E-T-A 106-M3-P30-2A Circuit Breaker Thermal Equivalent & Substitute Parts

Part Overview

The E-T-A 106-M3-P30-2A is a thermal circuit breaker rated for 2A at 240V AC and 48V DC, designed for panel mount applications with push-to-reset actuation. This single-pole breaker is classified as Active product status and carries multiple international approvals including CE, CSA C22.2 No 235, GB 17701, IEC 60934, and UL1077 certifications. Substitute parts are identified when equivalent electrical and mechanical parameters are maintained across the same voltage and current specifications, allowing for interchangeability in circuit protection applications.

Substitute Part Grouping Explanation

Substitute parts for the 106-M3-P30-2A are qualified based on strict electrical and mechanical parameter equivalence. The critical parameters determining substitutability are:

• Current Rating: 2A (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 (exact match required)
• RoHS Status: ROHS3 Compliant (exact match required)

Two substitute parts meet all substitution criteria: the 104-P10-2A (Series 104) and the 106-M2-P10-2A (Series 106). Both maintain identical electrical specifications, mechanical configuration, and regulatory compliance as the primary part.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts are qualified for direct replacement of the 106-M3-P30-2A based on identical electrical ratings, mechanical configuration, and regulatory compliance. All three parts maintain Active product status and carry the same international certifications (CE, CSA C22.2 No 235, GB 17701, IEC 60934, UL1077), ensuring compliance with applicable standards. The 104-P10-2A represents a cross-series alternative within the E-T-A thermal breaker portfolio, while the 106-M2-P10-2A remains within the same 106 series. Selection between these options may be determined by inventory availability and application-specific mechanical interface requirements, as all electrical and safety parameters are equivalent.

Frequently Asked Questions (FAQ)

Q: Can the 104-P10-2A be used as a direct replacement for the 106-M3-P30-2A?

A: Yes. The 104-P10-2A meets all substitution criteria with identical current rating (2A), voltage ratings (240V AC / 48V DC), thermal breaker type, panel mount configuration, push-to-reset actuation, and regulatory approvals. The difference in series designation (104 vs. 106) does not affect electrical or mechanical compatibility.

Q: What are the critical parameters that must match for substitution?

A: Current rating, AC voltage rating, DC voltage rating, breaker type, mounting type, actuator type, number of poles, and regulatory approvals must all match exactly. Any deviation in these parameters disqualifies a part from substitution.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. Both the 104-P10-2A and 106-M2-P10-2A are ROHS3 compliant, matching the compliance status of the primary part 106-M3-P30-2A.

Q: Do the substitute parts carry the same certifications?

A: Yes. All three parts carry identical certifications: CE, CSA C22.2 No 235, GB 17701, IEC 60934, and UL1077.

Q: What is the difference between the 106-M3-P30-2A and 106-M2-P10-2A if they are in the same series?

A: Both parts are in the 106 series and share identical electrical and mechanical specifications. The difference in model designation (M3-P30 vs. M2-P10) reflects internal design variations within the series that do not affect functional equivalence for circuit protection applications.
