Range of Starters... for Every Need CITATION STARTERS

A Range of Starters BCH manufactures a wide range of motor starters to suit every application in the field. The capacity starts from fractional horse power to 2 hp completely assembled ready to use units with built in overload and single phasing protection. Mini Manual Starter (Upto Hp) DirectOnLine, manually operated, Mini Starter is designed for nonreversing control of all types of squirrel cage motors with an intermittent duty of 5 starts per hour (utilisation category AC3) complying with performance requirements of IS 8544 Part I. It is capable of switching motors upto HP, 45V, 3Phase or 3 HP single phase. The starter unit comprises of a double break, on load switch operated by means of a toggle link mechanism. Adjustable bimetable thermal overload trips are included which can be set to follow closely the heating characteristics of the motor.

Citation M Starters Contactor The contactors used in starters are NHD and Citation. They are built to IS 3947 and have many distinctive features such as : High grade moulding which reduces tracking and prolong operational life. Precision ground magnet frame and armature surfaces ensure consistent quiet operation. Exposed metals are treated for corrosion resistance. Low bounce and weld resistant contacts of silver cadmium oxide. Contactors can be inspected and maintained without disturbing adjacent wiring or altering contractor mounting positions. Coil is totally encapsulated in resin resisting moisture, corrosive atmosphere and damage while handling. Mechanical interlocking is provided between Star and Delta Contactors in case of Starter ratings 4HP and above. DOL UPTO 3 HP STAR DELTA UPTO 2 HP REVERSING DOL UPTO 2 HP Overload Relay Overload Protection : The relay fitted in the starter protects the motor from operational overload as per relevant standards established for the protection of motors. The range of current setting on any relay is between % to 6% of its minimum setting. Single Phasing Protection : The relay offers protection against single phasing through its sensitive differential mechanism in excess of the requirements of IS specification 39474 and trips when it carries in healthy phases.9 times the minimum current setting, regardless of the value to which the current adjustment lever is set. Full protection is provided on single phasing under varying operational up to % of the full load rating of the motor. No protection is required below this value. Protection against unbalanced voltage : The relay allows minor imbalance in voltage conditions in the three phases within the limits motors are designed to withstand. Beyond these limits, the relay trips and protects the motor. Excellent temperature compensation between C and +8 C (+55 C max. ambient). Facility for selection of either manual or automatic resetting of the trip switch. Snapon cover to prevent inadvertent alteration to the setting of current adjustment or to the hand/auto lever. Test facility for tripping relay manually for checking of the circuit and wiring. Automatic Time Delay Relay The Time Delay Relay used in Automatic Star Delta Starter has superb repeat accuracy, gives satisfactory performance in frequent starting applications. It resets fast and the timing is not affected by variation in ambient temperature and voltage.
