RECOMMENDED FUSE BLOCKS

L60030C series

L60060C series (for CCMR 35–60A)

Refer to Fuse Block section of this catalog for additional

information.

Compared to other UL Listed fuses, Class CC fuses are the

most current limiting, rating for rating. Because they are

physically compact, they provide this superior protection in a

fraction of the space required by other fuse classes. For

example, when 600V three-pole, 30 ampere Class R fuse

blocks are replaced by Littelfuse Class CC fuse blocks, panel

mounting space is reduced approximately 70%. This is

especially important when a panel contains many fuses to

protect multiple circuit components.

†Refer to the POWR-PRO^®section for additional information.

APPLICATIONS

.41"

Three Types of Class CC Fuses, Specifically Designed

to Protect Different Types of Components

1) Motor protection — CCMR series; dual-element, time-

delay fuses specifically designed to protect motor circuits

up to 40 HP**.

0-30A

(10.3 mm)

.125"

(3.2 mm)

.50"

(12.7 mm)

2) Small transformer protection (control power

transformers) — KLDR series, time-delay fuses designed

to withstand the high magnetizing inrush of transformers.

3) General purpose protection of equipment requiring

fast overload protection — KLKR series, fast-acting

fuses used for protection of equipment containing solid-

state devices or other electronic components requiring fast

response on overloads.

35-60A

SAFETY

ꢀ

200,000 A.I.R. — Reliable interruption of all overcurrents up

1.880 REF.

to 200,000 amperes.

ꢀ

Extremely current limiting — Reduces damage caused by

heating and magnetic effects of short-circuit currents . . .

stops damaging short-circuit currents faster than any

mechanical protective device.

SPACE SAVING

ꢀ

Class CC fuses are the smallest 600V, 200,000 A.I.R. fuses

approved for branch circuit protection.

ECONOMICAL

ꢀ

Current limiting design often permits use of readily avail-

able, less costly equipment.

specific motor sizing information
