• Cable boxes for paper insulated cables, fully interlocked isolator and ammeter can also be provided, on request

Rotor Controller:

• Is designed to comply with latest IS for use in Rotor Circuit of A.C. Slipring Motor
• Adequately rated resistance wires are selected as per the current at various steps and are robust in design
• The Rotor resistance is based on the Rotor Volts and Rotor Amps of the Motor
• The cutting off resistances are achieved by the rotation of CAM operated "wheel" and this provides smooth starting of the motor.

Special Features:

Foolproof interlocks are provided in the Starter as per the following :

• The Motor can be started only when full Rotor resistance is in the Rotor Circuit. Otherwise the Stator controlling OCB will not close.
• The motor cannot be left running with rotor resistance in the circuit. If by any chance the rotor resistance is left in the circuit the starter will trip no sooner the push button on the rotor controller is released.

Backed by years of experience and industry knowledge, S. M. Engineers today is recognized manufacturers, suppliers in India of top qualityautomatic air break star delta starterstype CSD/A for starting of squirrel cage induction motors. These comply to BSS 775 and BSS 587 and are suitable for 40 starts per hour. The product is offered at reasonable prices. They are manufactured at our manufacturing facility in Delhi which have all the latest equipment and machinery managed by a team of experts in the electrical field. All our products are known for their seamless performance, durability, customization and integrity even in toughest conditions.

Construction Air Brake Star Delta Starters

• Totally enclosed, in a deep-drawn sheet metal casing, wall mounting type, suitably gasketted to make it dust proof
• The entire starter assembly (which is mounted on a steel plate) can be taken out of the casing by removing four screws only.
• Maintenance is facilitated by taking the interior out for repair while a spare interior can be inserted.

Rating:

• The automatic star delta starters are ideal for controlling motors upto 40 HP at 400/440 volts or 500/550 volts
• Adjustable Timer is incorporated for automatic changeover from Star to Delta.

Protection:

• Are provided with magnetic type overload releases with an adjustable oil dashpot time lag device on all the three phases
• The magnetic overload device, which works on the magnetic principle of current, is totally independent of the ambient temperature, provides a positive and direct protection to the motor
• Non-aging properties inherent to the magnetic overload device ensures the same protection to the motor even after years of service
• Can also be fitted with thermal type bi-metallic overload releases with temperature compensation devices
• The overload device is of the Hand-Resetting type which is an essential feature where remote control is required.
• The under voltage protection is inherent

Control:

• Start and Stop/Reset Push Buttons are provided on the front cover
• Remote control terminals are also provided for remote operation by means of limit switch, float switch, pressure switch or a separate push button unit.

Isolator:

• A rotary type triple pole air break isolating switch can be provided on starters, the operation of which is interlocked with the lid of the starter
• Ensures that the starter lid cannot be opened till the isolator is in the OFF position.

Cable arrangements:

• Units are provided with entries for conduit connections
• Sealing boxes can be provided for underground paper-insulated cables.

Earthing:

• Double earthing terminals are provided.

Timer:

• Special current activated change-over Timer ensures transition from Star to Delta at approximately the rated current of the motor only, irrespective of the transition time which depends on the drive
• This leads to no wear on the contacts due to transition kicks.

Specifications of Liquid Rotor Starter

• The liquid Rotor Starter is manufactured confirming to BS - 140 version of Automatic Motor Operated & Manually Operated. The starter Electrolyte tank is made out of 3mm Thick MS sheet steel and other fabrication is of 2mm MS sheet steel. Epoxy Black Paint (for anti-Corrosion) is done inside the Electrolyte tank. Polypropylene phase barriers are provided. Movement of Moving electrodes are horizontal / vertical type as per requirement. The starter is suitable for two consecutive starts from cold & four starts per hour equally spread in hot conditions. Limit switches for interlocking purpose with spares contacts are provided in automatic version. Electrolyte filling & over flow sockets will be provided. Air break Power contactor of suitable rating is provided to suit RA of motors for final short Circuiting to the resistance.
• For Automatic Version Integral Control box (housed will main MS tank of LRS) of Suitable size will be provided. It will be having RDOL Starter of suitable rating aux. Contactor for reversing & forwarding Pilot motor & the moving electrodes, over load relay, key actuated auto/Manual Selector switch, push button, Isolating Switch, Indicating lamps and Power / Control TBs etc.
• All The motor 7 Switchgear Components used are of reputed quality. The starter is interfaced with consignee's PLC system also. The electrical interlocking circuit will be provided for consignee's PLC systems. The interlocking is such that the main motor cannot be started unless resistance is in fully "In" Position & the main motor will be tripped, if the Electrodes does not reaches to run position within Specified time. Electrolyte level indicator & temperature sensor with alarm & trip contacts can be provided on request.
