Key Parameters

Substitute Part Grouping Explanation

Substitution of the SCHURTER 4430.1077 is determined by strict equivalence across the following parameters: breaker type (thermal), voltage ratings (240 V AC / 60 V DC), actuator type (pushbutton), mounting configuration (panel mount), pole count (2), series designation (TA45), and manufacturer (SCHURTER Inc.). Parts meeting all these criteria are classified as parametric equivalents and are fully interchangeable within the specified electrical and mechanical constraints. The substitute parts 4430.125 and 4430.2643 satisfy all substitution criteria and maintain identical functional and compliance characteristics.

Parameter Comparison

Engineering Selection Recommendations

All three parts—4430.1077, 4430.125, and 4430.2643—are Active status products manufactured by SCHURTER Inc. and carry identical regulatory approvals including CSA C22.2 No 235, EN 60934, GB 17701, IEC 60934, and UL1077 certifications. All parts are ROHS3 compliant and REACH unaffected. Selection among these equivalents may be based on inventory availability: 4430.1077 (758 pcs), 4430.125 (946 pcs), or 4430.2643 (887 pcs). No technical differentiation exists between these parts; they are direct parametric equivalents suitable for interchangeable use in applications requiring 240 V AC / 60 V DC thermal circuit protection with pushbutton panel mount actuation.

Frequently Asked Questions (FAQ)

Q: Are parts 4430.125 and 4430.2643 direct replacements for 4430.1077? A: Yes. Both parts are parametric equivalents meeting identical electrical specifications (240 V AC, 60 V DC), mechanical configuration (2-pole, pushbutton, panel mount), and regulatory certifications. They are fully interchangeable.

Q: What parameters define substitutability for this circuit breaker? A: Substitutability is determined by: breaker type (thermal), AC voltage rating (240 V), DC voltage rating (60 V), actuator type (pushbutton), mounting type (panel mount), pole count (2), series (TA45), and manufacturer (SCHURTER Inc.). All substitute parts match these criteria exactly.

Q: Do all three parts carry the same certifications? A: Yes. All parts are certified to CSA C22.2 No 235, EN 60934, GB 17701, IEC 60934, and UL1077, with identical ROHS3 compliance and REACH unaffected status.

Q: Is there a difference in packaging between these parts? A: No. All three parts are supplied in Bulk packaging with no differentiation in package type or configuration.

Q: Can I use these parts interchangeably in existing designs? A: Yes. Since all electrical, mechanical, and compliance parameters are identical, these parts can be used interchangeably without design modification or re-qualification.
