• 1p-Transient-Surge-Absorber

    3PY-240

    Transient/Surge Absorber
    3-Phase, 4-Wire

    Transient/Surge Absorbers (TSAs) provide system designers with a cost effective method of protecting sensitive electrical and electronic equipment from damage caused by switching transients, coil and motor backlash, and near miss lightning strikes. There are 3 models available: single-phase (1P), 3-phase delta 3-wire (3PD), or 3-phase wye 4-wire (3PY). Each model is available to cover nominal AC voltages of 120, 208, 240 and 480. TSAs are designed using a ceramic and metal oxide technique which causes the resistance of the device to decrease abruptly if the rated voltage is exceeded. Voltage ranges are achieved by varying the types of oxide used in each model. Resistance changes are very fast, requiring less than 50 nanoseconds after the threshold voltage is exceeded. All models can repeatedly absorb in excess of 24,000 watt spikes without damage.

  • 410-Auto-Charged-Capacitor-Trip-Device

    410-120

    Auto-Charged Capacitor Trip Device
    120 VAC

    The Model 410 Auto-Charged Capacitor Trip Device is a high-speed capacitor-type circuit breaker tripping unit. It differs from the conventional capacitor trip device in that it has a self-contained standby power source, which is capable of maintaining full operating voltage for several days. This device is primarily for use with circuit breakers which require some form of AC power for their closing operation: i. e. , circuit breakers having either a stored energy closing mechanism with an AC-operated release coil, or an AC solenoid-operated closing mechanism. There are no field adjustments required. The Model 410 has a cover-actuated safety switch, which discharges the capacitor and disconnects the primary source when the cover is removed. The Model 410 can be tripped manually, or by means of a voltage-sensing or phase loss monitor. Versions are available for 120 VAC or 240 VAC operations.

  • 412-Automatic-Reverse-Controller

    412

    Automatic Reverse Controller

    The 412 Automatic Reverse Controller is a current sensor designed to detect jamming of sewage grinders and to initiate the reversing of the grinder. The controller allows the selection of up to five forward/reverse cycles, and provides for an alarm output, if the number of cycles is exceeded. The current loop inputs are designed for direct connection of 10 amps at 240 VAC, or 5 amps at 480 VAC (up to 2hp motors). For higher currents, a current transformer must be used (the CT secondaries are connected to the 5 amp terminals, regardless of voltage). A manual push-button is used to simulate an over current condition and to test the relay contacts and alarm. A current level adjustment is used to optimize the trip point setting. LED indicators show the running direction of the motor and the alarm condition.

  • 421-Over-Under-Motor-Load-Monitor

    421

    Over/Under Motor Load Monitor

    The Model 421 detects an overload or under-load condition on all types of running motors; conveyor motors, elevator motors, mixer motors, submersible pumps, suction pumps, etc. The monitor detects the actual power used (voltage x current x power factor) and is more sensitive than simple current monitors. The Model 421 can be used with single-phase motors, or using the Model 276C Current Transducer, with three-phase motors. Matching CTs allow the Model 421 to be used with virtually any size of motor. Trip and restart delays are provided; one or both can be turned on or off.

  • 64-5-Power-Factor-Regulator

    64-5

    Power Factor Regulator

    The Model 64-5 Power Factor Regulator is a monitoring and power factor control system. It is designed to help obtain an improved power factor, with a minimum of added capacitors. This device uses a unique phase-angle sensing circuit to monitor the power factor of a 3-phase power line. The Model 64-5 automatically responds to changing power factor by closing or opening the internal relays, which add or subtract capacitor banks on the line. Although intended for 115VAC 60Hz systems, other voltage or frequency models may be available.
