Key Parameters

Substitute Part Grouping Explanation

Substitute relationships for the SCHURTER 4400.0042 are established based on matching electrical and mechanical parameters. The primary substitution criteria are:

• Current Rating: 800mA
• Voltage Rating - AC: 240V
• Voltage Rating - DC: 48V
• Breaker Type: Thermal
• Mounting Type: Panel Mount
• Actuator Type: Push to Reset
• Number of Poles: 1

Parametric Equivalents (SCHURTER 4400.0323 and SCHURTER 4400.0614) share identical electrical specifications and mechanical form factors with the main part, differing only in internal design revision or manufacturing batch designation within the T11 series.

Similar Substitute (E-T-A 106-M2-P10-0.8A) meets all core electrical and mechanical parameters but originates from a different manufacturer with distinct approval agency certifications.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts maintain active product status and ROHS3 compliance. The SCHURTER parametric equivalents (4400.0323 and 4400.0614) are direct alternatives within the same manufacturer's T11 series and carry identical electrical and mechanical specifications.

The E-T-A 106-M2-P10-0.8A represents a cross-manufacturer alternative that meets all specified electrical and mechanical parameters. This part carries approval certifications including CE, CSA C22.2 No 235, GB 17701, IEC 60934, and UL1077, providing regulatory alignment for applications requiring multi-standard compliance.

Selection between SCHURTER and E-T-A alternatives depends on application-specific certification requirements, supply chain preferences, and inventory availability. All parts are available in bulk packaging with current stock levels documented.

Frequently Asked Questions (FAQ)

Q: Can SCHURTER 4400.0323 and 4400.0614 be used interchangeably with 4400.0042?

A: Yes. These parts are parametric equivalents sharing identical current rating (800mA), voltage ratings (240V AC / 48V DC), thermal breaker type, panel mount configuration, push-to-reset actuation, and single-pole design. They differ only in internal design revision within the T11 series.

Q: What are the key differences between SCHURTER and E-T-A alternatives?

A: Both manufacturers provide 800mA thermal circuit breakers with 240V AC / 48V DC ratings in panel mount configuration. The primary difference is manufacturer origin and associated approval agency certifications. E-T-A includes CE marking alongside CSA, GB, IEC, and UL certifications, while SCHURTER parts reference CSA, EN, GB, IEC, and UL standards.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed parts—SCHURTER 4400.0042, 4400.0323, 4400.0614, and E-T-A 106-M2-P10-0.8A—are ROHS3 compliant and REACH unaffected.

Q: What packaging is available for these circuit breakers?

A: All substitute parts are supplied in bulk packaging. Current inventory levels are documented: SCHURTER 4400.0042 (680 pcs), SCHURTER 4400.0323 (1242 pcs), SCHURTER 4400.0614 (777 pcs), and E-T-A 106-M2-P10-0.8A (1170 pcs).

Q: Can the E-T-A 106-M2-P10-0.8A be used in applications requiring SCHURTER certification?

A: The E-T-A part meets the same electrical and mechanical specifications and carries overlapping regulatory certifications (CSA C22.2 No 235, GB 17701, IEC 60934, UL1077). Application-specific certification requirements must be evaluated based on end-use regulatory standards.
