ABB E204/100G Modular Disconnector, 100A, 4-Pole

The ABB E204/100G is a high-performance modular disconnector engineered for the secure isolation of electrical circuits. Designed to handle a rated current of 100A, this 4-pole device provides a robust solution for switching and disconnecting power in both industrial and commercial electrical distribution systems. Its compact modular design allows for seamless integration into standard distribution boards, ensuring that maintenance and emergency shutdowns can be performed with maximum safety and efficiency.

Advantages

This modular disconnector stands out due to its reliable construction and adherence to high safety standards. By providing a clear physical break in the circuit, it ensures that downstream equipment is safely de-energized during maintenance operations. The device is built for durability and consistent performance under load, making it an essential component for modern electrical infrastructure. Its compatibility with DIN-rail mounting systems simplifies the installation process, allowing for quick and organized assembly within electrical panels.

Suitable for

• Industrial electrical distribution boards
• Commercial building power management
• Safe isolation of electrical circuits during maintenance
• Main power switching in modular installations

This device may not be suitable for applications requiring high-speed automatic circuit breaking or protection against short-circuit faults, as it functions primarily as a manual isolation switch rather than a circuit breaker. It is also not intended for use in environments exceeding its specified voltage or current ratings, nor is it designed for outdoor installation without an appropriate protective enclosure.

Key specifications

• Rated current: 100A
• Number of poles: 4
• Mounting type: DIN-rail
• Device type: Modular disconnector

To use the ABB E204/100G, mount the unit onto a standard DIN-rail within your distribution board. Ensure that all electrical connections are tightened to the manufacturer's specified torque settings to prevent overheating or poor contact. The toggle switch on the front of the unit allows for manual operation to connect or disconnect the power supply to the downstream circuit.

What to consider before purchase

• Verify that the 100A rating matches your circuit requirements
• Ensure there is sufficient space on the DIN-rail for a 4-pole module
• Confirm that the application requires a manual isolation switch

Always ensure that the power supply is verified as disconnected using appropriate testing equipment before performing any maintenance on the downstream circuit. Regularly inspect the terminals for signs of wear or loose connections to maintain optimal performance.
