These types of relays consist of bimetallic elements, which are individually calibrated and tested for optimum protection of motors against overloads. The tripping curve shows the inverse time characteristic of all bimetallic relays starting from cold condition. Once the realy is tripped due to overload it cannot be reset immediately as the relay has a specific reset time. Resetting is done maually. Wide range of relays are available depending on various ac loads.

Offers manually operated mini motor starter. Type: gf-1 range: 0.5 to 7.5 hp ght's gf-1 manually operated motor starter is suitable for single-phase motors upto 2hp and three phase motors upto 7.5hp. The starter operates on quick break & trip free mechanism & is designed for smooth & reliable performance. Range wide range of relays is available depending on various ac loads. For actual range see relay section table. Overload trip reset once the relay has tripped due to overload the starter cannot be reset until the bimetal elements have cooled down sufficiently. Contact system the silver alloy tipped contacts ensure long electrical life & can be easily accessed for inspection or replacement. Applications gf-1 starters are most economical & have wide applications. They are perfectly suited for motor installations where no-volt coil or remote onoff is unnecessary or undesirable. Some applications include switching & overload protection of air compressors, exhaust fans, unattended pumps, etc.

Offers gk- I type control panels. Protection of valuable motors cannot be achieved by mere switching 'on' & 'off' devices. Where as gk-1 type control panels are designed for absolute protection of motors against single phasing, under voltage, overload & dry running. 1ph control panel : range 11.52 hp d.o.l control panel : range 3-8 hp star-delta control panel : range 7.5-15 hp construction control panels mainly consists of gk-1 range of overload relays, contactors along with single phase preventers; back up fuses, ammeter, voltmeter, pilot lamps & other panel accessories.

Offers ghd overload relays. Ghd type overload relays are compact in design. They also have bimetallic elements, which are calibrated and tested for precise operation. Their tripping curve is similar to gk-1 type of relays except that they operate on differential mechanism technique. Resetting of ghd relay can be done both manually or automatically. Range (0.3 - 0.48a) to (22 - 30a) ghd contactors these heavy-duty contactors have a robust construction and are designed for trouble free and long operation life. They can withstand high ambient, humidity, under voltage conditions and frequent starts.

Offers gdh type control panels. Protection of valuable motors cannot be achieved by mere switching on and off devices. Where as ghd type control panels are designed for absolute protection of motors against single phasing, under voltage, overload & dry running. 1ph control panel : range 11.52 hp d.o.l control panel : range 3-8hp star-delta control panel : range 7.5-15hp.

Offers direct on line motor starter. Type: gl - 2 gl - 3 range: 10 to 30 hp gl - 2 type " ganga" d.o.l motor starters have robust construction and offers smooth and reliable performance. They are designed to meet the most stringent requirements of both industrial and agricultural fields. These motor starters comply with requirements of is standards. Thermal overload relay the gl - 2 relay consists of bimetallic elements, which are individually calibrated & tested for precise operation. An extra 'no' contact is provided to give clear warning when overloading of motor occurs. Once they relay has tripped due to overload the starter cannot be reset until the bimetal elements have cooled down sufficiently. Contact system the silver alloy tipped contacts ensure long electrical life & are bounce free when closed. They can be easily accessed for inspection or replacement. Magnet system & coil laminated 'e' stampings are used for construction and are designed for low loss. Shading rings are provided to reduce hum & chatter. Coils are layer wound and are designed for long life. They consume less power & can withstand wide voltage fluctuations particularly in rural areas.

Offers thermal overload relays. Gl0, gl1, gl5, gl2, gl3 contactors are rugged & designed for trouble free switching of ac motors and other ac loads. They can withstand high ambient, humidity, under voltage conditions and frequent starts. Depending on their current ratings & specifications they are classified as fallows, type : gl0gl1gl1.5 range : 12a16a25a. type : gl2gl3 range: 32a40a construction the bakelite housing of the contactor has a very high degree of insulation. Current carrying contacts are of silver alloy and hence have a long electrical life. Auxiliary contacts are provided for control and interlocking purposes. Laminated 'e' stampings are used for the magnet construction and the coils are designed for long life and can withstand wide voltage variations.
