Featuring R-rated fuses and integrated overload relays, it provides advanced short-circuit and overload protection for medium voltage motors and controllers, complying with NEMA standards for rapid fuse response. Compact and reliable, it’s engineered to maximize motor uptime and safety in demanding industrial environments. ## Description 3-Phase Voltage/Phase Monitor 190 to 480VAC Torque: 12in-lbs; Wire: Stranded or solid “R” rated fuses provide required short-circuit protection for medium voltage motors, motor controllers and associated circuitry. These components have limited ability to absorb the energy of large short circuit currents. Medium voltage motor controllers contain overload relays which provide both overload protection and locked rotor protection to the motor. The controllers are also intended to interrupt low value short circuits within the capability of the motor controller. This protects the medium voltage fuse from sustained overcurrents which are less than their minimum interrupting rating. NEMA Standards for “R” rated medium voltage power fuses require that they operate within 15-35 seconds when subjected to an rms current 100 times the “R” rating. For example, a fuse with a 2R rating will open within 15 to 35 seconds on an applied current of 2 x 100 = 200 amperes. Live parts are available for mounting “E”, “R”, and “PT” single, double, and triple barrel fuses. Mounting clips are available for ferrule type and clip lock style fuses. All clips are sold in pairs.
