Key Parameters

Substitute Part Grouping Explanation

All substitute parts for SCHURTER 4400.029 are parametric equivalents within the T11 series. Substitution is based on identical electrical and mechanical parameters: 4A current rating, 240V AC and 48V DC voltage ratings, thermal breaker type, single-pole configuration, panel mount design, and push-to-reset actuation. These parts share the same approval agencies (CSA C22.2 No 235, EN 60934, GB 17701, IEC 60934, UL1077), RoHS3 compliance status, and REACH unaffected classification. The substitute parts are 4400.0001, 4400.0025, and 4400.0185, all manufactured by SCHURTER Inc. with Active product status.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts (4400.0001, 4400.0025, 4400.0185) are direct equivalents to SCHURTER 4400.029 and are suitable for replacement in applications requiring thermal circuit protection at 4A, 240V AC, and 48V DC. Selection among these parts may be based on inventory availability and lead time considerations. All parts maintain Active product status and comply with the same international safety standards. RoHS3 compliance and REACH unaffected status are consistent across all options, ensuring regulatory compliance in restricted substance applications.

Frequently Asked Questions (FAQ)

Q: Can SCHURTER 4400.0001, 4400.0025, or 4400.0185 be used as direct replacements for SCHURTER 4400.029?

A: Yes. All three parts are parametric equivalents with identical electrical ratings (4A, 240V AC, 48V DC), thermal breaker type, single-pole configuration, panel mount design, and push-to-reset actuation. They share the same approval certifications and compliance status.

Q: What are the key parameters that determine substitution eligibility?

A: Current rating (4A), AC voltage rating (240V), DC voltage rating (48V), breaker type (thermal), mounting type (panel mount), actuator type (push to reset), and number of poles (1) must remain identical for direct substitution.

Q: Are there any differences in compliance certifications between the main part and substitutes?

A: SCHURTER 4400.029, 4400.0001, and 4400.0185 all list CSA C22.2 No 235, EN 60934, GB 17701, IEC 60934, and UL1077 approvals. All parts are ROHS3 compliant and REACH unaffected.

Q: What is the packaging format for these parts?

A: All parts are supplied in Bulk packaging.

Q: Are there inventory differences among the substitute parts?

A: Yes. SCHURTER 4400.029 has 813 pieces in stock, 4400.0001 has 765 pieces, 4400.0025 has 1215 pieces, and 4400.0185 has 1251 pieces available as new original stock.
