Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SCHURTER 4430.251 is determined by strict equivalence across the following parameters:

• Voltage Rating - AC: 240 V
• Voltage Rating - DC: 60 V
• Breaker Type: Thermal
• Actuator Type: Pushbutton
• Mounting Type: Panel Mount
• Number of Poles: 2
• Series: TA45
• Manufacturer: SCHURTER Inc.

All identified substitute parts match these specifications without deviation. Parts 4430.125 and 4430.2643 are parametric equivalents within the TA45 series and maintain identical electrical and mechanical characteristics required for direct substitution in applications utilizing the 4430.251.

Parameter Comparison

Frequently Asked Questions (FAQ)

Q: Can 4430.125 or 4430.2643 be used as direct replacements for 4430.251?

A: Yes. Both parts are parametric equivalents with identical electrical ratings (240 V AC, 60 V DC), breaker type (thermal), actuator configuration (pushbutton), mounting method (panel mount), and pole count (2). All three parts belong to the TA45 series and carry the same regulatory approvals.

Q: Are there differences in compliance or certification between these parts?

A: No. All three parts hold identical certifications: CSA C22.2 No 235, EN 60934, GB 17701, IEC 60934, and UL1077. All are ROHS3 Compliant and REACH Unaffected.

Q: What determines substitution eligibility for this circuit breaker?

A: Substitution is determined by matching voltage ratings (240 V AC and 60 V DC), breaker type (thermal), actuator type (pushbutton), mounting configuration (panel mount), pole count (2), and series designation (TA45). All identified substitutes meet these criteria without exception.

Q: Are packaging and inventory considerations relevant to substitution?

A: Packaging is identical (Bulk) across all three parts. Inventory levels differ but do not affect technical substitutability. Selection may consider stock availability for procurement planning.

Q: Can these parts be used in applications outside their rated voltage specifications?

A: No. These components are rated specifically for 240 V AC and 60 V DC operation. Use only within these electrical parameters.
