ESS20-002-DC24V-3A Equivalent & Substitute Parts

Part Overview

The ESS20-002-DC24V-3A is a solid state circuit breaker manufactured by E-T-A, rated for 3A at 24VDC with push-push actuator control. This component is classified as obsolete, making identification of suitable substitute parts essential for ongoing system maintenance and new design implementations. The push-push actuator configuration and 32V DC voltage rating define its operational envelope within industrial control applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ESS20-002-DC24V-3A is determined by the following critical parameters:

• Current Rating: Must be 3A minimum
• Voltage Rating - DC: Must be 30V or higher (original rated 32V)
• Breaker Type: Solid state technology required
• Number of Poles: Single pole configuration
• Mounting Type: Holder-based mounting
• Approval Certifications: IEC 60934 and UL1077 compliance required

The ESS30-S003-DC24V-3A qualifies as a manufacturer-recommended substitute based on matching current rating, exceeding voltage requirements, maintaining solid state architecture, and preserving single-pole holder mounting with equivalent certifications.

Parameter Comparison

Engineering Selection Recommendations

The ESS30-S003-DC24V-3A is the manufacturer-recommended substitute for the obsolete ESS20-002-DC24V-3A. Both components maintain identical current ratings (3A) and single-pole solid state architecture with equivalent regulatory certifications (IEC 60934, UL1077). The substitute operates at 30V DC, which is within acceptable tolerance for 24VDC nominal applications given the 32V original specification. Both components are ROHS3 compliant and REACH unaffected.

The primary operational difference is the actuator interface: the original uses push-push control while the substitute employs pushbutton actuation. The substitute provides expanded illumination options (Green, Orange, Red versus Green, Orange), offering enhanced status indication capability. The substitute's active product status ensures continued availability and supply chain reliability compared to the obsolete original.

Frequently Asked Questions (FAQ)

Q: Can the ESS30-S003-DC24V-3A directly replace the ESS20-002-DC24V-3A in existing installations?

A: Direct mechanical and electrical substitution is supported based on matching current rating (3A), solid state breaker type, single-pole configuration, and holder mounting. The 30V DC rating of the substitute accommodates 24VDC nominal operation. Actuator interface differences (push-push versus pushbutton) require mechanical panel integration assessment.

Q: What is the voltage compatibility between the 32V original and 30V substitute?

A: The substitute's 30V DC rating is suitable for 24VDC nominal applications. The original 32V specification provides 8V margin above nominal; the substitute provides 6V margin. Both operate within standard industrial 24VDC system tolerances.

Q: Are the illumination differences between the two models significant?

A: The substitute provides three illumination colors (Green, Orange, Red) compared to the original's two colors (Green, Orange). This expanded indication capability does not affect electrical substitution but may require panel design consideration if specific color coding is required.

Q: Do both components meet the same regulatory standards?

A: Both the ESS20-002-DC24V-3A and ESS30-S003-DC24V-3A are certified to IEC 60934 and UL1077, with ROHS3 compliance and REACH unaffected status. Regulatory equivalence is established.

Q: What packaging is available for the substitute part?

A: The ESS30-S003-DC24V-3A is supplied in bulk packaging, with 1142 pieces currently in stock as new original inventory.
