AFCI/GFCI/RCD插座和断路器

GFCI outlets, AFCI outlets, and RCD breakers keep the lights on. This block diagram shows Littelfuse components that help the required safety devices break circuits when overcurrents, arc flashes, or residual currents occur. In addition to thyristors that serve as silicon-controlled rectifiers for trip circuits, we make metal oxide varistors and TVS diodes to protect circuits from voltage surges.

Intelligent outlets let building managers and homeowners control energy use and costs via smartphones, tablets, or voice assistants. A block diagram shows which Littelfuse products help smart outlets operate as designed. Our TVS diode arrays and polymer ESD suppressors keep noise out of wireless signals. In addition, our Schottky diode rectifiers ensure circuits receive the dc power they require.

Industrial, outdoor, and residential LED lighting systems need different arrangements of electronic components. Block diagrams show how Littelfuse provides solutions for each system. Options include transient voltage surge suppressors and lightning protection devices designed just for LED lights, as well as ac LED drivers with solid state switches for rectification and power factor correction.

Smoke detector with smoke

烟雾和热量探测器

Wired smoke detectors and heat alarms require dependable ac power supplies, highly efficient dc-dc converters, and accurate temperature sensors. Littelfuse provides all of these electronic components, as well as a range of fuses for overcurrent protection and metal oxide varistors and TVS diodes for overvoltage protection.

SPD 1-2

SPD类型1和2

Boost safety and control building electrical systems by deploying smoke and heat detector, smart outlet, and LED lighting solutions from Littelfuse. We make sensors, relays for alarms, dimmers, and Type 1 and Type 2 SPDs to protect systems from lightning strikes. We also produce parts for AFCI, GFCI, and RCD outlets to prevent arc flashes and shocks.

White USB Outlet

USB outlets simplify and speed up portable electronic device charging. This block diagram highlights electronic components Littelfuse can supply for this next generation of USB chargers. Our solutions include Schottky diodes and MOSFETs with gate drivers to handle current rectification and ac-dc power conversion. We also offer NTC thermistors to protect battery units.

电路保护

Littelfuse UL fuses protect electrical systems from overload and short circuit. 选择Littelfuse保险丝而不是断路器是因为它们具有更高的安培数、更快的响应时间、易于协调且无需校准。 了解更多

Pre-engineered coordination panels provide a complete solution for easy procurement and code compliance in commercial buildings. Shunt trip POWR-Switches meet ANSI/ASME standards and work with fire safety systems. 了解更多

Shock Protection for Commercial Buildings

In buildings with commercial kitchens or structures like automotive garages with portable equipment, the NEC requires using a GFCI on 208 V three-phase equipment up to 100 A. Its use on this equipment will protect your employees from electric shock and ensure code compliance. 了解更多

Protect Critical Power Systems from Arc-Flash

Switchgear is the lifeline to supply power for critical systems in buildings such as hospitals and datacenters. Dependable protection from arc-flash events is critical to improve reliability of the power supply and prevent personnel injury and equipment damage. 了解更多
