Littelfuse 10/10/2018Ground faults can be dangerous. A short to ground in a solidly-grounded system creates large currents that can damage equipment and cause a shutdown. A ground fault can also create an arc flash, which can cause serious injury to nearby personnel as well as damage to equipment.
Littelfuse 10/9/2018Resistance grounding protects a system against transient overvoltages caused by intermittent ground faults and it provides a method to locate ground faults. (Transient overvoltages and inability to locate ground faults are the most common safety issues with ungrounded systems.)
Littelfuse 10/9/2018A relay can have several ways of communicating that a decision has been made. Typically the relay will operate a switch (relay contact) to indicate that an input has surpassed a setting, or the relay can provide notification through visual feedback such as a meter or LED.
Littelfuse 9/21/2018Littelfuse Enhanced Overload Relays monitor line-side voltages to prevent starting equipment while fault conditions exist! Unlike standard thermal overload relays, which only protect against load-side faults, SymCom's 777 family of enhanced overload relays also act as "smart sensors" for incoming power lines.
Littelfuse New Industrial Relays, High-Speed Fuses Selected as Finalists for 2017 Product of the Year
Littelfuse 9/13/2018Marking the third consecutive year Littelfuse products have been recognized in the program, the finalists qualified are: MP8000 Bluetooth Overload Relays, AF0100 Arc-Flash Relays and POWR-SPEED PSR High Speed Fuses.
Littelfuse 4/17/2018Power must be applied at all times. When the level in the tank rises to the normal level, the Lead Float Switch closes. Pump "A" is turned on via Pump "A" contactor, and will remain in this condition until the Lead Float Switch opens. When the Lead Float Switch opens, the ARP relay contacts transfer.
Littelfuse, Inc., the global leader in circuit protection, announces that the AF0500 Arc-Flash Relay is a finalist for Plant Engineering’s 2015 Product of the Year Awards honoring outstanding achievements in innovative products for manufacturing.
