1 Loadline Moulded Case Circuit Breakers The Dorman Smith Loadline MCCB range spans current ratings from 20A to 10A and is complemented by a comprehensive range of accessories. This technologically advanced range ensures that there are no problems caused by harmonics, DC applications and temperature rise. Discrimination issues are easily resolved by simple selection of the appropriate device. All devices comply with IEC 97-2 and EN 97-2 and are manufactured in compliance with ISO Wherever practicable, all escutcheons are of compatible dimensions to facilitate installation and improve aesthetic appearance of the finished assembly. To meet increasing market demands Dorman Smith have introduced the Y Frame Series of MCCBs, featuring high breaking capacities with the options of ground fault protection and electronic microprocessor control. This new electronic range features selectivity utilisation category B throughout, and includes a number of complementary thermal and magnetic, generator compatible and switch disconnector devices. In addition, the range offers the option of different temperature calibrations. Features Current ratings from 20A to 10A Selectivity utilisation category A & B Thermal and magnetic, generator compatible and switch disconnector devices Temperature calibration options Technologically advanced design Benefits High breaking capacities Ground fault protection Accurate microprocessor controlled Wide electronic characteristic adjustment Comprehensive range of accessories Selectivity Applications Generator protection L.V.

28 Loadline Y Frame Motorised Operation Positive Contact Indication Colour coding indicates the true position of the contacts clearly: ON (red), OFF (green), TRIP (white). Easy Maintenance Breaker mounting, removal, and even setting changes can be done without removing the motor operator. Manual ON/OFF The Breaker can be opened (OFF or RESET) and closed (ON) manually. Y2/Y3 Motor Actuator Fast Closing Operation Closing in ms or less. The closing time remains constant over repeated operations. Reference Notes Permissible operating voltage range as follows: AC rated, 5 to 110% of the rated voltage. Requires breaker s auxiliary switch (1b-contact). Time values at the rated operating voltage. Allow a longer time for the motor operator to complete the operation, at lower operating voltage. 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.

29 Loadline Y Frame Motorised Operation Off P1 alarm switch (a-contact) Alarm Switch Contact (Y6, Y7 & Y only) Motorised Operation Off Control When the off switch is closed, self-hold control relay (Y) is activated and motor (M) operates to charge the closing spring. The breaker changes to OFF status. Reset Control When the breaker is in TRIP status, closing the OFF switch activates self-hold control relay (Y) and starts motor (M). Motor (M) charges the closing spring and resets the breaker. Auto charge/discharge function This automatic charge/discharge function is necessary to prepare the closing mechanism for the next ON/OFF operation. Auto Reset A switch fitted in the breaker, can be used to induce recharging of the closing spring and automatically reset the MCCB. Connect the automatic reset circuit as shown below. It is recommended that a time delay of approximately 3 minutes is introduced to the automatic reset circuit for thermal magnetic MCCB's.

31 Loadline Y Frame Application Data Characteristic Adjustment Y Frame Electronic MCCB Legend LTD Long Time Delay STD Short Time Delay INST Instantaneous I 2 t RAMP Pick-up LED Test Port Application : Overload protection, True R.M.S. : Short circuit protection and selectivity : Short circuit protection, fast acting : Provides easier grading with downstream fuses : Lights on LTD overload, flashes on PTA pick-up : Facility for TNS-1 OCR checker for calibration checking Each part of the characteristic curve can be independently adjusted. This unique adjustability of Long Time Delay, Short Time Delay and Instantaneous enables the standard electronic MCCB to achieve more than 200,000 permutations of its time/current characteristic. Y Frame Rating Data This makes the Loadline Y Frame electronic range one of the most flexible on the market. The rated current of the electronic trip unit breaker is adjusted using two current multipliers, with 15 increments from 50% to 100%. l 0 Base Current is set by adjusting this selector switch. Example: 1000A(l n ) x 0. = 00A (l 0 ) Long Time Delay I 1 current is set by adjusting this selector as required. Example: 00A (I 0 ) x 0.9 = 720 (I 1 ) T 1 Time is set by adjusting the selector as required from 5 to seconds (T 1 ) Short Time Delay I 2 current is set by adjusting the selector. This multiplies the base current (I 0 ). Example: 00A (l 0 ) x 6 = 00A (I 2 ) T 2 Time is set by adjusting the selector as required from 0.1 to 0.3 seconds (T 2 ). I 2t Short Time Ramp Switch, when in the OFF position the Short Time Delay operates with a definite time characteristic. In the ON position, the characteristic alters to ramp to assist with discrimination. Instantaneous short-circuit protection I 3 current adjustment multiplies the base current (l 0 ). Example: 00A (l 0 ) x 12 = 90A (I 3 ). Ground Fault l G current adjustment is set against the CT current (l n ). Example: 1000A (I n ) x 0.1 = 100A (l G ) 9 T G Time adjustment delays the tripping time as required from 0.1 to 0. seconds (T G ) 31
