Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SCHURTER 4420.0433 are identified based on the following critical parameters that determine functional equivalence:

• Current Rating: 6A (exact match required)
• Breaker Type: Thermal Magnetic (exact match required)
• Mounting Type: DIN Rail (exact match required)
• Actuator Type: Lever (exact match required)
• Number of Poles: 3 (exact match required)

The substitute parts listed below meet these core electrical and mechanical specifications. Voltage ratings differ from the original part; however, both substitute options provide higher voltage ratings that encompass the original specifications within their operational ranges.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts are active products with current manufacturer support, addressing the obsolescence of the original SCHURTER component.

Phoenix Contact 2907612 (TMC 8 Series) is ROHS3 compliant and REACH affected. This part provides higher voltage ratings (480V AC, 125V DC) and is available in active production status with 1041 units in stock.

Carlo Gavazzi GSB633PC6 (GSB63 Series) carries UL1077 approval and is ROHS3 compliant status not specified in available data. This part also provides 480V AC rating and is available in active production status with 850 units in stock.

Both parts satisfy the core functional requirements of the obsolete SCHURTER 4420.0433 based on matching current rating, breaker type, mounting configuration, actuation method, and pole count.

Frequently Asked Questions (FAQ)

Q: Can Phoenix Contact 2907612 directly replace SCHURTER 4420.0433? A: Yes. Both parts share identical current rating (6A), breaker type (thermal magnetic), mounting type (DIN Rail), actuator type (lever), and pole count (3). The Phoenix Contact part has higher voltage ratings, which are compatible with the original application parameters.

Q: Can Carlo Gavazzi GSB633PC6 directly replace SCHURTER 4420.0433? A: Yes. Both parts share identical current rating (6A), breaker type (thermal magnetic), mounting type (DIN Rail), actuator type (lever), and pole count (3). The Carlo Gavazzi part has higher AC voltage rating (480V), which is compatible with the original application parameters.

Q: What is the difference between the two substitute options? A: Phoenix Contact 2907612 specifies both AC (480V) and DC (125V) voltage ratings with REACH affected status. Carlo Gavazzi GSB633PC6 specifies AC voltage rating (480V) with UL1077 approval. Both are active products with comparable inventory availability.

Q: Why do the substitute parts have higher voltage ratings than the original? A: Higher voltage ratings indicate the parts are rated for operation across a broader range of applications. A part rated for 480V AC can operate safely at 277V AC. This does not affect compatibility or performance in the original application.

Q: Are there packaging differences between these parts? A: Phoenix Contact 2907612 and Carlo Gavazzi GSB633PC6 are both supplied in box packaging. Verify packaging requirements for your specific procurement and installation procedures.
