8 Thermal magnetic adjustments and characteristics Thermal adjustment Low voltage moulded case circuit breakers have a wide thermal adjustment range, one of the largest on the market. The rated current I r is continuously adjustable from 63% to 100% of this nominal current I n. There are three main points of calibration marked at 63%, 0% and 100%. Magnetic adjustment An adjustable magnetic characteristics allows short-circuit protection to be matched to the load and supply characteristics, for example motor inrush current or generator short-circuit current.

13 Microprocessor (electronic) based characteristics and adjustments EB2 series Etibreak 2 MCCBs from 250A to 1600A frame sizes are available with electronic protection units. Current ratings, In, of 40A, 125A, 160A, 250A, 400A, 6A, 00A, 1000A, 1250A and 1600A are available. These offer great flexibility as their characteristics can be set to suit a wide range of application conditions. Overload protection can be set between 0.4 and 1.0 times In. Selecting a Preset Characteristic for a 400A Etibreak 2 MCCB with Electronic Protection Every Etibreak electronic protection unit includes overload protection (L), delayed short-circuit protection (S) and instantaneous protection (I) as standard. Electronic protection characteristic Adjustment dials The left adjustment dial sets the rated current to match the conductor rating.

21 EB2R adjustments Residual current I D is the adjustable tripping threshold for earth leakage protection. It can be set between ma and 3A. Available settings are ma, 100mA, 0mA, 500mA, 1000mA and 00mA. Available settings are shown below Time delay t is introduced to the residual current (earth leakage) protection characteristic. Available settings are; INST, 60ms, 200ms, 400ms, 0ms and NT. INST means EB2R set to time delay 0 (max. actual tripping time is 40ms) NT means No trip (tripping time is O) The maximum breaking time is shown in brackets. Note that I n is set at ma, t defaults 0. I R is the adjustable tripping threshold for overload protection. It can be set between 0,63 and 1,0 times I n.

General purpose and heavy duty status indication switches cannot be mixed in the same MCCB. Only one alarm switch can be fitted to an MCCB. Shunt trips and undervoltage trips mount in the right side of the MCCB. It is not possible to install a shunt trip and an undervoltage trip in an MCCB as they occupy the same location. Undervoltage trips can provide remote tripping if necessary by wiring a normally closed contact or pushbutton in series with the protected supply. Undervoltage trips with time delays require an external time delay controller which clips to the side of the MCCB. Heavy Duty or Undervoltage Trip Shunt Trip 372

Ensure that the voltage does not drop exceeding the permissible voltage range when SHT is actuated. Breaker contacts usually start opening within ms after the rated voltage is applied to the breaker.

High-speed, stable actuation: The operating time as short as up to 0.1 second makes it possible to use the motor operators for synchronized closing of breakers. Silent operation: MO2S use a direct drive system, providing operational silence. Lock-in off capability: This capability allows the breaker to be padlocked in the OFF state. Up to thee padlocks with a 5 to mm hasp diameter can be used. Padlocks are not supplied. 391

Allow the longer time for the motor operator to complete the operation. 4*: The motor operator is of a short time duty. Do not subject it to more than 10 continuous ON-OFF operations. If this occurs, allow the motor operator to cool for at least 15 minutes. 5*: When the rated operational voltage is DC24V the open voltage will be DC22V. Motorized operation The motor operator has an input-signal self-hold circuit; closing the ON or OFF switch (see circuit diagrams shown bellow) momentarily allows activating the motor operator. To reset the tripped breaker to the OFF position, close the OFF (RESET) switch. The voltage presence LED indication is on when the power is supplied to the motor operator. Auto reset feature (optional) The auto reset feature allows the breaker to be automatically reset approx. 1.5 seconds after the breaker trips open. This option contains auto-reset switches and does not require to use auxiliary or alarm switches installed in the breaker. Note : that after the thermal OCR trips a thermal-magnetic breaker, the breaker cannot be immediately closed though it can be auto-reset. Wait for a few minutes after the tripping and provide a close signal to the breaker. This option resets the tripped breaker automatically, regardless of the cause of the tripping. Manual operation Pull the operating handle out. Rotating the handle counterclockwise turns ON the breaker and clockwise turns OFF or resets the breaker. Operation precautions 1. Ensure that the actual operation voltage ranges from 5% to 110% of the rated one. 2. Use operation switches whose ratings and power capacity is as specified in the Ratings and Specifications table on the previous page. 3. Use noise filters if the control power supply of the motor operator is shared by peripheral devices. Otherwise, power supply noise may cause malfunction of the peripheral devices. 4. When the motors are used in conjunction with the mechanical interlock the electrical interlock should be provided between the motors in order to avoid the simultaneous closing. The followings are the available electrical interlock cables. 392
