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 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.

RCBO (Residual Current Breaker with Over-Current) is an important electrical protection device that combines the functions of a miniature circuit breaker (MCB) and a residual current device (RCD). This integration enables the RCBO to provide comprehensive protection against two types of electrical faults: residual current (leakage) and overcurrent.

Residual current, or leakage, occurs when a circuit is accidentally interrupted due to factors such as poor electrical wiring or a DIY accident. For example, drilling through a cable when installing a picture hook or accidentally cutting it with a lawnmower can cause leakage. In this case, the electrical current will seek the path of least resistance, possibly through a lawn mower or drill, and reach the body, creating a risk of electrocution.

On the other hand, overcurrent comes in two forms: overload and short circuit. Overloading occurs when a circuit is burdened with too many power-hungry devices that exceeds the capacity of the cable. A short circuit, on the other hand, is caused by a direct connection between a live conductor and a neutral conductor, causing a rapid surge of current that can be very dangerous.

While conventional RCDs only protect against leakage, MCBs protect against overcurrent, and RCBOs provide complete protection against both types of faults. By detecting and responding to residual current and overcurrent conditions, RCBOs play a key role in ensuring electrical safety in a variety of applications, including residential, commercial and industrial environments.
