Circuit Breaker Thermal Magnetic 30A 277V 65V (SCHURTER 4420.0995)

Part Overview

The SCHURTER 4420.0995 is a single-pole thermal magnetic circuit breaker rated for 30A at 277V AC and 65V DC, designed for DIN rail mounting with lever actuation. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing system maintenance and new installations where original stock is depleted or unavailable.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for thermal magnetic circuit breakers is determined by strict alignment of electrical and mechanical parameters. The critical parameters governing substitutability are:

• Current Rating: 30A (exact match required)
• Voltage Rating - AC: 277V (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: 1 (exact match required)

The Voltage Rating - DC parameter permits a tolerance range. The main part specifies 65V DC; substitute parts with 60V DC rating remain functionally compatible within standard industrial applications where DC voltage does not exceed the substitute's rating.

Two substitute parts meet these criteria:

1. Parametric Equivalent: SCHURTER 4420.0233 (same series AS168XAC1, identical electrical and mechanical specifications)
2. Similar Substitute: Phoenix Contact 2907575 (TMC 8 series, all critical parameters match; DC voltage rated at 60V)

Parameter Comparison

Engineering Selection Recommendations

SCHURTER 4420.0233 is the primary parametric equivalent. It shares identical electrical ratings, mechanical configuration, and series designation with the main part. Both components are obsolete; selection between them depends on inventory availability and packaging requirements (the main part uses standard packaging; the equivalent uses bulk packaging).

Phoenix Contact 2907575 is a functionally compatible substitute with active product status. This part maintains all critical electrical and mechanical parameters with a single variance: DC voltage rating of 60V versus the main part's 65V. This difference is acceptable in applications where the DC operating voltage does not exceed 60V. The active status of this component provides superior long-term availability compared to obsolete alternatives. All three parts maintain ROHS3 compliance and REACH unaffected status.

Frequently Asked Questions (FAQ)

Q: Can SCHURTER 4420.0233 be used as a direct replacement for SCHURTER 4420.0995?

A: Yes. Both parts are identical in electrical ratings (30A, 277V AC, 65V DC), mechanical configuration (DIN rail mount, lever actuator, single pole), and breaker type (thermal magnetic). The only difference is packaging format.

Q: Is Phoenix Contact 2907575 compatible with applications using the original SCHURTER part?

A: Yes, provided the DC operating voltage in the application does not exceed 60V. All other electrical and mechanical parameters are equivalent. The Phoenix Contact part offers the advantage of active product status.

Q: What is the significance of the DC voltage difference between the main part (65V) and the Phoenix Contact substitute (60V)?

A: The DC voltage rating indicates the maximum DC voltage the breaker can safely interrupt. A 60V rating is suitable for applications operating at or below 60V DC. If your application requires operation above 60V DC, the SCHURTER parts (rated 65V DC) are required.

Q: Why are the SCHURTER parts listed as obsolete?

A: Obsolete status indicates these parts are no longer manufactured. Existing inventory may be available through authorized distributors, but long-term availability is not guaranteed. The Phoenix Contact 2907575, with active status, represents a more sustainable long-term solution.

Q: Does packaging format affect electrical or mechanical performance?

A: No. Packaging format (standard versus bulk) does not affect component performance, electrical characteristics, or mechanical compatibility. Selection between packaging options depends on procurement quantity and storage requirements.
