Applications

These fuses are ideal for protecting lighting, heating, and other circuits that are not subject to temporary surges. They are suitable for use in industrial facilities, factory settings, and safety and security systems where available short-circuit currents are relatively low.

Standards and Certifications

• CE Certified
• UL Listed: Class K5 (1/8-60A), Standard 248-9; Class H (65-600A), Standard 248-6
• CSA Certified: Class 1421-01, File 53787

Ensure proper sizing and application in accordance with the National Electrical Code (NEC) guidelines. For motor circuits, size at 300% to 400% according to NEC motor ampacity tables 430.247, 430.250, and 430.6(A)(1).

Note: One-time fuses do not have any appreciable degree of time delay and should not be specified in circuits where large transients or motor overloads occur. For such applications, consider using time-delay fuses.
