Bussmann KTK-R-2 Limitron Class CC Fast-Acting Fuse, 2A, 600V AC

The Bussmann KTK-R-2 is a Limitron series single-element, fast-acting Class CC fuse engineered for reliable current-limiting overcurrent protection. Rated 2-Amp at 600-Volt AC, this fuse features a rejection-style body that fits only Class CC fuse holders, helping prevent misapplication of non-Class CC fuses in the field. Its single-element, fast-acting, current-limiting construction is built to clear overcurrent conditions quickly, supporting dependable protection for branch circuits, motor control circuits, and connected equipment.

Key Features

  • Amperage Rating: 2-Amp rating suited for branch circuit and equipment overcurrent protection.
  • Voltage Rating: 600-Volt AC rating for use across a wide range of commercial and industrial circuits.
  • Class CC Rejection Style: Rejection-style body fits Class CC fuse holders and blocks only, preventing installation of non-Class CC fuses.
  • Single Element Design: Single-element construction provides straightforward, dependable overcurrent interruption.
  • Fast-Acting Response: Fast-acting time-current characteristic clears overcurrents quickly to help protect connected equipment.
  • Current-Limiting Performance: Current-limiting design helps reduce let-through energy during fault conditions.
  • Limitron Series: Part of the Bussmann Limitron family of current-limiting, fast-acting fuses.

Bussmann KTK-R-2 – Frequently Asked Questions

1) Will the Bussmann KTK-R-2 fit a standard Class CC fuse holder?
Yes. The KTK-R-2 is built as a Class CC rejection-style fuse, so it drops into Class CC holders and blocks. The same rejection body is what keeps it out of non-Class CC holders, and keeps someone from putting a non-CC fuse into your CC-rated equipment later.
2) Can I use a 2A KTK-R-2 on a 480V or 240V control circuit?
Yes. The KTK-R-2 is rated 600V AC, and a fuse may be applied at or below its voltage rating, so 480V and 240V control circuits are both within rating. The ampere rating is 2A, so it is sized for small control transformers, motor control circuits and similar light branch loads.
3) Fast-acting or time-delay Class CC fuse for a motor control panel?
The KTK-R-2 is the fast-acting one. Single-element, fast-acting fuses clear overcurrents quickly, which suits control circuits, electronics and other loads with no real inrush. If the circuit feeds something with an inrush surge, like a motor across the line or a control transformer that kicks hard on energization, a fast-acting 2A fuse will open on the surge and you want a time-delay Class CC instead.
4) What is the exact part number to order for the 2 amp Limitron Class CC fuse?
Order Bussmann KTK-R-2. That is the manufacturer part number for the 2A, 600V AC Limitron Class CC fast-acting fuse. The R in the designation is the rejection-style body.
5) Does a current-limiting fuse matter for my panel, or is any 2A fuse fine?
It matters. The KTK-R-2 is current-limiting, which means it reduces the let-through energy during a fault rather than just eventually opening. If your panel or equipment is marked for Class CC current-limiting protection, or the drawing calls for it as part of a short circuit current rating, a non-current-limiting 2A fuse is not an equivalent substitute.
6) I need the same fuse in a different amp rating. Does KTK-R come in other sizes?
Yes. KTK-R is a Bussmann series, and the number after the dash is the ampere rating, so KTK-R-2 is the 2A member of it. If your holder is Class CC and you need a different size, order the KTK-R in the amperage your circuit calls for; the 600V AC rating and fast-acting, rejection-style construction stay the same across the series.
7) Where is a 2A KTK-R-2 typically used in a commercial or industrial installation?
Typical spots are branch circuit overcurrent protection, motor control circuits and control panels, panelboards and load centers, and any equipment built around Class CC rejection-style holders. At 2A it is a control and small-load fuse rather than a feeder device.
