We are offering mcb. nowadays we use more commonly miniature circuit breaker or mcb in low voltage electrical network instead of a fuse. the mcb has some advantages compared to fuse : It automatically switches off the electrical circuit during abnormal condition of the network means in over load condition as well as faulty condition. the fuse does not sense, but miniature circuit breaker does it in more reliable way. mcb is much more sensitive to over current than fuse. Another advantage is, as the switch operating knob comes at its off position during tripping, the faulty zone of the electrical circuit can easily be identified. but in case of a fuse, fuse wire should be checked by opening fuse grip or cutout from fuse base, for confirming the blow of fuse wire. Quick restoration of supply can not be possible in case of fuse as because fuses have to be rewireable or replaced for restoring the supply. but in the case of mcb, quick restoration is possible by just switching on operation. Handling mcb is more electrically safe than fuse. because of to many advantages of mcb over fuse units, in modern low voltage electrical network, miniature circuit breaker is mostly used instead of backdated fuse unit.

Two way Shunt Limit Switch is also to prevent over travel or over traverse. The Limit Switch is fitted with 2 numbers of silver cadmium bimetal (cladcon) tipped contacts which remain normally closed and supply power to the contractor coil in control panel. When the lever is moved over a projecting member fixed at a predetermined position on either side of the gantry, the power supply to the contractor coil is cut off. The contacts are rated for 10 amps at 440 Volts A. C. 50 cycles supply system.   Geared Limit Switch For Hoist Drive Heavy Duty type Limit Switches have a gear ratio of 48:1,60:1 or any desired ratio and contact rating 600 Watts 'inductive at 600 Volts A. C. 50 cycles with key way shaft extension suitable for flexible coupling. The Limited Switch will be dust proof and weather proof. Our limit switches are in the range up to 6 contacts.   Two Way Series Switch Type The Limit Switch is of series type fitted with two sets of contacts which cut off two phases. of the motor in either direction and are suitable for 440 Volts A. C. 50 cycles supply. Limit Switch Contacts are automatically reset when the lever returns to 'Zero' position due to spring action. Contacts are rated upto 60 Amps. The side covers are of cast Iron. The top and bottom covers are Sheet Steel. The Lever is of steel fitted with roller.   Hoist Limit Switch Limit Switch to prevent over hoisting will remain normally 'ON' due to the weight connected to the lever. When the Snatch block reaches the highest position the weight pulling the lever down is moved up on the snatch block. The Limit Switch is suitable for 440 volt A. C. 50 cycles supply system. This Limit Switch is of series type and the contacts are rated up to 60 amps
