Circuit Breaker Thermal 7A 240VAC 48VDC SCHURTER 4400.0028

Part Overview

The SCHURTER 4400.0028 is a single-pole thermal circuit breaker rated for 7A at 240V AC and 48V DC, designed for panel mount applications with push-to-reset actuation. This component is classified as Active product status and carries full compliance with international safety standards including UL1077, IEC 60934, EN 60934, CSA C22.2 No 235, and GB 17701. The thermal breaker type provides automatic overcurrent protection through thermal sensing mechanisms. Equivalent substitute parts are necessary when primary inventory is unavailable, when supply chain optimization is required, or when design flexibility across compatible series is needed while maintaining identical electrical and mechanical performance.

Substitute Part Grouping Explanation

Substitution eligibility for thermal circuit breakers in this category is determined by strict equivalence across the following parameters: current rating (7A), AC voltage rating (240V), DC voltage rating (48V), breaker type (thermal), mounting configuration (panel mount), actuator mechanism (push to reset), and pole count (single pole). All three parts—4400.0028, 4400.0191, and 4404.006—meet these criteria identically. The primary distinction between substitute parts lies in series designation (T11 versus T9-611) and minor variations in compliance documentation and inventory status. Series differences do not affect electrical or mechanical compatibility within this thermal breaker category.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain Active product status and carry identical compliance certifications (UL1077, IEC 60934, EN 60934, CSA C22.2 No 235, GB 17701 for 4400.0028 and 4404.006; equivalent compliance for 4400.0191). All parts are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements. Selection between 4400.0028 and 4400.0191 (both T11 series) is interchangeable from an engineering perspective. The 4404.006 (T9-611 series) provides an alternative within the same electrical and mechanical specifications. Component selection should be based on inventory availability, lead time requirements, and procurement cost optimization, as all three parts deliver identical functional performance in 7A thermal circuit breaker applications at 240V AC and 48V DC ratings.

Frequently Asked Questions (FAQ)

Q: Can 4400.0191 be used as a direct replacement for 4400.0028? A: Yes. Both parts are T11 series thermal circuit breakers with identical electrical ratings (7A, 240V AC, 48V DC), mounting configuration (panel mount), and actuator type (push to reset). They are parametrically equivalent.

Q: What is the difference between the T11 series (4400.0028, 4400.0191) and T9-611 series (4404.006)? A: The series designation reflects internal design architecture, but all three parts meet identical electrical and mechanical specifications for this application. Series differences do not affect compatibility or performance in circuits requiring 7A thermal protection at the specified voltage ratings.

Q: Are all three parts suitable for both AC and DC applications? A: Yes. All three parts carry dual voltage ratings: 240V AC and 48V DC. They are suitable for circuits operating at either voltage or mixed AC/DC environments within these ratings.

Q: Do these parts require any special handling or storage considerations? A: All parts are classified as Not Applicable or Vendor Undefined for Moisture Sensitivity Level, indicating standard handling procedures are appropriate. Bulk packaging is standard for all three parts.

Q: Which part should be selected for new designs? A: Any of the three parts may be selected for new designs. All carry Active product status and full compliance certifications. Selection should be based on supplier availability, lead time, and cost considerations, as electrical and mechanical performance is identical across all three options.
