Key Parameters

Substitute Part Grouping Explanation

Substitution of the SCHURTER 4420.0155 is determined by the following critical parameters:

• Current Rating: 1A (must match exactly)
• Mounting Type: DIN Rail (must match exactly)
• Breaker Type: Thermal Magnetic (must match exactly)
• Actuator Type: Lever (must match exactly)
• Number of Poles: 2 (must match exactly)
• Voltage Rating - AC: Minimum 277V required
• Voltage Rating - DC: Minimum 65V required
• RoHS Compliance: ROHS3 Compliant (must match)

The identified substitute parts meet these core electrical and mechanical requirements while maintaining equivalent functionality for circuit protection applications.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts are active products with current manufacturing support, addressing the obsolescence status of the SCHURTER 4420.0155.

The E-T-A 2210-T220-K0F2-H231-1A maintains identical DC voltage rating (65V) while providing higher AC voltage capability (480V versus 277V). This part carries CSA C22.2 No 235, GB 17701, IEC 60934, and UL1077 approvals.

The Phoenix Contact 2907650 provides elevated voltage ratings for both AC (480V) and DC (125V) applications. This part is certified to ROHS3 standards and maintains the same current and pole configuration.

Both alternatives satisfy the core electrical and mechanical requirements of the original SCHURTER component while offering active product status and compliance certifications.

Frequently Asked Questions (FAQ)

Q: Can the E-T-A 2210-T220-K0F2-H231-1A directly replace the SCHURTER 4420.0155?

A: Yes. Both parts share identical current rating (1A), mounting type (DIN Rail), breaker type (Thermal Magnetic), actuator type (Lever), and pole configuration (2). The E-T-A part provides higher AC voltage capability (480V) while maintaining the same DC voltage rating (65V), making it suitable for applications requiring the original 277V AC / 65V DC specification.

Q: What is the voltage difference between the substitute parts?

A: The E-T-A 2210-T220-K0F2-H231-1A is rated 480V AC / 65V DC. The Phoenix Contact 2907650 is rated 480V AC / 125V DC. Both exceed the original SCHURTER specification of 277V AC / 65V DC.

Q: Are the substitute parts RoHS compliant?

A: Yes. Both the E-T-A 2210-T220-K0F2-H231-1A and Phoenix Contact 2907650 are ROHS3 compliant, matching the compliance status of the original SCHURTER 4420.0155.

Q: What packaging is available for the substitute parts?

A: The E-T-A 2210-T220-K0F2-H231-1A is supplied in Bulk packaging. The Phoenix Contact 2907650 is supplied in Box packaging.

Q: Do the substitute parts carry the same certifications as the original?

A: The E-T-A part carries CSA C22.2 No 235, GB 17701, IEC 60934, and UL1077 approvals. The Phoenix Contact part maintains ROHS3 compliance and REACH unaffected status. Both parts meet international safety standards applicable to thermal magnetic circuit breakers.
