A miniature circuit breaker is an automatically operated electrical switch designed to protect an electrical circuit from damage caused by overload or short circuit. Its basic function is to detect a fault condition and, by interrupting continuity, to immediately discontinue electrical flow. Unlike a fuse, which operates once and then has to be replaced, a miniature circuit breaker can be reset (either manually or automatically) to resume normal operation. Range : 6A to 63A      Features : 6KA short circuit breaking capacity. ISI marked. Low power consumption, thus cost effective & energy saving. Current limiting design for short circuit fault clearance up to 10000 amps. Specially designed for protection against electric shocks. Heavy contacts to bear mechanical/ electrical operations up to 50000 times. Tough fire resistant body. All moving parts are embedded in glass fiber reinforced polyester / nylon 66 material in an extra ordinary service life and a high corrosion resistance. Operates without vibration and prevents contact welding. Solid Silver contacts metal.

Mini Trip MCB's are safety devices which protect electrical installations from overloads and short circuits. Mini Trip MCB's are replacements for rewired fuses. Mini Trip MCB's are required in homes, offices and shops, these are required at every place where electricity is used.  Range : 6A to 32A      Features : 3KA short circuit breaking capacity. Compact in size. Low power consumption, thus cost effective & energy saving. Easy to mount in switchboards/ modular plates. Thermal as well as magnetic release. Finger safe terminals IP 20 degree of protection. Tough fire resistant body.

Isolators are used to make sure that an electrical circuit can be completely de-energized for service or maintenance. Such switches are often found in electrical distribution and industrial applications where machinery must have its source of driving power removed for adjustment or repair. High-voltage isolation switches are used in electrical substations to allow isolation of apparatus such as circuit breakers and transformers, and transmission lines, for maintenance.The major difference between an isolator and a circuit breaker is that an isolator is an off-load device intended to be opened only after current has been interrupted by some other control device. Features :    Conforms to IS 4064. Low watt loss. Low power consumption. Easy to mount in switchboards. Switch disconnectors for manual operation.
