🔌 Protection & Electrical Configuration

The XS1600NE belongs to Terasaki’s electronic OCR-type XS series. For the 1600A frame, the documented adjustable current range includes configurations from 600A through 1600A. The exact protection settings depend on the trip-unit configuration installed on the individual breaker.

Some versions may include:

Overcurrent protection
Electronic trip unit
Auxiliary contacts
Shunt trip
Motor operator
Emergency switchboard accessories
Front or rear connection arrangements

The accessories are configuration-dependent, so the actual breaker should be checked before ordering replacement parts or accessories.

🏭 Typical Applications

The XS1600NE is suited to high-current distribution and protection duties such as:

Main distribution switchboards
Industrial electrical panels
Generator switchboards
Marine switchboards
Large motor distribution systems
Factory power distribution
Shipboard electrical systems
Emergency power distribution
High-current feeder protection

Terasaki’s selection documentation specifically notes the XS series for applications rated at 40°C, with a 45°C rating referenced for marine applications.

🔧 Installation & Maintenance Notes

Before replacing an existing breaker, confirm the complete model number and configuration. In particular, check:

XS1600NE model marking
Number of poles
Rated current setting
Trip-unit configuration
Rated voltage
Auxiliary switch arrangement
Shunt-trip voltage
Motor operator voltage
Connection type
Mounting arrangement

For a 1600A breaker, terminal and connection hardware should be checked carefully. Terasaki documentation specifies M12 terminal hardware and a tightening-torque range of approximately 40.2–65.7 N·m for the relevant XS1600NE connection arrangement. Always follow the applicable Terasaki manual for the exact configuration being installed.

Before energizing the circuit, inspect the breaker body, terminals, insulation surfaces and operating mechanism. Verify that the breaker opens, closes and trips correctly according to the maintenance procedure for the installation.
