MADE IN JAPAN
The Terasaki Tembreak XS1600NE is a heavy-duty 3-pole air circuit breaker rated at 1600A and up to AC 690V, 50–60Hz, designed for high-current protection and switching duties within marine main and distribution switchboards. Equipped with a Type XMC 9 motor operator, shunt trip unit, and auxiliary switches, this breaker is built for automated and remotely controlled power distribution systems aboard commercial and naval vessels. As a core component in the Air Circuit Breaker category, it plays a critical role in protecting ship electrical systems from overload and fault conditions while enabling safe, controlled isolation of power circuits.
Key Features
✓ Rated at 1600A with a maximum insulation voltage of AC 690V at 50–60Hz, making it suitable for high-load marine power distribution circuits.
✓ Fitted with the XMC 9 motor operator (AC 100–115V, 1.0A) enabling remote electrical closing and opening, reducing the need for manual intervention in switchboard operations.
✓ Shunt trip unit rated 200–480V allows for remote tripping of the breaker upon receipt of an external signal, supporting emergency shutdown and protection schemes.
✓ Auxiliary switch contacts rated AC 480V/3A, DC 250V/0.3A and AC 250V/5A, DC 125V/0.6A provide status feedback for integration with control and monitoring systems.
✓ Manufactured in Japan by Terasaki Electric Co., Ltd., a recognised supplier of marine-grade switchgear; suitable for installation within main switchboards, emergency switchboards, and section distribution panels.
Marine Applications
✓ Main switchboard and bus-tie breaker applications aboard cargo vessels, tankers, and bulk carriers requiring reliable high-current circuit protection.
✓ Emergency switchboard configurations on passenger ferries and ro-ro vessels where automated tripping and remote operation are operationally essential.
✓ Power management system integration on offshore support vessels and platform supply vessels, where motor-operated breakers support load-shedding and fault isolation.
✓ Propulsion-related distribution panels on container ships and cruise vessels where high-integrity switching of large electrical loads is required.
✓ Replacement and refit projects on vessels originally equipped with Terasaki Tembreak switchgear, ensuring OEM-compatible performance and system continuity.
