Key Parameters

Substitute Part Grouping Explanation

The SCHURTER 4410.9022 qualifies as a parametric equivalent to the 4410.9021 based on the following critical substitution criteria:

• Current Rating: Both rated at 15A
• Voltage Rating - AC: Both rated at 240V
• Voltage Rating - DC: Both rated at 28V
• Mounting Type: Both panel mount configuration
• Actuator Type: Both push-push operation
• Number of Poles: Both single pole
• Illumination: Both blue illumination at 24V nominal
• Breaker Type: Both thermal operation
• RoHS Compliance: Both ROHS3 compliant
• Regulatory Approvals: Both meet IEC 60934, EN 60934, GB 17701, and UL1077

The primary difference between these models is the series designation (T12-MSM versus TM12-MSM) and the specific approval agency certifications listed, with 4410.9022 excluding CSA C22.2 No 235 certification.

Parameter Comparison

Engineering Selection Recommendations

Both the 4410.9021 and 4410.9022 are Active status products manufactured by SCHURTER Inc. and meet the core electrical and mechanical requirements for 15A thermal circuit breaker applications at 240V AC and 28V DC. Selection between these models should be based on:

1. Regulatory Requirements: If CSA C22.2 No 235 certification is mandated for your application, the 4410.9021 is the required choice. For applications requiring only IEC 60934, EN 60934, GB 17701, and UL1077 compliance, either model is acceptable.

2. Supply Chain Availability: The 4410.9022 maintains higher inventory levels (1150 pcs versus 680 pcs), making it preferable for applications without specific CSA certification requirements.

3. Series Compatibility: Verify that your system design does not specify a particular series designation (T12-MSM or TM12-MSM) before substitution.

Frequently Asked Questions (FAQ)

Q: Can the 4410.9022 be used as a direct replacement for the 4410.9021?

A: Yes, provided your application does not require CSA C22.2 No 235 certification. All electrical parameters, mechanical specifications, and primary regulatory approvals are identical between the two models.

Q: What is the difference between the T12-MSM and TM12-MSM series?

A: The series designation indicates internal design variants within SCHURTER's product line. Both series meet the specified electrical and mechanical parameters for this 15A thermal breaker application. Consult your system documentation to determine if a specific series is required.

Q: Are both models RoHS compliant?

A: Yes, both the 4410.9021 and 4410.9022 are ROHS3 compliant.

Q: What certifications does each model hold?

A: The 4410.9021 holds CSA C22.2 No 235, EN 60934, GB 17701, IEC 60934, and UL1077 certifications. The 4410.9022 holds EN 60934, GB 17701, IEC 60934, and UL1077 certifications. Both meet UL1077 and IEC 60934 standards.

Q: Is the illumination voltage the same for both models?

A: Yes, both models feature blue illumination at 24V nominal voltage.

Q: Can these breakers be used in both AC and DC circuits?

A: Yes, both models are rated for 240V AC and 28V DC operation, allowing use in mixed voltage environments within these specifications.
