Mitsubishi AE1600 SW 1600A 3P Low Voltage Air Circuit Breaker

Mitsubishi AE1600 SW Air Circuit Breaker Details:

The MITSUBISHI AE1600 SW 1600A 3-pole low-voltage air circuit breaker provides heavy-duty protection for incoming or feeder circuits in low-voltage power distribution boards up to 690 V AC. The electronic trip relay and high breaking capacity design (Icu = Ics = 65 kA at 500 V AC) ensure exact overload, short-circuit, and ground fault protection for sensitive loads.

The AE-SW series features arc-extinguishing chambers, strong mechanical interlocks, and a high surge resist capability, ensuring safe interruption and reliability in challenging working situations. This main breaker is ideal for use in MCCs, switchboards, and maritime panels due to its fixed 3-pole structure, 1600 A frame, and large adjustable current range.

Optional attachments, such as shunt trip, undervoltage trip, auxiliary contacts, and front/vertical terminal adapters, enable versatile configuration for remote control, monitoring, and integration with modern protection and automation systems.

What are the benefits?

1) Strong breaking capacity: Icu = Ics = 65 kA at AC 500 V, which means that strong fault currents can be safely stopped in low-voltage distribution systems.

2) Wide range of rated voltage and current: up to 690 V AC and 1600 A, with Ir adjustable from 800 to 1600 A, making it suitable for a wide range of feeder and main incomer applications.

3) Electronic trip relay: precise settings for overload, short circuit, and ground fault protection that improve coordination and cut down on false trips.

4) High dependability and long life: it can handle thousands of mechanical and electrical operation cycles, making it good for frequent switching and long service life.

5) Complies with IEC 60947-2, EN 60947-2, and JIS C 8201-2-1, which are worldwide specifications for use in OEM panels and projects.

Applications:

• Industrial plants (steel, cement, chemical, and manufacturing) for motor control, process distribution, and heavy loads.
• Switchboards for marine and offshore applications, including engine room distribution and auxiliary power systems.
• Data centers and IT facilities that handle main LV distribution, UPS input/output, and generator tie breakers.
• Power generating and low-voltage substations for transformers and generators.
• LV protection is crucial for renewable energy facilities and large HVAC systems that demand great capacity and dependability.
