E-T-A 105-P30-2A Circuit Breaker Thermal Equivalent & Substitute Parts

Part Overview

The E-T-A 105-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 actively manufactured and holds Active product status. Equivalent and substitute parts within the E-T-A product line provide alternative sourcing options when the primary part number is unavailable or when inventory requirements necessitate alternative series selection.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 105-P30-2A is determined by matching the following critical parameters: current rating (2A), AC voltage rating (240V), DC voltage rating (48V), breaker type (thermal), mounting configuration (panel mount), actuation method (push to reset), and pole count (1). All identified substitute parts maintain identical electrical and mechanical specifications across these parameters. Substitutes differ only in series designation (104 and 106 series versus the primary 105 series), reflecting manufacturing line variations within E-T-A's product portfolio while preserving functional equivalence.

Parameter Comparison

Engineering Selection Recommendations

All three part numbers—105-P30-2A, 104-P10-2A, and 106-M2-P10-2A—are functionally equivalent for applications requiring a 2A thermal circuit breaker at 240V AC and 48V DC with panel mount configuration. Each part maintains Active product status and carries identical regulatory approvals (CE, CSA C22.2 No 235, GB 17701, IEC 60934, UL1077) and ROHS3 compliance. Selection between these parts should be based on availability and inventory levels rather than electrical or mechanical performance differences. The 106-M2-P10-2A currently maintains the highest inventory level at 1427 pieces, followed by 104-P10-2A at 1033 pieces, and 105-P30-2A at 882 pieces.

Frequently Asked Questions (FAQ)

Q: Can 104-P10-2A and 106-M2-P10-2A be used interchangeably with 105-P30-2A?

A: Yes. All three parts share identical electrical ratings (2A, 240V AC, 48V DC), breaker type (thermal), mounting configuration (panel mount), actuation method (push to reset), and regulatory approvals. They are parametric equivalents suitable for direct substitution in circuit protection applications.

Q: What determines whether a part qualifies as a substitute for the 105-P30-2A?

A: Substitution eligibility requires matching current rating, AC and DC voltage ratings, breaker type, mounting type, actuator type, pole count, and regulatory compliance. All identified substitutes meet these criteria.

Q: Are there packaging differences between these part numbers?

A: All three parts are supplied in Bulk packaging. No packaging format differences exist between the main part and its substitutes.

Q: Do these parts carry the same regulatory certifications?

A: Yes. The 105-P30-2A, 104-P10-2A, and 106-M2-P10-2A all carry CE, CSA C22.2 No 235, GB 17701, IEC 60934, and UL1077 approvals, and all are ROHS3 compliant.

Q: What is the difference between the 105, 104, and 106 series designations?

A: Series designation reflects E-T-A's internal product line organization. From an electrical and mechanical standpoint, these series variants are functionally equivalent when specifications match across all critical parameters.
