Bussmann SL-30PK4 Rejection Base Time Delay Plug Fuse, 30 A, 125 V AC, 10 kA Interrupt, Class: SL
These fuses thread into fuse receptacles. Two types of threaded fuses are available Edison base (brass threads) and rejection base (porcelain threads). The two are not interchangeable. Two categories of plug fuses are available. The medium duty fuses (TL or SL) have a time delay feature for use on motor circuits. The heavy duty fuses (T or S) are industrial strength products featuring the exclusive Cooper Bussmann dual element construction. This spring loaded design provides superior short circuit and overload protection. The T or S fuses have more time delay than the medium duty fuses in order to better protect motors and critical residential circuits. Plug fuses are rated for a maximum of 125 VAC. TL and SL four pack (PK4) versions priced per box. 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.

All Anvil Class 150 Malleable Iron Fittings conform to ASME B16.3 and unions conform to ASME B16.39. All elbows and tees 3/8 in (10 DN) and larger are 100% gas tested at a minimum of 100 PSI (6.9 bar).
Littelfuse® POWR-GARD® JLLS350 Current Limiting Fast Acting Fuse, 350 A, 600 V AC/300 V DC, 20/200 kA Interrupt, T Class, Cartridge Body
Space saving Class T fuses are the most compact fuses available in ratings above 30 A - less than one-third the size of comparable Class R fuses. When rated in accordance with the NEC, Class T fuses provide Fast Acting overload and short circuit protection for non-inductive circuits and equipment. Used in inductive circuits, the ampere rating of Class T fuses must be increased to prevent opening on inrush currents. In such instances, Class T fuses may provide only short circuit protection.
