Mersen Tri-Onic® TR125R Current Limiting Low Voltage Time Delay Fuse, 125 A, 250 V AC/DC, 200/20 kA Interrupt, RK5 Class, Cylindrical Body
Tri-Onic TR-R current-limiting time-delay fuses are engineered for overcurrent protection of motors, transformers, service entrance equipment, feeders and branch-circuits. The time-delay characteristics of the TR-R safely handle harmless starting currents and inrush currents associated with today's motors and transformers.

Size & Type: 5.25-ounce aerosol spray can. Formula: Technical fine-grade molybdenum disulfide (moly) and graphite in a penetrating liquid carrier. Temperature Range: Effective from -20°F to 750°F (-7°C to 537°C). Common Uses: Aviation maintenance, industrial MRO, tractor-trailers, motorcycles, bicycles, and weapons.
QO and QOB one, two and three pole thermal magnetic circuit breakers provide overcurrent protection and switching on ac and dc systems. These circuit breakers have an over center, trip free toggle mechanism with quick make, quick break action and positive handle indication. They also have VisiTrip trip indication, which provides a visual indication that the circuit breaker has tripped and interrupted the circuit. A full line of features and factory installed accessories are also available such as shunt trips, auxiliary switches and alarm switches. This 1 pole QO circuit breaker is rated at 30A at 120VAC. This unit provides 10kA breaking capacity and plug in mounting. This product includes a 6mA ground fault A with pigtail. QO circuit breakers are UL Listed under UL File E84967 and are CSA Certified under CSA Master Contract 153555.
SUPERCOTE 5/32" IN 50 LB Supercote hard facing specialty welding electrodes are excellent low cost rods for moderate abrasion and low impact application in all positions. It can be forged and provides a crack resistant weld. It features a smooth arc action and easy slag removal. Typical applications include surface buildup on new or worn machine parts of cast steel and manganese steel.
3/32" SUPER NICKEL CAST 55 PERCENT NICKEL SPECIALTY ROD Super Ni-Cast 55% nickel is the ultimate rod for all known grades of cast iron. Extra nickel content for crack resistant, machinable welds. Great for joining heavy or thin sections to steel. The computer controlled coating produces welds that represent the optimum balance between tensile strength and machinability. Typical applications include welding grades 30, 40 and 50 gray cast irons - all thicknesses in all positions.
