## Description

Product Description The Bussmann series SL-15PK4 is a pack of 4 time-delay, rejection base plug fuses. The SL plug fuses are ideal for residential motor circuits in kitchens, workshops, garages and utility rooms. Plug fuses thread into receptacles. Two types of threaded fuses are available: Edison base (brass) and rejection base (porcelain). The two are not interchangeable. TL and SL medium-duty fuses are regular duty fuses. T and S are heavy duty fuses for more demanding applications with high inrush currents. Plug fuses provide a compact and economical method to prevent electric motor damage, reduce downtime and lower maintenance costs by opening when an overload is present. When used for residential branch circuit protection, fuses are typically located in the main fuse panel. From the Manufacturer SL fuse for residential motor circuits in kitchens, workshops, garages, utility rooms or any circuit with motors, relays or solenoids. The rejection base threads prevent a larger amp fuse from being used. Example: A 30 amp fuse cannot be installed in a 20 amp receptacle because of the different sized threads. Medium-duty fuse. These fuses thread into fuse receptacles. Threaded fuse type: Rejection Base (porcelain threads). Not interchangeable with Edison Base (brass threads) type. Medium-duty (SL) category plug fuse. The medium-duty fuse (SL) has a time-delay feature for use on motor circuits. Plug fuses are rated for a maximum of 125Vac. SL three pack (PK3) version (blister pack). Plug fuses are often used in residential and industrial branch circuit and motor protection. Fuses are used to protect furnace blower motors, pumps, power tools, garage door openers, etc. Motor protection fuses are usually used in conjunction with branch circuit protection. The fuse is often located in a box cover unit. Plug fuses provide a compact and inexpensive method to prevent damage to electrical motors. They help reduce downtime and lower maintenance costs by opening the circuit when a dangerous overload is present. When used for residential branch circuit protection, fuses are typically located in the main fuse panel.

Review: Works perfectly - Half the price of local hardware store.
Review: Handy and convinient for me - For the price it is worth buying. I use my cell phone several hours a day and my hands get tired and so it is nice being able to clamp the holder onto my coffee table while I sit on my sofa writing in my notebook and having both hands free. I also use it to clip onto my kitchen table, and even in bed I clamp it to a pillow so that I do not have to hold my phone. I have have clamped it a border fence while out gardening and to my deck while sitting outside. So for me it comes in very handy. The down side of using it it I would say is that the long adjustable arm is kind of hard to bend. It is similar to bending the arm of a gooseneck lamp, except it is stiffer and harder to bend. But that is good because it is strong and holds the weight of the cell phone very well. It is strong and well made. The two clamps, one on each end are also strong and secure. The bottom one that clamps to the table holds it very securily. And the top clamp hold the phone securily. If mine ever breaks I will be buying a new one. For the $7 it is certainly worth it.

Slow blow fuse works great used for window air conditioner. I choose fuses over breakers. Fuses never fail and don’t wear out.
