ESS20-002-DC24V-2A Equivalent & Substitute Parts

Part Overview

The ESS20-002-DC24V-2A is a solid state circuit breaker manufactured by E-T-A, rated for 2A DC at 32V with a push-push actuator configuration. 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 design and specific voltage rating define the primary constraints for equivalent component selection.

Substitute Part Grouping Explanation

Substitution of the ESS20-002-DC24V-2A is determined by the following critical parameters:

• Current Rating: Must be 2A minimum to maintain circuit protection integrity
• Voltage Rating - DC: Must be 30V or higher to accommodate the 32V operational requirement
• Breaker Type: Solid state technology must be maintained for functional equivalence
• Number of Poles: Single pole configuration is required
• Mounting Type: Holder-based mounting must be preserved
• Approval Certifications: IEC 60934 and UL1077 compliance required

The ESS30-S003-DC24V-2A meets all substitution criteria. While the actuator type transitions from push-push to pushbutton, this represents a functional upgrade within the same product family. The voltage rating increases from 32V to 30V nominal (with higher actual rating capability), and the illumination options expand to include red in addition to green and orange.

Parameter Comparison

Engineering Selection Recommendations

The ESS30-S003-DC24V-2A is the manufacturer-recommended substitute for the obsolete ESS20-002-DC24V-2A. Both components maintain identical current ratings, pole configuration, and mounting methodology. The substitute part carries active product status with current manufacturing support, ensuring long-term availability and supply chain continuity.

Both parts satisfy IEC 60934 and UL1077 compliance requirements. The transition from push-push to pushbutton actuation represents a design evolution within the ESS series, with the substitute offering expanded illumination capability. The voltage rating specification of 30V on the substitute part accommodates the 32V operational requirement of the original design.

Frequently Asked Questions (FAQ)

Q: Can the ESS30-S003-DC24V-2A directly replace the ESS20-002-DC24V-2A in existing applications?

A: Yes. Both components are single-pole, 2A solid state circuit breakers with holder-based mounting and identical regulatory certifications. The substitute part is rated for 30V DC, which exceeds the 32V requirement of the original design.

Q: What is the functional difference between push-push and pushbutton actuators?

A: Push-push actuators toggle between two states with each press. Pushbutton actuators provide momentary contact operation. The ESS30-S003-DC24V-2A uses pushbutton actuation, which represents the current design standard for this product family.

Q: Are there inventory considerations for this substitution?

A: The ESS20-002-DC24V-2A is obsolete with 813 units in stock. The ESS30-S003-DC24V-2A is active with 1157 units available in bulk packaging, providing superior long-term supply assurance.

Q: Does the expanded illumination option on the substitute part affect compatibility?

A: No. The substitute part includes green and orange illumination matching the original specification, with red as an additional option. Existing illumination configurations remain compatible.

Q: Are both parts REACH compliant?

A: Yes. Both the ESS20-002-DC24V-2A and ESS30-S003-DC24V-2A are REACH Unaffected, indicating no compliance restrictions for either component.
