ABB E2N2000 is a low voltage air circuit breaker belonging to the SACE Emax E2 series. It is designed for main power distribution in industrial and commercial facilities. This device offers reliable protection against overload, short circuit and earth fault for AC power systems. It features high breaking capacity and stable performance to ensure safe and continuous power supply.

E2 represents the frame size of the circuit breaker. N stands for the breaking capacity level. 2000 means the rated working current of this model is 2000 A. It can be equipped with different types of trip units to meet various protection demands.

The rated current is 2000 A. It is available in 3 pole and 4 pole versions. The rated operational voltage reaches 690 V AC, and the rated insulation voltage is 1000 V AC. The ultimate short circuit breaking capacity is 55 kA. Optional trip units include PR121/P, PR122/P and PR123/P. The working temperature ranges from minus 5 degrees Celsius to 40 degrees Celsius. It supports fixed and withdrawable installation modes. The product complies with IEC 60947-2 standard, and has passed CE and RoHS certifications.

This circuit breaker is equipped with standard power wiring terminals for circuit connection. Optional communication modules can be installed to support Modbus and Profibus protocols. It realizes remote data collection, status monitoring and parameter control through communication interfaces. Auxiliary contacts are reserved for signal output and interlock control.

It provides adjustable long time overload protection, short time and instantaneous short circuit protection. The matched trip unit can also realize sensitive earth fault protection. It can serve as an isolation device to cut off the circuit safely during maintenance. It has excellent mechanical endurance to adapt to frequent switching operations. The communication function supports remote monitoring and system linkage.

It is widely used for incoming power feeders of industrial workshops and factories. It applies to power distribution cabinets in commercial buildings and large public facilities. It is suitable for protection and control of transformers and generators. It can also be deployed in data centers and other critical low voltage power distribution systems.

Install the device inside standard power distribution panels and complete reliable grounding. Check all electrical connections and mechanical parts regularly to prevent loose contacts. Confirm the protection parameter settings match the on-site operating requirements. Keep the internal contacts and cabinet interior clean and dry. Follow official maintenance cycles for regular inspection and lubrication. Take anti-static measures when replacing or debugging trip units and communication modules. Avoid operation beyond the specified temperature range.
