Key Parameters

Substitute Part Grouping Explanation

Substitution of the BR2D20AC is based on the following critical parameters that must align between the main part and substitute:

• Number of Poles: 2-pole configuration
• Current Rating: 20A nominal rating
• Breaker Type: Thermal Magnetic operation
• Voltage Ratings: AC and DC voltage compatibility
• Mounting Type: DIN Rail mounting
• Regulatory Compliance: CE, CSA, TUV, UL489, VDE certifications
• Environmental Classification: Moisture Sensitivity Level 1

The substitute part 2478940000 maintains functional equivalence through matching these core electrical and mechanical parameters while offering active product status and continued manufacturer support.

Parameter Comparison

Engineering Selection Recommendations

The BR2D20AC is obsolete and no longer supported by the manufacturer. The substitute part 2478940000 is an active product offering equivalent electrical performance through matching pole count, current rating, and thermal-magnetic protection characteristics. Both components share identical Moisture Sensitivity Level classification and REACH compliance status.

Selection of 2478940000 is supported by active product status, RoHS compliance, and comprehensive regulatory approvals including CE, CSA C22.2 No 5, CSA C22.2 No 235, TUV, UL489, and VDE certifications. The substitute maintains DIN Rail mounting compatibility and lever actuation for direct integration into existing installations.
