Substitute Part Grouping Explanation

Substitute parts for the 104-PR3-10A are identified based on strict electrical and mechanical parameter matching. The primary substitution criteria are:

• Current Rating: 10A (exact match required)
• Voltage Rating - AC: 240V (exact match required)
• Voltage Rating - DC: 48V (exact match required)
• Breaker Type: Thermal (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 (exact match required)
• RoHS Status: ROHS3 Compliant (exact match required)

Mounting type variation (Through Hole versus Panel Mount) is permitted as a secondary parameter when all primary electrical and regulatory specifications are identical. Both substitute parts meet these criteria and are classified as Active products.

Parameter Comparison

Engineering Selection Recommendations

All three parts—104-PR3-10A, 104-PR-10A, and 106-M2-P30-10A—are Active products with identical electrical specifications and regulatory compliance. Selection between these parts is determined by mounting requirements:

• 104-PR3-10A and 104-PR-10A: Both feature through-hole mounting and are electrically and mechanically equivalent. Selection between these two is based on availability and procurement lead time.

• 106-M2-P30-10A: Provides panel-mount configuration while maintaining all electrical ratings and certifications. This part is suitable for applications requiring panel-mounted installation instead of through-hole mounting.

All parts carry full compliance with CE, CSA C22.2 No 235, GB 17701, IEC 60934, and UL1077 standards, and are ROHS3 compliant. Component selection should be based on specific mounting requirements and supply chain availability.

Frequently Asked Questions (FAQ)

Q: Can 104-PR-10A be used as a direct replacement for 104-PR3-10A?

A: Yes. Both parts are identical in electrical specifications (10A, 240V AC, 48V DC), breaker type (thermal), actuator type (push to reset), number of poles (1), mounting type (through hole), and regulatory compliance. They are parametric equivalents.

Q: What is the difference between 104-PR3-10A and 106-M2-P30-10A?

A: The primary difference is mounting type. The 104-PR3-10A uses through-hole mounting, while the 106-M2-P30-10A uses panel-mount configuration. All electrical ratings, certifications, and functional specifications are identical.

Q: Can 106-M2-P30-10A replace 104-PR3-10A in a through-hole application?

A: No. The 106-M2-P30-10A is designed for panel-mount installation and is not compatible with through-hole mounting requirements. Use only when panel-mount configuration is specified.

Q: Are all three parts ROHS3 compliant?

A: Yes. All three parts—104-PR3-10A, 104-PR-10A, and 106-M2-P30-10A—are ROHS3 compliant and carry identical regulatory certifications.

Q: What certifications do these circuit breakers carry?

A: All parts carry CE, CSA C22.2 No 235, GB 17701, IEC 60934, and UL1077 certifications, confirming compliance with international safety and performance standards.
