Introduction:
JCB2LE-80M RCBO (residual current circuit breaker with overload protection) provides protection against earth faults, overloads, short circuits. They are suitable for consumer units or distribution boards, applied under occasions such as industrial, and commercial, high-rise buildings and residential houses.
JCB2LE-80M RCBO is more safe with both disconnected neutral and phase guarantees its proper actuation against earth leakage faults even when the neutral and phase are wrongly connected.
JCB2LE-80M is a electronic type RCBO, which incorporates a filtering device preventing the risks of unwanted due to transient voltages and Transient currents.
JCB2LE-80M RCBOs feature dual pole switching with live and neutral disconnection. Available as Type AC (for alternating current only) or Type A (for alternating and pulsating DC currents)
JCB2LE-80M RCBO in 2 pole and 1P+N is a high-quality residual current circuit breaker and miniature circuit breaker combination with line voltage-dependent tripping and a wide variety of rated tripping currents. The built-in electronics precisely monitors where the currents flow. The difference between harmless and critical residual currents will be detected.
JCB2LE-80M ROBO is available in 6A, 10A, 16A, 20A, 32A, 40A, 50A, 63A, 80A. Large selection of current ratings for all commercial and industrial applications. Tripping sensitivity is available in 30mA, 100mA, 300mA. It is available in B Type or C type tripping curves. It is also available in a low voltage version designed to be used on 110V systems. Inbuilt test button operates at rated voltage
JCB2LE-80M RCBO provides indirect protection to the operator’s body under such a situation that the exposed live parts should be connected to a proper earth pole. It also provides overcurrent protection to circuits in the household, commercial, and other similar installations. Moreover, it prevents potential fire danger caused by earth fault current in case the overcurrent protection device fails.
JCB2LE-80M RCBO has a 6kA rating ideal for commercial and residential applications. The RCD/MCB combo will protect property and life should current be detected leaking to earth within 30mA. The switch has an inbuilt test switch and is easily reset after the fault is rectified.

What is an RCBO and How Does it Work?
RCBO stands for 'Residual Current Breaker with Over-Current'. As the name suggests it protects against two types of fault and in essence combines the functionality of an MCB and RCD.
Let us first remind ourselves of those two faults:
1.Residual Current, or Earth Leakage - Occurs when there is an accidental break in a circuit through poor electrical wiring or DIY accidents such as drilling through a cable when mounting a picture hook or cutting through a cable with the lawn mower. In this instance the electricity must go somewhere and choosing the easiest route travels through the lawnmower or drill to the human causing electric shock.
2.Over-Current takes two forms:
2.1 Overload - Occurs when too many devices are in use on the circuit, drawing an amount of power which exceeds the capacity of the cable.
2.2 Short Circuit - Occurs when there is a direct connection between the live and neutral conductors. Without the resistance provided by the normal circuit integrity, electrical current rushes around the circuit in a loop and multiplies the amperage by many thousand times in just milliseconds and is considerably more dangerous than Overload.
Whereas an RCD is designed solely to protect against earth leakage and an MCB protects only against over-current, an RCBO protects against both types of fault.
