Substitute Part Grouping Explanation

Substitution eligibility for SCHURTER thermal circuit breakers in the TA45 series is determined by strict equivalence across the following parameters:

Current Rating: 16A (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: Rocker (exact match required)
Number of Poles: 2 (exact match required)
Series: TA45 (exact match required)
Manufacturer: SCHURTER Inc. (exact match required)

All identified substitute parts meet these criteria without exception. Substitution is valid for direct replacement in applications where the main part number 4430.1252 is specified.

Frequently Asked Questions (FAQ)

Q: Can any of these substitute parts be used as a direct replacement for SCHURTER 4430.1252?

A: Yes. All listed substitute parts are parametric equivalents with identical electrical ratings (16A, 240V AC, 60V DC), breaker type (thermal), mounting configuration (panel mount rocker), and pole count (2-pole). Direct substitution is valid without circuit modification.

Q: What determines whether a part qualifies as a substitute?

A: Substitution is based on exact equivalence across current rating, voltage ratings (AC and DC), breaker type, mounting type, actuator type, pole count, and series designation. All substitute parts match these parameters precisely.

Q: Are there differences in approval certifications among the substitute parts?

A: Most substitute parts carry identical certifications (CSA C22.2 No 235, EN 60934, GB 17701, IEC 60934, UL1077). Part 4430.1563 and 4430.1729 do not list approval agency data in the provided specifications but maintain all other equivalent parameters and ROHS3 compliance.

Q: What is the packaging format for these parts?

A: All parts are supplied in Bulk packaging format.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All substitute parts carry ROHS3 Compliant status. The main part 4430.1252 and all substitutes meet REACH Unaffected status and carry EAR99 ECCN classification.

Q: Which substitute part has the best inventory availability?

A: Part 4430.1296 has the highest current inventory at 1130 pieces. For procurement planning, inventory levels range from 676 to 1130 pieces across all substitute options.
