Power Relays, Over 2 Amps

The G7L-2A-P-CB AC12 power relay is an electrical switch device in the electrical circuitry of installations that accomplish a wide range of application assignments. Power relays can control a large circuit with a small current, and their applications are vast. The G7L-2A-P-CB AC12 surpasses other relays in terms of its load capacity and height, which make it suitable for a variety of tasks.

Applications

The G7L-2A-P-CB AC12 power relay can be used to switch devices on and off, to establish and break circuits, and to make switching operations, including the startup, operation, and cut-off of circuits. It can also be employed in the start-up and shut-down of transformers, and it can, if the situation requires it, be connected in series with other relays to hold or release a larger number of circuits. Moreover, it can even be used as a controller for electromechanical operations or actuators.

Typical applications for this power relay include home and office automation, motor and electric drive control, medical equipment, and industrial building control.

Working Principle

The G7L-2A-P-CB AC12 power relay works on the principle known as "contact separation." Put simply, contact separation is the act of keeping two pieces of metal that are in close contact physically and electrically separated. The action of contact separation is achieved through the mechanical actuation of electromagnetic coils.

When the power relay is energized (power is applied), the electromagnetic coils are energized and create a magnetic field that attracts the armature and causes it to move axially away from the contacts. This action separates the two contacts in the relay and disconnects the circuit. When the power is removed from the relay, the magnetic field collapses and the armature is pushed back by a spring, closing the relay into the on position once again.

Specifications

The G7L-2A-P-CB AC12 power relay features a dielectric strength of 4,000VAC, a surge voltage of 6,000V, a switching capacity of 1,000VAC, and a contact rating of 2 amps (AC) or 1 amp (DC) with a maximum switching voltage of 48V (AC/DC). It has a body size of 11.50mm x 10mm, a height of 11.75mm, and an AMP rating of 5A @ 28V, 5A @ 240V, and 7.5A @ 125V. It also features terminals with a Positive-opening design, a self-reset function, and an operating temperature range of -30°C to 70°C.

Conclusion

The G7L-2A-P-CB AC12 power relay is widely used in a variety of applications due to its range of features and specifications. Its most commonly used applications are in home and office automation, motor and electric drive control, medical equipment, and industrial building control. Thanks to its impressive load rating and striking design, the G7L-2A-P-CB AC12 is a top choice for many industrial and commercial needs.
