q: Why is the BR2C7AC listed as obsolete?

A: Obsolescence indicates the part is no longer in active production. The MCB 489 series substitute (2478130000) represents Weidmüller's current product line for this application category.

Q: Are there packaging differences between these parts?

A: The BR2C7AC packaging is not specified, while the 2478130000 is supplied in bulk packaging. Packaging format does not affect electrical or mechanical performance.

Q: What certifications does the substitute carry?

A: The 2478130000 carries CE, CSA C22.2 No 5, CSA C22.2 No 235, TUV, UL489, and VDE certifications, plus RoHS compliance. These certifications confirm compliance with international electrical safety and environmental standards.
