Description
The TERASAKI ELECTRIC XS1600NE is a high-current molded-case circuit breaker from the Terasaki TemBreak family. It is designed for high-capacity electrical distribution and protection applications. The XS1600NE is rated up to 1600 A, with a 3-pole configuration and 50/60 Hz operating frequency. Terasaki documentation identifies the XS1600NE as a 1600 A breaker, while the available product listing specifies AC 690 V insulation voltage.
The breaker is suitable for industrial power distribution, marine electrical systems, switchboards, machinery power circuits, and other high-current applications where reliable circuit isolation and overcurrent protection are required.

⚙️ Technical Overview
The XS1600NE belongs to Terasaki’s high-current TemBreak breaker family. Terasaki’s documentation lists the S1600-NE at 1600 A with a high fault-level performance of 85/65 kA under the specified test conditions.
The XS1600NE is also identified in Terasaki documentation as a 1600 A molded-case circuit breaker. The manufacturer’s discontinued-products information confirms that XS1600NE is an older/discontinued model, making correct identification important when sourcing replacement equipment.
🔌 Electrical Application
This breaker can be used in high-current distribution systems where circuit protection and isolation are required. Depending on the exact configuration, accessories may include auxiliary contacts, shunt-trip equipment, undervoltage releases, or motor-operated mechanisms.
For replacement applications, verify the complete nameplate information, pole configuration, rated current, voltage rating, trip-unit configuration, accessory modules, terminal arrangement, and mounting dimensions before commissioning.
🛠️ Installation & Inspection
Before installation, inspect the breaker housing, terminals, operating mechanism, trip mechanism, and accessory wiring. Confirm that the system voltage and available fault current are compatible with the breaker rating.
For an existing installation, compare the complete XS1600NE identification with the original breaker rather than relying only on the model number. This is particularly important because accessory and operating-mechanism configurations can differ between individual units.
