Bussmann 170M4116 – Frequently Asked Questions

1) What does Class aR mean, and can I use this fuse as the only overcurrent protection on a circuit?
No, not on its own. aR stands for accompanied semiconductor protection, which means the 170M4116 handles short circuit protection for SCRs, diodes and power modules but is intended to work alongside another device that covers overload. If you need a fuse that protects across the full range including overload on a semiconductor circuit, you want a gR/gS type instead of an aR.
2) Is the Bussmann 170M4116 rated for a 690V drive, and can it be used on DC?
It is rated 690V AC, with the voltage type listed as AC, so a 690V AC drive or converter circuit is within rating. There is no DC rating stated for it, so do not apply it to a DC link or battery circuit on the strength of the AC number. Interrupting rating is 200 kAIC.
3) How do I check the 170M4116 will protect my SCR or diode module?
Compare the fuse I2t against the semiconductor's withstand I2t. The 170M4116 has a pre-arc I2t of 52,000 and a clearing I2t of 350,000 at 660V. The clearing figure must be lower than the I2t rating of the SCR or diode it sits in front of, otherwise the device lets go before the fuse does. Clearing loss is listed at 80.
4) Does the Bussmann 170M4116 have insulated metal gripping lugs for hot pulling?
No. IMGL is listed as No on the 170M4116, so it has bare bolted blade tags with no insulated grip. Isolate and lock out the disconnect before removing or fitting it.
5) Is this 630A Bussmann fuse CE marked for a machine being shipped to Europe?
Yes. The 170M4116 is CE marked and IEC rated, which is what a panel builder needs for a machine destined for the European market. It carries a 630A rating at 690V.
