LP-CC-30 TIME DELAY FUSE BUSSMANN

LP-CC-30 TIME DELAY FUSE BUSSMANN – Industrial 30A 600VAC/300VDC Class CC Dual-Element Time-Delay Fuse

The LP-CC-30 TIME DELAY FUSE BUSSMANN (Model LP-CC-30) is a high-performance, ultimate-protection dual-element time-delay branch circuit fuse manufactured by Eaton’s Bussmann series. Engineered specifically to provide advanced overcurrent, short-circuit, and high-inrush protection for industrial motor circuits, control transformers, and power distribution systems, this $30text{-amp}$ , $600text{ VAC} / 300text{ VDC}$ Low-Peak™ Class CC fuse delivers maximum current limitation across compact automation panels.

Featuring dual-element time-delay performance, the LP-CC-30 TIME DELAY FUSE BUSSMANN holds a minimum $12text{-second}$ time delay at $200%$ of its rated current. This allows temporary motor starting currents, transformer magnetizing inrushes, and inductive coil transients to pass without causing unwanted fuse openings. Under severe short-circuit conditions, its fast current-limiting action safely interrupts prospective fault currents up to $200text{ kA RMS}$ Symmetrical at $600text{ VAC}$ and $20text{ kA}$ at $300text{ VDC}$ . Constructed in a compact $13/32'' times 1-1/2''$ ( $10.3 times 38.1text{ mm}$ ) melamine body format, it incorporates a physical Class CC rejection tip to prevent non-current-limiting fuses from being inserted into protected holders.

Key Features of the LP-CC-30 TIME DELAY FUSE BUSSMANN

Dual-Element Time-Delay Design: Holds a minimum $12text{-second}$ time-delay at $200%$ rated load, eliminating nuisance tripping caused by motor startup surges and inductive transients.
Class CC Rejection Feature: Built with a standardized rejection tip that pairs exclusively with UL Class CC fuse blocks, preventing accidental insertion of lower-rated or non-current-limiting fuses.
High $200text{ kA}$ Interrupting Capacity: Rated to safely interrupt short-circuit currents up to $200text{ kA RMS}$ Symmetrical at $600text{ VAC}$ ( $20text{ kA}$ at $300text{ VDC}$ ), ensuring compliance with NEC® Section 110.9 safety standards.
Extreme Current Limitation: Limits peak let-through thermal energy ( $I^2t$ ) and magnetic forces during short circuits, protecting downstream equipment and conductors from damage.
Dual AC/DC Voltage Rating: Operates continuously up to $600text{ VAC}$ and $300text{ VDC}$ , serving AC power systems and DC bus power circuits.
Type 2 “No Damage” Protection: Proper sizing can provide Type 2 coordinated short-circuit protection for NEMA and IEC motor controllers and contactors.

Common Applications and Practical Usage

The high breaking capacity, $30text{A}$ rating, and superior surge handling of the LP-CC-30 TIME DELAY FUSE BUSSMANN make it a protective device across industrial and commercial facilities:

Small Horsepower Motor Circuits: Provides compact branch-circuit protection and Type 2 “No Damage” protection for fractional and small AC motor branch circuits.
Control Transformer Primary Protection: Protects primary windings of industrial control transformers against short circuits while riding through heavy magnetizing inrush surges.
Solenoids, Contactors & Relays: Safeguards inductive control loads, electromagnetic valves, and contactor coils from sustained thermal overloads.
Industrial Control Panels & Branch Feeds: Ideal component for protecting low-amperage branch circuits, specialized equipment, and PLC output cards in $600text{V}$ machinery panels.

Operating Guidelines and Usage Tips

SAFETY NOTICE: Always isolate main power supplies and verify circuits are completely de-energized using a calibrated voltage tester prior to inspecting or replacing power fuses.

Holder Compatibility: Install exclusively in dedicated UL Class CC rejection fuse blocks or finger-safe DIN-rail modular holders (such as Bussmann CHCC series holders).

Motor Protection Sizing: For motor branch circuits, follow NEC® Article 430 rules, sizing the fuse between $150%$ and $175%$ of motor full-load current (FLA) to ensure complete protection without nuisance trips during motor startup.

To review official Class CC branch-circuit fuse standards and low-voltage current-limiting guidelines, consult the National Electrical Manufacturers Association (NEMA) Directory.
