CYCLIC TIMERS AC     TE 140

STAR DELTA TIMER    TE160

Cylic Timer

On Time      0.2 - 2 Hrs     Off Time 0.2 - 2 Hrs

Time can be provided as per requirement.

Star Delta

Star Time    6 - 60 Sec

Cyclic timers are used in cyclic operation of two motors where alternate pumping is required. Time can be ordered as per requirement. Standard times are 0.2 - 2 hrs seperate changeover contacts for ON and OFF times. Star delta timers are used for starting star delta motors. At power on star connection is made for selectable time after which delta connection is made.

PUMP CONTROLLER

Single Tank        TE  1010             Double Tank           TE   1020

Single tank pump controller is used to monitor the overflow and / or prevent overflow as well as switch on pump when tank empty. Useful for single tank operation of underground or overhead tank. Double tank pump controller is used to switch on pump when overhead tank is full. Dry rum protection against underground tank is also provided.

Size     :     70 x 60 x 110 mm

PHASE SEQUENCE CORRECTOR RELAY         TE1100

Used for protection of motors, pumps, transformers etc. from damage due to missing phases or negative phase sequences. A wrong sequence is corrected and two output contacts are provided which can be used to switch on the power contractors. Only the correct sequence contactor signal will be on at a time. However contactors must be interlocked during power wiring. The relay resets automatically and remains off when voltage is low, zero, unbalanced or negative phase sequence. Manual reset can be provided.

Size     :     70 x 60 x 110 mm

SINGLE PHASE PREVENTOR                 TE 400

Single phase preventor is used for protection and burnouts of pumps and motors against phase unbalance, missing and negative phase sequence. All the phases are continuously checked. A fault trip condition trips the relay - changeover contacts are enrgized. The relay resets automatically and remains off when voltage is low, zero, unbalanced or negative phase sequence. Manual reset can be provided.
