Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 106-M2-P30-0.3A is determined by strict equivalence across the following critical parameters:

• Current Rating: 300mA (exact match required)
• Voltage Rating - AC: 240V (exact match required)
• Voltage Rating - DC: 48V (exact match required)
• Breaker Type: Thermal (exact match required)
• Mounting Type: Panel Mount (exact match required)
• Actuator Type: Push to Reset (exact match required)
• Number of Poles: 1 (exact match required)
• Approval Agencies: CE, CSA C22.2 No 235, GB 17701, IEC 60934, UL1077 (all certifications must be present)
• RoHS Status: ROHS3 Compliant (exact match required)

The substitute part 106-M2-P10-0.3A meets all these criteria and is therefore a direct parametric equivalent within the E-T-A 106 series.

Parameter Comparison

Engineering Selection Recommendations

Both the 106-M2-P30-0.3A and 106-M2-P10-0.3A are Active product status components manufactured by E-T-A within the same 106 series. Both parts carry identical electrical ratings, mechanical specifications, and regulatory certifications. Selection between these parts can be made based on inventory availability and supply chain requirements without compromising electrical performance, safety compliance, or mechanical fit in panel mount applications. Both parts maintain ROHS3 compliance and are unaffected by REACH regulations.

Frequently Asked Questions (FAQ)

Q: Can the 106-M2-P10-0.3A be used as a direct replacement for the 106-M2-P30-0.3A?

A: Yes. Both parts are parametric equivalents with identical current ratings (300mA), voltage ratings (240V AC / 48V DC), breaker type (thermal), mounting configuration (panel mount), and regulatory certifications. Direct substitution is supported without circuit redesign or mechanical modification.

Q: Are there any differences in the approval certifications between these parts?

A: No. Both parts carry identical certifications: CE, CSA C22.2 No 235, GB 17701, IEC 60934, and UL1077. Regulatory compliance is equivalent across both models.

Q: What is the significance of the part number suffix difference (P30 vs P10)?
