LV Switchgear Components
We have wide of LV Switchgear Components in our product range.
A Miniature Circuit Breaker (MCB) is an automatically operated electrical switch used to protect low voltage electrical circuits from damage caused by excess current from an overload or short circuit. MCBs are typically rated up to a current up to 125 A, do not have adjustable trip characteristics, and can be thermal or thermal-magnetic in operation.
The miniature circuit breaker is a protective device equipped with both a thermal and an electromagnetic release that is available in 1-, 2-, 3-, 4-, 1+N and 3+N pole versions. It is available with rated currents of 0.16 A to 125 A. Depending on the device type, the switching capacity is 20kA or 15 kA or 10 kA according to IEC/EN Standards.
An ECLB is one kind of safety device used for installing an electrical device with high earth impedance to avoid shock. These devices identify small stray voltages of the electrical device on the metal enclosures and intrude the circuit if a dangerous voltage is identified. The main purpose of the Earth leakage circuit breaker (ECLB) is to stop damage to humans & animals due to electric shock.
The main function of an Earth-leakage circuit breaker or ELCB is to prevent shock while electrical installations through high Earth impedance because it is a safety device. This circuit breaker identifies tiny stray voltages on top of the electrical equipment with a metal enclosure & disrupts the circuit if a hazardous voltage is identified. The main purpose of ELCBs is to avoid harm to human beings as well as animals because of electric shock.
The residual current device (RCD) or residual current circuit breaker (RCCB) enables the fast disconnection of electricity, thereby avoiding prolonged and potentially serious shocks to human beings. An RCD device complete with overcurrent protection is called an RCBO, or residual current circuit breaker with overcurrent protection.
The primary functions of RCBOs are to ensure protection against earth fault currents, overload, and short circuit currents in an electrical circuits. It is recommended that an RCBO be attached to each separate circuit, meaning that a fault in one circuit will not affect the functioning of the others. Such devices allow for disconnection of the circuit for the protection of people and equipment in the event that the current becomes unbalanced. They can be operated exclusively of other overcurrent protective devices within the rated short-circuit capacity.
The Molded Case Circuit Breakers are used for higher current applications where MCBs are unable to use. The MCCB system uses a temperature-sensitive device also known as the thermal element along with a current sensitive electromagnetic device which is also known as the magnetic element in order to provide the overall trip mechanism which is relied for protection and isolation purposes. The MCCB basically utilizes a temperature-sensitive device which is also known as the thermal element with a current sensitive device are the magnetic elements to provide the protection and isolation which enables the MCCB device to provide overload protection along with electrical fault protection from any type of short circuit situations and also electrical switch for immediate disconnection.
An Air Circuit Breaker (ACB) is an electrical device used to provide Overcurrent and short-circuit protection for electric circuits over 630 Amps to 10K Amps. Air circuit breaker is circuit operation breaker that operates in the air as an arc extinguishing medium, at a given atmospheric pressure. There are several mode of operation for tripping device is used in an ACB. The Electronic protective device used in an ACB is with LSIG protection.
