Key Parameters

Substitute Part Grouping Explanation

Substitution of the SCHURTER 4420.0994 is determined by strict equivalence across the following parameters:

• Current Rating: 35A (exact match required)
• Voltage Rating - AC: 480V (exact match required)
• Mounting Type: DIN Rail (exact match required)
• Breaker Type: Thermal Magnetic (exact match required)
• Actuator Type: Lever (exact match required)
• Number of Poles: 3 (exact match required)

The E-T-A 4230-T130-K0CU-35A meets all mandatory substitution criteria. A variance exists in DC voltage rating (125V DC versus 65V DC on the original), which represents an upgrade in DC capability and does not restrict substitution in applications requiring 65V DC operation.

Parameter Comparison

Engineering Selection Recommendations

The E-T-A 4230-T130-K0CU-35A is a direct functional substitute for the obsolete SCHURTER 4420.0994. Both components share identical current, AC voltage, mounting, breaker type, actuation, and pole configuration. The E-T-A part carries active product status with current manufacturing support, ensuring availability for replacement and new installations.

The DC voltage rating differential (125V versus 65V) represents enhanced capability and poses no compatibility restriction for applications operating at or below 65V DC. Both parts maintain ROHS3 compliance and share overlapping regulatory approvals including CSA C22.2 No 235. The E-T-A component carries UL489 certification, appropriate for industrial circuit protection applications.

Frequently Asked Questions (FAQ)

Q: Can the E-T-A 4230-T130-K0CU-35A replace the SCHURTER 4420.0994 in existing installations?

A: Yes. Both components are three-pole, 35A, 480V AC thermal magnetic circuit breakers with lever actuation on DIN rail mounting. The higher DC voltage rating of the E-T-A part does not restrict operation in systems designed for 65V DC.

Q: What is the significance of the DC voltage rating difference?

A: The E-T-A part is rated for 125V DC compared to the SCHURTER part's 65V DC rating. This represents an upgrade in DC capability. Applications requiring 65V DC operation remain fully compatible.

Q: Are there packaging differences between these parts?

A: The SCHURTER part is packaged as individual units (indicated by "-" in packaging field). The E-T-A part is supplied in bulk packaging. Both are suitable for component-level integration into control systems.

Q: Do both parts meet the same regulatory standards?

A: Both parts are ROHS3 compliant and REACH unaffected. The SCHURTER part carries certifications including UL1077 and UL508. The E-T-A part carries UL489 certification. Both meet CSA C22.2 No 235 requirements for industrial circuit protection.

Q: Why is the SCHURTER part listed as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. The E-T-A 4230-T130-K0CU-35A maintains active product status with ongoing manufacturing support, making it the appropriate choice for new designs and long-term system maintenance.
