BCH Electric Limited is the manufacturer of Motor Protection Circuit Breaker (MPCB) in India. Our motor protection circuits are suitable for motor protection.
Overview The term MPCB refers to Motor Protection Circuit Breaker. An MPCB is a circuit breaker designed specifically for protecting electric motors against overloads, short circuits, under voltage, and phase losses. The motor protection circuit breaker (MPCB) protects the motor from faults using a thermal-magnetic circuit breaker. For electric motors, the selection of the MPCB depends upon the motor’s full load current and the maximum short circuit current possible. MPCBs are available for different voltage levels, generally around 230 V to 660 V. They are unique in that they can withstand starting currents without interrupting the circuit. Functions of MPCB:- Motor protection circuit breakers, or MPCBs, are specialized electromechanical devices that can be used with motor circuits at both 60Hz and 50Hz. Several functions allow it to provide a safe electrical supply for motors: A protection system against electrical faults, such as short circuits, line-to-ground faul...
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 switches and their working principle: The limit switch is 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...
