BSB PREVENTOR

SINGLE PHASING PREVENTOR

TYPE : BSP/BAP/BAP/ (SD)

BSP         -Single Phasing Preventor

BAP        -Single Phasing Preventor with auto operation

BAP (SD) – Single Phasing Preventor with auto operation Star Delta

 

BENTEX-SKN Single Phasing Preventor is negative sequence voltage operated single phasing preventor and can be used for all types of 3-phase motors. This preventor is an Auxiliary relay and hence should be used alongwith motor starter. Effective working of motor starter with which it is to be coupled.

 

AUTO-SWITCH OPERATION :

BENTEX-SKN  Single Phasing Preventor can be connected as ‘Auto-Switch’ for automatic operation (ON /OFF) during power failure. As mentioned below in No. 5 give sensing to 7, 8 & 9 before the starter (At incoming). Connect a short-link or Toggle Switch across on-push will enable Bentex Single Phasing Preventor to Work as Auto-Switch.
