Applications & Selection Guide
The 170M1562D is engineered for semiconductor protection in industrial power electronics where conventional fuses are too slow to prevent device destruction. It is the correct choice for protecting IGBT modules, thyristor stacks, power diodes, and SCR assemblies in DC common bus architectures, variable frequency drives (VFDs), soft starters, and rectifier bridges operating on 690 V AC supply systems. The 32 A current rating makes it suitable for individual semiconductor device protection or sub-circuit protection within larger converter assemblies.
The Class gR rating distinguishes this fuse from general-purpose gG types — gR fuses are specifically characterised for semiconductor protection and operate in the sub-cycle timeframe needed to prevent junction damage in silicon devices. Panel builders in India specifying drives panels, renewable energy converter cabinets, or industrial motor control centres (MCCs) should confirm the fuse’s I²t let-through value aligns with the semiconductor device’s rated I²t withstand before final selection. Eaton’s Bussmann 170M Series documentation provides full time-current and I²t curves for coordination studies.
Industries across India that commonly deploy this fuse include steel and aluminium processing plants, textile machinery manufacturers in Coimbatore and Tiruppur, chemical process plants, wind and solar power inverter OEMs, and machine tool builders. The DIN 43620 knife blade format is widely supported by standard Bussmann fuse holders and DIN-rail mounted bases available in India, simplifying panel assembly and field replacement.

Frequently Asked Questions
What is the difference between a Class gR and a Class gG fuse for semiconductor protection?
Class gG fuses are general-purpose fuses designed for cable and overload protection with a relatively slow operating characteristic. Class gR fuses, such as the 170M1562D, are specifically engineered for semiconductor protection with a much faster operating characteristic and a lower I²t let-through value. This faster action is critical because silicon semiconductor devices like IGBTs and thyristors can be destroyed in a fraction of a cycle by a fault current that a gG fuse would still be clearing. Always use a Class gR or Class aR fuse when the equipment manufacturer’s documentation specifies semiconductor fuse protection.
What does the Dual Indicator (Type D) on the 170M1562D provide?
The Dual Indicator (Type D) provides two forms of blown-fuse indication simultaneously. The first is a visual indicator — a striker pin or flag that becomes visible when the fuse operates, allowing maintenance personnel to identify the blown fuse at a glance without a meter. The second is an electrical auxiliary contact output that can be wired into a PLC input, alarm relay, or drive interlock circuit to signal a fault condition remotely and prevent automatic restart until the fuse is replaced. This dual function significantly reduces fault-finding time in complex drive and converter panels.
Is the 170M1562D suitable for DC bus protection in VFD and converter panels?
Yes. The 170M1562D is explicitly rated and listed by Eaton for DC common bus and DC drive protection applications. When used on DC bus circuits, the applicable DC voltage rating must be confirmed from the Eaton Bussmann 170M Series datasheet for the specific circuit configuration, as DC voltage ratings differ from AC ratings. Consult the full product datasheet or contact Shansen Enterprises for application-specific guidance before installation in DC bus circuits.
What mounting format and fuse holder does the 170M1562D require?
The 170M1562D is built to DIN 43620 DIN 000 format with knife blade contacts. It requires a compatible DIN 000 fuse holder or base that accepts knife blade termination. Eaton Bussmann offers a range of 170M Series fuse holders designed for this format. Standard third-party DIN 43620 DIN 000 bases may also be compatible — verify bolt centre dimensions and contact blade dimensions against the fuse datasheet before use. Shansen Enterprises can advise on compatible holder options available in India.
Does the 170M1562D carry CE and RoHS compliance for export panel builds?
Yes. The Eaton Bussmann 170M1562D is CE Marked, confirming conformity with applicable European directives, and is RoHS Compliant, meaning it is manufactured without the restricted hazardous substances listed under the RoHS Directive. These compliances make the 170M1562D suitable for inclusion in panels and equipment destined for export to European and other markets with equivalent regulatory requirements.
