Motors | Automation | Energy | Transmission & Distribution | Coatings FSW Fuse-Switch-Disconnectors www.weg.net Fuse-Switch-Disconnectors The FSW Fuse-Switch-Disconnectors, developed according to International Standard IEC 60947-3 and bearing CE certification, are applied in electric circuits in general so as to provide the disconnection and protection against short circuits and overloads by means of NH blade contact fuses. In order to ensure a long lifespan, the FSW Fuse-Switch-Disconnectors are manufactured with reinforced thermoplastic materials and flame retardant. Additionaly, they feature contacts with silver coating, providing low power losses. Safety and Simplicity WEG switch-disconnector has several characteristics which aim at increasing security for operation and maintenance of the equipment, simplifying diagnoses and fuse replacement: g The switch-disconnector allows checking the state of the fuses through a transparent cover, besides featuring small openings which allow making electrical measurements without interrupting the operation. g As per IEC 60947-3, the switch-disconnector can perform the non- frequent opening under load. The FSW series has arc chambers for the extinction of the electric arc and disconnects all the phases together, ensuring full insulation between the load circuit and power supply. g In the opening of the switch-disconnector, the fuses remain fixed to the cover, preventing their drop or accidental contact between the energized parts. Furthermore, the cover is totally removable, allowing simple fuse replacement in a simple and safe area out of the electrical panel. g The switch-disconnectors also feature a built-in auxiliary contact in order to indicate when they are open or not properly closed. g As accessory, it is possible to mount terminal covers on the connecting terminals so as to reduce the risk of accidental contact with the power cables. Selection of the Switch-Disconnector The switch-disconnectors are manufactured to use as conductor element (link) the blade contact fuses with dimensions established by standard DIN 43620, NH-type fuse. The switch-disconnector model to be used is directly linked to the dimension of the used fuse. Therefore, first a fuse housing (NH000 up to NH3) must be selected in order to define which fuse-switch-disconnector will be used. Secondly, you must check if the switch-disconnector is capable to carry circuit rated current. The current values are presented on page 4 and the rated current of the load must be lower than or equal to the maximum current of the switch-disconnector. The rated current of the fuse can be higher than the rated current of the switch-disconnector due to criteria to fuse dimensioning.

Since time constants can be set by the ratio of capacitors, very accurate filter responses became possible using switched capacitor techniques Æ Mixed-Signal Design was born! Switched Capacitor Building Blocks • Capacitors: poly-poly, MiM, metal sandwich & finger caps • Switches: NMOS, PMOS, T-gate • Op Amps: at first all NMOS designs, now CMOS Non-Overlapping Clocks • Non-overlapping clocks are used to insure that one set of switches turns off before the next set turns on, so that charge only flows where intended. (“break before make”) • Note the notation used to indicate time based on clock periods: ... (n-1)T, (n-½)T, nT, (n+½)T, (n+1)T ..

    Printed Circuit Board Mount Switches Shock Proof • Waterproof • Explosion

    shock proof • waterproof • explosion proof Printed Circuit Board Mount Switches These versatile switches are a great choice for many applications due to their small size and variety of connection styles. Although these switches are built to connect to a printed circuit board, they can also be retrotted for nearly any application by connecting wire leads. These switches can sense a pressure ranging from 6 inches of water all the way up to 65 PSI. For a frame of reference, a trumpet player blows 55 inches of water (or 2 PSI) on average, so these switches have a broad range. They can also be used to sense a vacuum ranging between 6 inches of water to 65 inches of water. Therefore, these miniature single pole and double pole switches are used as pressure, vacuum, or dierential pressure switches where moderate accuracy is sucient. Presair switches deliver critical benefits: CSPSSGA - PC Mount Switch SAFE: Presair switches deliver complete electrical isolation with zero voltage at the actuator to shock the user or spark an explosion. 1”x1”x1.5” ECONOMICAL:Presair’s switching system costs are comparable or lower than digital controls meeting the needs of original equipment manufacturers. ACCURATE: All switches are 100% tested to meet 100,000+ cycle life. General Specification: RATING: 1 amp resistive 250 VAC Ratings are dependent on actuation pressure and must be derated at lower pressures. APPROVAL: UL Recognized, CUL Recognized. File #E80254 MATERIAL: Lower body: Rynite w/ pin terminals molded Upper body: Acetal Diaphram material is dependent on application. PRESSURE RANGE: When used as a pressure or vacuum switch the actuation point must be factory set.

  • Introduction How Circuit Protection Devices Work?

    Introduction How Circuit Protection Devices Work?

    Introduction Adding extra strain to any person or object can be a recipe for disaster. This is especially the case for electrical circuits. When they’re tasked with carrying more current than they were designed to handle, the added burden can lead to detrimental and dangerous circumstances. Not only could overloading your circuits damage or destroy your sensitive electronic equipment, but it could also generate extra heat in wires that weren’t meant to carry the load. If this happens, it can cause a fire in a matter of seconds. This is where an overcurrent protection device, such as a fused disconnect switch or a circuit breaker, comes in. Though they serve a similar purpose, these two components each have a unique design. Today, we’re sharing how they work and how to choose the right one for your project. Ready to learn more? Let’s dive in. How Circuit Protection Devices Work? The field of circuit protection technology is vast, designed to prevent circuits from risks associated with overvoltage, overcurrent, reverse-bias, electrostatic-discharge (ESD) and overtemperature events. Such risks include: • High-voltage transients • Capacitive coupling • Inductive kickback • Ground faults • High inrush currents From your smartphone battery to your steering wheel, these components are necessary to ensure safe and reliable electronics. While they all serve a valuable purpose, we’re delving deeper today into the specific field of overcurrent protection. Overcurrent protection devices are designed to disconnect or open a circuit quickly in the event that an overload or short-circuit occurs. This helps to mitigate any damage to the connected equipment and can also reduce the risk of electrical fires.
