Substitute Part Grouping Explanation

Substitution of the SCHURTER 4435.0074 is determined by strict equivalence across the following critical parameters:

• Current Rating: 20A (exact match required)
• Voltage Rating AC: 240V (exact match required)
• Voltage Rating DC: 60V (exact match required)
• Breaker Type: Thermal (exact match required)
• Mounting Type: Panel Mount (exact match required)
• Actuator Type: Rotary (exact match required)
• Number of Poles: 2 (exact match required)
• Series: TA35 (same product family)

The substitute part 4435.0123 meets all these criteria, establishing it as a parametric equivalent within the TA35 series.
