Substitute Part Grouping Explanation

Substitution eligibility for thermal circuit breakers is determined by strict equivalence across electrical and mechanical parameters. The SCHURTER 4430.156 accepts substitutes that match all of the following criteria:

• Current Rating: 16A
• Voltage Rating - AC: 240V
• Voltage Rating - DC: 60V
• Breaker Type: Thermal
• Mounting Type: Panel Mount
• Actuator Type: Rocker
• Number of Poles: 2
• Illumination: Orange
• Illumination Voltage (Nominal): 220V
• Series: TA45

Only parts meeting these exact specifications are functionally equivalent and can be used interchangeably in the same circuit protection application.

Parameter Comparison

Engineering Selection Recommendations

Both the SCHURTER 4430.156 and 4430.1393 are active products with identical electrical and mechanical specifications. Both parts comply with ROHS3 requirements and REACH regulations, ensuring regulatory compliance in current manufacturing and procurement environments. Selection between these parts may be based on inventory availability and lead time considerations, as both are functionally interchangeable for 16A thermal circuit protection at 240V AC and 60V DC.

Frequently Asked Questions (FAQ)

Q: Can the 4430.1393 be used as a direct replacement for the 4430.156?

A: Yes. Both parts are identical in all critical parameters: 16A current rating, 240V AC and 60V DC voltage ratings, thermal breaker type, panel mount configuration, rocker actuator, 2-pole design, and orange illumination at 220V nominal. They are functionally equivalent and interchangeable.

Q: What parameters must match for a substitute circuit breaker to be acceptable?

A: Current rating, AC voltage rating, DC voltage rating, breaker type, mounting type, actuator type, number of poles, and illumination specifications must all match exactly. Any deviation in these parameters results in incompatibility.

Q: Are there any compliance differences between these parts?

A: No. Both parts carry identical RoHS3 compliance status and REACH unaffected designation, meeting current regulatory requirements for industrial electrical components.

Q: What is the inventory status for these substitute parts?

A: The 4430.156 has 907 pieces in stock, while the 4430.1393 has 1093 pieces in stock, both available as new original components in bulk packaging.
