  A Solid-state relay is an electronic device that switches on or off when a small external voltage is applied across its control terminals. They are semiconductor equivalents of the electromechanical relay and can control electrical loads without moving parts. For example, it controls the AC power for ON/OFF switching, motor speed control, light dimming, or other such applications power control is needed. Using a solid-state relay, These AC loads can be easily controlled with a low current DC voltage, providing long life and high switching speeds.  The life expectancy of Solid State Relay is over 100 million operations. It is widely used in heating control, Motor control, capacitor switching and lighting control, solenoid, transformer control, and air conditioning applications. In addition, this electronic switching device is used for external voltage (AC or DC) for controlling terminals. While serving the same functions as an electromechanical relay, expect moving parts.

Overload Relay:  Overload relay is an electrical device designed as the heating prototypes of the electric motor. It breaks up the flow of current when the heat-detecting device in the relay attains a fixed temperature. An overload relay device can be prepared with a heater linked with generally closed connections that unlocks when the heater gets extremely hot. Principle Of Overload Relay Operation When excess current is drawn into the motor, it causes an overload. This causes overheating of the motor and may damage the motor. Thus, it is required to protect the engine, circuits, and branch circuit components from overload conditions. Overload relays protect the motor and branch circuit components from an overload. Overload relays monitor the flow of current in the circuit. Suppose the current rises above a specific limit over a particular time. In that case, the overload relay will trip, performing a supplemental contact that suspends the motor control circuit. This leads to th...

  Limit switch are switches operated by a machine part's motion of an object's presence. Limit switches use control machinery as a security interlock, a part of an impact system, or to count objects passing to some extent. Limit switches are electromechanical equipment containing an actuator mechanically connected to a group of contacts; when an object comes in-tuned with the actuator, the machine operates the contacts to form or cut an electrical connection. Limit switches are applied in multiple applications and environments due to their ruggedness, simple fitting, and operation reliability. Limit switches can ascertain the proximity or absence, passing, positioning, and travel of an object. Limit switches were first wont to define the limit of travel of an object, hence the name "Limit Switch." Working Principle Limit switches with a roller-lever operator; are connected to a gate on a canal lock and indicate a gate's position to an impact system. Limit switc...

  Power factor is the ratio between the KW and the KVA drawn by an electrical load. Where the KW is real power to load and KVA is the apparent load power. It is the measurement how an electrical equipment getting current in actual. Example: A load with power factor of 0.85, results much higher losses in supply system and consumer has to pay higher bill. Little improvement in power factor lead to significant reduction in losses since losses are proportional to square of the current. APFC panels  are built to correct the power factor and major components needed to build power factors are: LT Capacitors Capacitor duty Contactors or Power Contactors MCB Wires APFC Relay Enclosure Each components requires to be heavy duty and safe functioning to sustain heavy inrush currents of capacitor and timely switching of capacitor to achieve the required power factor correction BCH LT Capacitors are safe to avoid any bursting and made with thick polypropylene films. Easily available from 1KV...

Electrical appliances are an essential part of all households. Right from lights and fans to leisure appliances like microwaves and washing machines operate via electricity. An electric circuit provides required charges to the devices for their efficient functioning. But what keeps the circuit intact and unimpaired? Power always brings its own set of responsibilities, so does the electric power circuit with the responsibility of our home’s protection. The most frequent issue with the power circuits is the current overflow, and to control the disorder caused by the excess flow of current, circuit breakers are introduced. If yo u  are confused about selecting the ideal MCB, We recommend choosing BCH MCBs; these MCBs are a blend of superior grade material and manufacturing. BCH is the best growing brand for  MCB s and was the leading brand in 2020. Here is an extensive guide for understanding MCB and how to choose the best one for yourself. What is MCB? The complete form of MCB i...
