Bussmann CGL Class C Non-Indicating Current-Limiting Fuse, HRC Form II

The Bussmann CGL Class C Non-Indicating Current-Limiting Fuse is part of the Eaton Bussmann series Tron CGL line, engineered to deliver dependable overcurrent protection for demanding electrical systems. Rated 600 Vac and 250 Vdc, this Class C, HRC Form II fuse offers a high interrupting capacity of 200 kAIC at 600 Vac and 40 kAIC at 250 Vdc, making it well suited to protecting circuits against damaging short-circuit currents. This is a family listing available in 24 selectable amp ratings from 3A through 600A, letting you match the exact current rating your application requires while standardizing on one proven current-limiting fuse platform. Its X blade-end terminals and non-indicating design support straightforward installation in compatible fuse holders and disconnect switches.

Key Features

  • Amp Rating Range: Available in 24 amp ratings from 3A up to 600A (3A, 4A, 6A, 10A, 15A, 25A, 40A, 45A, 50A, 60A, 80A, 90A, 110A, 125A, 150A, 175A, 200A, 225A, 250A, 300A, 350A, 400A, 450A, 600A), covering a wide span of branch-circuit and feeder protection needs.
  • Voltage Rating: Rated 600 Vac and 250 Vdc for use across both AC and DC electrical systems.
  • High Interrupting Capacity: 200 kAIC at 600 Vac and 40 kAIC at 250 Vdc deliver dependable protection in high-fault-current environments.
  • Current-Limiting Operation: Current-limiting design restricts let-through energy to help protect downstream conductors and equipment.
  • HRC Form II Construction: Built to HRC (High Rupturing Capacity) Form II standards for consistent, code-compliant fuse performance.
  • Class C Fuse: Class C classification provides standardized dimensional and performance characteristics.
  • X Blade-End Terminals: Blade end X terminal configuration for compatibility with corresponding fuse holders and disconnect switches.
  • Non-Indicating Design: Non-indicating construction (no blown-fuse indicator) keeps the fuse body simple and compact.

Bussmann CGL-3 – Frequently Asked Questions

1) Will a Bussmann CGL Class C fuse fit my existing fuse holder?
The CGL uses X blade-end terminals, so it drops into holders and disconnect switches prepped for a Class C, X blade-end fuse. Class C is a standardized dimensional class, meaning the body and blade geometry are fixed by the class rather than by the manufacturer, so a holder built for Class C X blade takes it. If your existing holder is a ferrule or bolt-on style, or a different blade end, the CGL is the wrong body for it.
2) Can I use the Bussmann CGL fuse on a DC circuit?
Yes, it carries a dual rating: 600 Vac and 250 Vdc. On DC the interrupting capacity is 40 kAIC, against 200 kAIC on the AC side. That DC rating caps it at 250 volts, so battery banks, DC drives and control buses above 250 Vdc need a different fuse. Available fault current on the DC side has to be under 40 kA.
3) Is the Bussmann CGL rated for a high fault current service?
200 kAIC at 600 Vac. That covers essentially any commercial or industrial service where the available fault current has been calculated, including large switchboards close to the transformer. It is also current-limiting, so it clips the let-through energy during a fault rather than just clearing it, which is what lets downstream conductors and gear be protected on a high-fault bus.
4) Does the CGL fuse have a blown-fuse indicator?
No. The CGL is non-indicating, so there is no pop-up pin or visual flag to tell you which one opened. On a three-phase feeder that means metering or continuity testing to find the failed leg. If your maintenance crew relies on a visual indication to troubleshoot without pulling fuses, specify an indicating fuse instead.
5) What does HRC Form II mean on a Bussmann CGL fuse, and does it matter for my panel?
HRC stands for High Rupturing Capacity, and Form II is the North American Class C body style with blade ends. It is the dimensional and performance standard the fuse is built to, and it is what your fuse holder or switch has to be listed for. If a drawing or an existing switch calls out HRC Form II Class C, the CGL matches. HRC Form I is a different body and will not interchange.
6) Can I standardize all my industrial panels on one fuse family with the CGL?
That is the practical case for it. One platform covers 3A control circuits through 600A feeders across 24 ratings, all on the same Class C X blade-end body and the same 600 Vac / 250 Vdc rating. For an MRO stockroom that means one shelf position style, one holder type, and part numbers that track the amp rating directly (CGL-15, CGL-60, CGL-400). The gaps in the ladder are the only thing to watch when matching an existing fuse.
7) Is a Class C fuse the same as a Class J or Class R fuse?
No, and they do not interchange. Class C is its own dimensional standard with blade ends, here in the X configuration on HRC Form II construction. Class J and Class R fuses have different body dimensions and rejection features, so a Class J holder will not accept a Class C fuse and vice versa. Match the class marked on your existing fuse or holder, not just the amp and voltage rating.
8) Will the Bussmann CGL work for motor branch circuit protection?
It is used for industrial motor and control circuit protection, along with panelboard and switchboard overcurrent protection, feeder and branch circuit fault protection, and OEM control panels. Sizing for a motor circuit depends on whether you need the fuse to ride through starting inrush, so size it against the motor nameplate and the applicable code rules for the protection type your drawing calls for.
9) How do I order the right Bussmann CGL fuse?
One thing to pick: the amp rating. The part number is CGL plus the amps, so the 3A is CGL-3, the 125A is CGL-125 and the 250A is CGL-250. Voltage, class, blade end and indicator style are fixed across the family at 600 Vac / 250 Vdc, Class C, X blade, non-indicating. Packaging is standard.
