• Voltage Rating - DC: 60V (exact match required)
• Breaker Type: Thermal (exact match required)
• Mounting Type: Panel Mount (exact match required)
• Actuator Type: Pushbutton (exact match required)
• Number of Poles: 2 (exact match required)
• Series: TA45 (same product family)

The identified substitute part 4430.3309 meets all electrical and mechanical parameters specified above, confirming functional and physical interchangeability within the TA45 series.

Parameter Comparison

Engineering Selection Recommendations

Both the 4430.105 and 4430.3309 are Active status components manufactured by SCHURTER within the TA45 series. Selection between these parts should be based on inventory availability and supply chain requirements, as all electrical specifications, mechanical interfaces, and regulatory compliance certifications are identical.

The 4430.105 carries certifications under CSA C22.2 No 235, EN 60934, GB 17701, IEC 60934, and UL1077. Both parts maintain ROHS3 compliance and REACH Unaffected status, confirming suitability for applications requiring environmental and regulatory adherence.

When the primary part number is unavailable, the 4430.3309 substitute provides equivalent performance and compatibility without design modification or system reconfiguration.

Frequently Asked Questions (FAQ)

Q: Can 4430.3309 be used as a direct replacement for 4430.105?

A: Yes. Both parts are identical in all critical electrical parameters (7A current rating, 240V AC / 60V DC voltage ratings), mechanical configuration (panel mount, pushbutton actuator, 2-pole), and regulatory compliance. No circuit modification is required.

Q: Are there any differences in certifications between these parts?

A: The 4430.105 lists specific approval agencies (CSA C22.2 No 235, EN 60934, GB 17701, IEC 60934, UL1077). Both parts maintain ROHS3 compliance and REACH Unaffected status. Verify certification documentation if specific agency approval is a system requirement.

Q: What determines if a part can substitute for the 4430.105?

A: Substitution requires exact equivalence in current rating (7A), AC voltage (240V), DC voltage (60V), breaker type (thermal), mounting configuration (panel mount), actuator type (pushbutton), and pole count (2). Any deviation in these parameters disqualifies a part from substitution.

Q: Are packaging differences relevant to substitution?

A: Both parts are supplied in Bulk packaging. Packaging format does not affect electrical or mechanical compatibility. Confirm packaging requirements based on procurement and assembly processes.

Q: What is the inventory status for each part?

A: The 4430.105 has 1163 pieces in stock. The 4430.3309 has 912 pieces in stock. Both are listed as New Original inventory.
