LP-CC-10 LOW PEAK BUSSMANN FUSE

LP-CC-10 LOW PEAK BUSSMANN FUSE – Industrial 10A 600VAC/150VDC Class CC Dual-Element Time-Delay Fuse

The LP-CC-10 LOW PEAK BUSSMANN FUSE (Model LP-CC-10) is an ultimate-protection, dual-element time-delay Class CC current-limiting power fuse manufactured by Eaton’s Bussmann series. Engineered specifically to provide high-level protection for motor branch circuits, control transformers, branch panelboards, and automated control cabinets, this 10-amp, 600 VAC / 150 VDC Low-Peak™ fuse delivers high-speed short-circuit interruption in a compact physical footprint.

Designed with an advanced dual-element time-delay mechanism, the LP-CC-10 LOW PEAK BUSSMANN FUSE provides a minimum 12-second time-delay at 200% of its rated current. This delayed response permits temporary, harmless magnetizing inrush currents from control transformers and starting surges from small motors to pass safely without nuisance tripping. However, under severe short-circuit conditions, its fast current-limiting operation interrupts high-energy fault currents up to 200 kA RMS Symmetrical at 600 VAC and 20 kA at 150 VDC. Built in a compact 10.3 x 38.1 mm (13/32” x 1-1/2”) rejection profile, it physically prevents non-current-limiting or lower-rated supplementary fuses from being inserted into protected circuits.

Key Features of the LP-CC-10 LOW PEAK BUSSMANN FUSE

• High 200kA Interrupting Capacity: Fully rated to interrupt high short-circuit currents up to 200 kA RMS Symmetrical at 600 VAC (and 20 kA at 150 VDC), fulfilling National Electrical Code (NEC®) Section 110.9 safety requirements.

• 12-Second Time-Delay Performance: Delivers a minimum 12-second time-delay at 200% rated load, absorbing temporary startup surges without premature opening.

• Class CC Rejection Feature: Built with a standardized Class CC rejection tip that physically keys into Class CC fuse blocks, preventing accidental over-fusing or substituting lower-rated fuses.

• Consistent 2:1 Selective Coordination: Simplifies selective coordination across Low-Peak™ distribution networks with a standard 2:1 ampacity ratio to avoid widespread power outages.

• Type 2 “No-Damage” Controller Protection: Proper sizing provides Type 2 “No-Damage” protection for NEMA and IEC motor controllers during short-circuit fault events.

• Durable Melamine Construction: Built with a high-density melamine tube casing that provides high arc-quenching capability and mechanical strength under high thermal loads.

Common Applications and Practical Usage

The high breaking capacity, surge tolerance, and space-saving profile of the LP-CC-10 LOW PEAK BUSSMANN FUSE make it a preferred choice across industrial panels and specialized machinery:

• Small Horsepower Motor Circuits: Serves as dedicated branch circuit protection for small AC motors, pumps, blowers, and motor controllers.

• Control Transformer Primaries: Safely handles heavy primary magnetizing inrush surges on industrial control transformers.

• Industrial Automation & Control Panels: Protects branch feeders, contactors, relays, and power supplies in 600V machine control cabinets.

• Solenoids & Inductive Loads: Prevents coil destruction and thermal overload in industrial solenoids, electromagnetic valves, and actuators.

Operating Guidelines and Usage Tips

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

• Holder Selection: Pair exclusively with dedicated UL Class CC rejection fuse blocks (such as Bussmann BCM series), finger-safe DIN-rail holders (such as Bussmann CHCC series), or panel-mount holders (such as HPS series).

• Inventory Consolidation: Because the LP-CC series combines time-delay performance with fast action under short circuits, upgrading to Low-Peak fuses can reduce spare fuse inventories by up to 33%.
