ACCESSORIES LOCKS/INTERLOCKS Type Data Type Catalogue No. LOCKABLE TRIP PUSH BUTTON (LTPB) LTPB is suitable for fixed as well as draw-out manual or electrical ACBs. �or interlocking, LTPBs are offered in following combinations : • 4 different types of keys i.e. AA, BB, CC and DD suitable for 2 incomers and 1 bus coupler schemes. • Combination of L, M, N, LM and MN locks, which are suitable for three incomer and two bus coupler schemes. • Combination of K, L, M, N, KL, LM, and MN locks, which are suitable for four incomer and three bus coupler schemes. • Combination of J, K, L, M, N, JK, KL, LM and MN locks, which are suitable for five incomer and four bus coupler schemes View of the cradle Door Interlock Racking Interlock Locking in ‘Isolated’ Position * Available on request as special ACBs A) Locking in Isolated Position (LIP) The facility of locking in Isolated position is available in D/O ACBs, both Manual and Electrical Versions. This feature is useful in achieving interlocking between Mains & Standby source. (Normally 2 incomer and one bus coupler) • The key is inserted in breaker and unlocked. This ACB can then be racked in to Service position and closed. B) Door Interlock The functioning of door interlock can be explained with reference to two positions 1) Door is open and breaker in isolated Position. Door Interlock ensures that unless the door is closed, breaker cannot be racked into test & service position. 2) Door is closed and breaker in service/test position. When the breaker is in service or test position, it is not possible to open the door. C) Racking Interlock This ensures that breaker cannot be racked in/out unless it is in tripped/open condition. Mechanical Interlock It is possible to provide “Mechanical Interlock” between two breakers of the same or different ratings in vertical or horizontal configurations. Mechanical Interlock is available for ACBs upto 4000A. Mechanical Interlocking for ACBs in vertical configuration can be provided by links or by flexible cables. Same for horizontal configuration can be provided by flexible cables. Castell-lock Numbered Castell-lock can also be mounted on C-Power ACBs. This can be used to Inter-lock with other products such as S-D-� units, MCCBs etc. Castell-lock is available only for manual ACBs.
