Frequently Asked Questions (FAQ)

Q: Can the SCHURTER 7010.6300.47 be used as a direct replacement for the 7010.6300.37?

A: Yes. The 7010.6300.47 is electrically and mechanically identical to the 7010.6300.37 across all specified parameters, including current rating, voltage ratings, response time, breaking capacity, thermal characteristics, and physical dimensions. No circuit modifications are required.

Q: What is the difference between these two part numbers?

A: The primary difference is product status. The 7010.6300.37 is obsolete, while the 7010.6300.47 is active in production. The 7010.6300.47 additionally carries ROHS3 and REACH compliance certifications. All functional and electrical specifications are identical.

Q: Are the physical dimensions identical?

A: Yes. Both parts share the same cartridge, non-standard axial configuration with dimensions of 0.093" diameter by 0.315" length (2.36mm x 8.00mm). Through-hole mounting compatibility is identical.

Q: What is the melting I²t value, and why is it important?

A: The melting I²t value for both parts is 0.0014. This parameter defines the thermal energy required to melt the fuse element and is critical for circuit protection coordination. Identical I²t values ensure equivalent protection characteristics.

Q: Are there any compliance or regulatory differences?

A: The 7010.6300.47 is certified as ROHS3 Compliant and REACH Unaffected. These certifications support compliance with environmental and hazardous substance regulations. The original 7010.6300.37 does not specify these certifications.

Q: What is the breaking capacity, and how does it apply to circuit design?

A: The breaking capacity is 300 A at rated voltage (125 V AC/DC). This specification indicates the maximum fault current the fuse can safely interrupt without component failure or hazard. Both parts are identical in this parameter.

Q: Can these fuses be used in both AC and DC circuits?

A: Yes. Both the 7010.6300.37 and 7010.6300.47 are rated for 125 V AC and 125 V DC operation, supporting dual-voltage circuit applications.

Q: What is the operating temperature range?

A: Both parts operate across a temperature range of -55°C to 85°C, supporting applications in standard industrial and commercial environments.
