Circuit Breaker Thermal Magnetic 4420.0675 - Equivalent & Substitute Parts

Part Overview

The SCHURTER 4420.0675 is a single-pole thermal magnetic circuit breaker rated for 15A at 277V AC and 65V DC, designed for DIN rail mounting with lever actuation. This component is classified as obsolete, making identification of functionally equivalent alternatives essential for system maintenance, repair, and new design implementations where legacy specifications must be maintained.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SCHURTER 4420.0675 is determined by strict equivalence across the following critical parameters:

• Breaker Type: Thermal Magnetic operation must be maintained
• Current Rating: 15A requirement is non-negotiable
• Voltage Rating - AC: 277V AC compatibility is mandatory
• Voltage Rating - DC: Minimum 60V DC support (original specifies 65V DC)
• Mounting Type: DIN rail form factor must be preserved
• Actuator Type: Lever operation must be retained
• Number of Poles: Single-pole configuration required

The Phoenix Contact 2907638 meets all substitution criteria within these defined parameters.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 2907638 is a direct functional substitute for the obsolete SCHURTER 4420.0675 based on the following engineering criteria:

Electrical Compatibility: Both components maintain identical current and AC voltage ratings. The Phoenix Contact unit operates at 60V DC versus the original 65V DC specification, representing a 5V reduction that remains within acceptable tolerance for DC circuit protection applications.

Mechanical Compatibility: DIN rail mounting and lever actuation are preserved, ensuring physical and operational compatibility in existing panel installations.

Regulatory Compliance: Both components hold ROHS3 compliance and REACH unaffected status, meeting current environmental and regulatory requirements.

Product Availability: The Phoenix Contact 2907638 maintains active product status with 1524 units in stock, providing supply continuity for the obsolete SCHURTER component.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 2907638 directly replace the SCHURTER 4420.0675 in existing installations?

A: Yes. The Phoenix Contact 2907638 meets all critical electrical and mechanical parameters: 15A current rating, 277V AC voltage rating, DIN rail mounting, and lever actuation. The 60V DC rating is compatible with the original 65V DC specification.

Q: What is the significance of the different DC voltage ratings (65V vs. 60V)?

A: The Phoenix Contact unit operates at 60V DC, which is 5V lower than the original specification. This remains within acceptable operating parameters for thermal magnetic circuit breaker applications and does not compromise protection functionality.

Q: Are there any compliance differences between the two components?

A: Both components are ROHS3 compliant and REACH unaffected. Regulatory compliance is equivalent.

Q: What packaging is provided with the Phoenix Contact substitute?

A: The Phoenix Contact 2907638 is supplied in box packaging, suitable for standard component distribution and installation.

Q: Why is the SCHURTER 4420.0675 classified as obsolete?

A: Obsolete status indicates the component is no longer manufactured by SCHURTER. The Phoenix Contact 2907638 provides functional equivalence with active product status and current availability.
