Technical Overview and Features of the RCD Residual Current Device

The JC3LE-EV represents a specialized category of circuit protection equipment, specifically a 2-pole Residual Current Circuit Breaker with Overcurrent (RCBO). As an electromagnetic-type RCD Residual Current Device, it integrates the core functions of leakage current protection with overload and short-circuit protection into a single, compact unit. This design is engineered to enhance electrical safety in applications such as electric vehicle charging points, providing a comprehensive safeguard against various electrical faults.

A key characteristic of this RCD Residual Current Device is its robust protective performance. It boasts a high breaking capacity of 10kA, enabling it to safely interrupt severe short-circuit faults. The device offers a wide range of configurable parameters, including rated currents from 6A to 63A and trip sensitivities of 30mA, 100mA, or 300mA. It provides flexibility with a choice of type B or C tripping curves for overcurrent and A or AC types for residual current operation, allowing for precise application matching.

The design of this RCD Residual Current Device incorporates several user-oriented features that streamline installation and operation. It permits top or bottom connection, offering wiring versatility. A significant innovation is the neutral switching function, which substantially reduces the time required for on-site installation and mandatory operational testing. This feature enhances efficiency for electricians during commissioning and maintenance procedures.

A distinct dual-handle mechanism is a notable aspect of this device’s design. One handle controls the miniature circuit breaker (MCB) function for overcurrent protection, while the other independently controls the residual current protection component. This clear, separate visual indication allows for unambiguous manual control and status monitoring of both integrated protection systems, improving operational clarity.

The JC3LE-EV 2-pole RCBO is a sophisticated and versatile RCD Residual Current Device. Its combination of high breaking capacity, configurable protection settings, and user-centric design features like neutral switching and dual handles, makes it a reliable and efficient solution for modern electrical safety requirements. Its compliance with international standards IEC61009-1 and EN61009-1 confirms its adherence to established safety and performance benchmarks.
