JCB2LE-40M: Compact Electronic RCBO Series

The W9 Group JCB2LE-40M is a state-of-the-art Electronic Residual Current Circuit Breaker with Overcurrent Protection (RCBO). Engineered for modern electrical distribution, this device combines compact design with robust safety features, ensuring comprehensive protection against earth leakage, overload, and short circuits.

Designed to meet the rigorous IEC 61009-1 and EN 61009-1 standards, the JCB2LE-40M is the ideal solution for installers seeking efficiency, flexibility, and compliance with ESV verification requirements.

Key Features & Benefits

Superior Protection
Comprehensive Safety: Provides integrated protection against earth leakage, overload, and short circuits in a single unit.
High Breaking Capacity: Rated up to 6kA, ensuring the device can safely interrupt high fault currents.
True Double Pole Disconnection: Guarantees complete isolation of faulty circuits by switching both Line and Neutral poles, significantly enhancing safety during maintenance.

Space-Saving “SLIM” Design
Compact Module: The innovative slim design allows for a higher density of RCDs/MCBs to be installed within a single enclosure, saving valuable panel space.
Single Module RCBO: Delivers full double-pole protection within a footprint that maximizes installation flexibility.

Installation & Commissioning Efficiency
Top or Bottom Entry: Offers flexible installation with the choice of line connection from either the top or bottom.
Insulated Busbar Openings: Designed for easy and safe busbar installations.
Universal Screw Compatibility: The combination head screws are compatible with multiple types of screwdrivers, streamlining the installation process.
Reduced Testing Time: The neutral pole switching capability significantly reduces the time required for installation and commissioning tests.

Versatile Specifications
Wide Current Range: Available in ratings from 2A to 40A (2A, 6A, 10A, 20A, 25A, 32A, 40A).
Tripping Curves: Available in Type B or Type C curves to suit different load characteristics.
Sensitivity Options: Available in 30mA (personal protection) and 100mA (fire protection).
Leakage Types: Choose between Type A (pulsating DC and AC) or Type AC (AC only) to match specific application needs.

The JCB2LE-40M is designed for versatility across residential, commercial, and light industrial environments.

Residential & Apartment Complexes
Scenario: Protecting individual circuits in modern apartments where space in the distribution board is limited.
Benefit: The SLIM module design allows electricians to fit more circuits into standard consumer units. The 30mA Type A variant is perfect for protecting sockets and lighting where modern electronics (like dimmers or inverters) might generate pulsating DC leakage.

Commercial Office Buildings
Scenario: Distribution boards feeding office outlets, HVAC systems, and lighting.
Benefit: The True Double Pole Disconnection ensures safe isolation for maintenance teams working on office power grids. The C-Curve options are ideal for circuits with small motors or fluorescent lighting banks that have moderate inrush currents.

Light Industrial & Workshops
Protection of machinery and power tools.
Benefit: With a 6kA breaking capacity, the JCB2LE-40M can handle the higher fault currents often found in industrial settings. The 100mA sensitivity option can be used for fire protection on feeder circuits, while 30mA protects specific operator workstations.

Retrofit & Renovation Projects
Upgrading old fuse boxes or distribution panels where space is constrained.
Benefit: The top/bottom entry flexibility and compatibility with standard busbars make it easy to integrate into existing infrastructure without extensive rewiring.
