It can also be used as /OFF switch, except NRF and NRP series. Load Relay /Voltage The internal structure is identical to the current tripping protector, but the protective element has no time-delay function and the load circuit is cut off by the instantaneous tripping of the protector. Suitable for purposes, such as cutting off the power supply by using the alarm signal of the secondary circuit of the transformer. Load As the auxiliary contact operation is interlocked with the /OFF of the main contactor, circuit protector operation can be monitored by a lamp. The auxiliary contact can also be used to control auxiliary circuits. Load B Load A The alarm contact is electrically independent of the /OFF of the main contactor, but actuates when the protective element operates. Therefore, the alarm contact can be used with a lamp or buzzer to indicate trip operation and control alarm circuits. After the alarm contact has tripped, turn the lever to set the alarm contact. Load B Load A The dual coil circuit protector is provided with both a series trip (current trip) and relay trip (voltage trip). In the following example circuit, oil A (current coil) performs overload and short circuit protection, while oil B (voltage coil) serves to shut down the circuit when the alarm contact detects an abnormal condition.

Suited for motor loads that draw high inrush currents lasting for a rather long period of time. Suited for transformer and lamp loads that draw steep inrush currents. Select an appropriate circuit protector with a required delay curve and rated current in consideration of the characteristics of the circuit or equipment to be protected. When starting an inductive load, the inrush current reaches up to over ten times the rated current. Select the rated current to prevent tripping at starting current. 4 Example Solenoid rating Rated current: 0.7A Inrush current: 3A max. Inrush time: Approx.0. sec Time in sec 0.

NV ircuit Protectors Time Delay urve and Ambient Temperature NV circuit protectors employ an electromagnetic tripping system, where the rated current (trip current) is not affected by ambient temperatures. But the time delay may vary with the oil viscosity in the oil dash pot. Lower oil viscosity at higher temperatures results in a shorter delay, whereas at lower temperatures the delay will be longer. Temperature orrection urve The time delay curves on the preceding page are measured at 40. reference to the following curves, time delays can be corrected according to ambient temperature. Inertial Delay Inertial delay is designed not to trip on a non-repeating single pulse of 0 times the rated current (peak value) for a duration of 8 ms. In addition, circuit protectors equipped with inertial delay do not respond to high inrush currents caused by transformer or lamp loads, but perform the specified interruption on the subsequent overcurrents.

NH Series ircuit Protectors Time Delay urve and Ambient Temperature Since NH series circuit protectors employ an electromagnetic tripping system, the rated current (trip current) is not affected by ambient temperatures but the time delay varies with the oil viscosity in the oil dash pot. Lower oil viscosity at higher temperatures results in shorter delay, whereas at lower temperatures the delay will be prolonged. The time delay curves on the preceding are at 5. reference to these curves, time delays can be corrected.

Order multipoles from IDE. Recommended Soldering onditions Solder the main terminal at a temperature of 390 within 0 seconds using a 60W soldering iron. Solder the auxiliary/alarm terminal at a temperature of 350 within 3 seconds using a 60W soldering iron. (Sn-Ag-u lead-free solder is recommended.) When soldering, do not touch the circuit protector housing, auxiliary and alarm contacts with the soldering iron, and do not bend the terminals or pull the wires. heck your actual soldering conditions before soldering.

Therefore, when circuit protectors of a small rated current are used for a power-supply switch, voltage drop should be taken into consideration. Internal resistance also varies with time delay curves in spite of the same rated current, which should be also considered during installation.

Lower oil viscosity at higher temperatures results in shorter delay, whereas at lower temperatures the delay will be prolonged. The time delay curves on the preceding page are at 5. reference to these curves, time delays can be corrected.

When the circuit protector is used in a low-voltage circuit, voltage drop should be taken into consideration. Temperature orrection urve The rated current is based on an ambient temperature of 5. Since a thermal tripping method is employed, the rated current should be corrected according to the ambient temperature with reference to the curves shown below.

An excessive overcurrent may affect the bimetal characteristics or damage the internal mechanism.. After tripping, the NRF cannot be reset until the bimetal cools down. Allow the NRF at least 60 seconds before resetting. When the NRF is used at an ambient temperature higher than the reference temperature, resetting sometimes fails even after 60 seconds because it takes a long time to cool down the bimetal. 3. The NRF may not trip at an instantaneous overcurrent due to its principle. Recommended Soldering onditions Solder the main terminal at a temperature of 390 within 0 seconds using a 60W soldering iron. Solder the auxiliary/alarm terminal at a temperature of 350 within 3 seconds using a 60W soldering iron. (Sn-Ag-u lead-free solder is recommended.) When soldering, do 4. The NRF is shipped in the status. To confirm operation of the models without manual OFF mechanism, apply approximately 00% the rated current to trip the NRF. 5. When installing quick connect receptacles to the terminals, hold the NRF body and press it into the quick connect receptacles. 6. Unlike conventional switches, the models with manual OFF mechanism are not suited for frequent switching due to their construction. (Their mechanical life is 40 operations at minimum when switching at no load.) 7. The models with manual OFF mechanism should be operated without load. not touch the circuit protector housing, auxiliary and alarm contacts with the soldering iron, and do not bend the terminals or pull the wires. heck your actual soldering conditions before soldering. 58

NRP Series P Board ircuit Protectors Higher economic efficiency than a fuse SIL subminiature circuit protectors adopting I terminal arrangements, and mountable directly on P boards Simple construction and high performance applying a positive load reversing mechanism by IDE's original design Unlike fuses, the thermal trip mode (bimetal) eliminates erroneous interruption due to inrush currents. Rated current can be selected to meet the load. ircuits with high inrush currents can be protected against overloads (unlike fuses). Reusable 00 operations (tripping at 00% the rated current) with higher economic efficiency, and less maintenance than fuses. Available in slim and flat styles.
