Substitute Part Grouping Explanation

Substitution eligibility for the SCHURTER 4404.0029 is determined by strict equivalence across the following parameters:

• Current Rating: 4A
• Voltage Rating - AC: 240V
• Voltage Rating - DC: 48V
• Breaker Type: Thermal
• Mounting Type: Panel Mount
• Actuator Type: Push to Reset
• Number of Poles: 1
• Approval Agencies: CSA C22.2 No 235, EN 60934, GB 17701, IEC 60934, UL1077

The substitute part 4404.0019 meets all electrical and mechanical requirements for direct replacement. Both parts are manufactured by SCHURTER Inc., maintain identical functional specifications, and carry equivalent regulatory certifications. The difference in series designation (T9-711 vs. T9-311) reflects internal product line evolution while preserving electrical and mechanical compatibility.
