PRODUCT BENEFITS & APPLICATIONS
Arc-Flash Relay
Arc-Flash Relays protect your equipment and people while also reducing downtime in the case of an arc flash. The relay can detect a developing arc-flash incident and send a trip signal to interrupt power before significant damage occurs. Their simple plug-and-play installation make them the perfect, cost-effective solution.
Protect this equipment with an Arc-Flash Relay: ■ Chillers ■ Feeders ■ Grain silos ■ Refrigeration equipment ■ Transformers
Current Monitoring Relays
Current monitoring relays use current levels to determine feed rates, tool wear, loss of prime on pumps, mixer viscosity and all types of overload and underload conditions. They may also be used to stage pump motors, chillers and other machinery.
Monitor your: ■ Boilers ■ Chillers ■ Mixers
Feeder Protection
Feeder protection relays help protect circuits from overcurrent, ground faults, phase loss, overload and other detrimental conditions. Browse Littelfuse’s feeder protection relays below.
Protect this equipment: ■ Feeders ■ Grain silos
Ground-Fault Relays
Sensitive ground-fault relays quickly and reliably detect the breakdown of insulation resistance caused by moisture, vibration, chemicals or dust. With a wide variety of ground-fault relays, find the best one that meets your needs.
Littelfuse have ground-fault relays for your: ■ Chillers ■ Conveyers ■ Feeders ■ Grain silos ■ Heat exchangers ■ Process piping ■ Refrigeration equipment ■ Steam cooking■ UPS and power conditioning
Industrial Shock-Block GFCI
The Littelfuse Industrial Shock-Block SB6100 is vital where people, equipment, and water are present. This product is the first and only groundfault circuit interrupter (GFCI) to meet UL 943C Standard for People Protection. Additionally, it is the only GCFI device on the market that monitors the continuity of the ground circuit.
Use the Shock-Block with: ■ Conveyers ■ Drying equipment ■ Mixers ■ Process piping ■ Steam cooking
PRODUCT BENEFITS & APPLICATIONS
Motor & Pump Protection
Protect your motors and pumps from overloads, jams, phase loss or unbalance, heat, heavy startups or excessive operational cycles. From basic to advanced, Littelfuse offers a wide range of protection relays, intrinsically safe relays, liquid level controls, and load sensors to deliver the right protection for low-voltage applications.
Protect the motors in: ■ Chillers ■ Conveyers ■ Drying equipment ■ Grain silos ■ Mixers ■ Process piping
NGR & NGR Monitors
Neutral-grounding resistors work by limiting the fault current, so it does not cause unwanted fault damage, but still allows the protective relays to work. Browse their NGR monitoring products.
Use NGRs and NGR Monitors in: ■ Transformers
Timers
Delay starting and stopping loads, cycling, and sequencing of motors, pumps, compressors, heaters, and lighting.
Timers can be used in: ■ Boilers ■ Process piping
Voltage Monitors
Prevent damaged machinery and injury to personal by using voltage monitors. They prevent motors from running with no load applied and provide protection due to blown fuses, broken wires or worn contacts.
Protect your: ■ Boilers ■ Chillers ■ Conveyers ■ Drying equipment ■ Mixers ■ UPS and power conditioning ■ Process piping ■ Refrigeration equipment ■ Steam cooking
Surge Protection Device
With a globally-compliant, pluggable design, this easy-to-install and cost-effective SPD has higher nominal and total discharge current protection to help limit transient overvoltage to equipment mitigating costly damage and downtime.
Find the best surge protection device for: ■ Boilers ■ Chillers ■ Conveyers ■ Cooling towers ■ Drying equipment ■ Feeders ■ Heat exchangers ■ Mixers ■ Process piping ■ Refrigeration equipment ■ Steam cooking ■ Transformers ■ UPS and power conditioning
UL Class Fuses
Class CC, J, RK-1, RK-5, T, L and G
Littelfuse offers a variety of industrial power fuses to serve numerous applications in the food and beverage industry. Innovative features such as indication improve productivity while enhancing the safety of systems.
Midget Fuses
Midget style (10 x 38 size) fuses offer supplementary protection in a wide range of ampere ratings to match specific requirements while saving space.
Littelfuse can help you find the right fuse for all your equipment like: ■ Boilers ■ Chillers ■ Conveyers ■ Cooling towers ■ Drying equipment ■ Feeders ■ Heat exchangers ■ Mixers ■ Process piping ■ Refrigeration equipment ■ Steam cooking ■ Transformers ■ UPS and power conditioning
High-Speed Fuses
High-speed fuses protect critical power semiconductor devices against short circuits in applications including inverters, variable-speed drives, UPS and DC drive systems.
High-Speed Fuses can be used in: ■ UPS equipment
MROplus MATERIAL REDUCTION OPPORTUNITY PROGRAM
The Littelfuse exclusive MROplus program helps customers lower costs, increase plant safety, decrease downtime and reduce inventory. In this industrial fuse consolidation program, Littelfuse’s Technical Support Group analyzes a fuse inventory list and generates detailed reports to ensure the best circuit protection is being used. This decreases the risk of electrical hazards within your facility and saves time and money by optimizing inventory. All you have to do is complete a request form with your current fuse inventory and the MROplus program creates a custom recommendation for you. Best of all…it is absolutely free.
What can MROplus do for you?
Lower Costs
MROplus helps you upgrade circuit protection, increase safety, reduce fuse inventory, decrease downtime and improve productivity. These improvements amount to money saved towards your bottom line.
Improve Safety
Identify inadequate fuses and upgrade them to current-limiting circuit protection to reduce Hazard Risk Categories (HRC) in any type of facility. In accordance to NFPA 70E, after reducing HRC, workers are permitted to wear less Personal Protective Equipment (PPE) allowing repairs to be made quickly which minimizes time spent in live panels.
Decrease Downtime
Improve productivity with MROplus by converting to indicating fuses and consolidating inventory. Indication takes the guesswork out of fuse replacement with fast, visible identification, resulting in time and money saved.
Reduce Inventory
Eliminate duplicate or obsolete products and maintain only the fuses necessary for operation. This reduces SKUs, gets rid of waste and ensures the best protection available. Refer to the Fuse Consolidation Guide below to see how this is done.
HOW TO MITIGATE AN ARC FLASH
- 1 Use current-limiting fuses to reduce incident energy levels.
- 2 Use arc-flash relays to protect critical panels and detect an arc flash in milliseconds and trip the breaker.
- 3 Use high-resistance grounding (NGR) systems to improve the overall architecture of the electrical system and significantly reduce the opportunity for faults. Continuously monitor the neutral-to-ground path to verify the NGR is intact.
- 4 Stay out of the panel with the MP8000 Bluetooth relay
