Terasaki TemBreak XS225NS 125A 3-Pole MCCB AC690V New

The Terasaki TemBreak XS225NS 125A 3-Pole Circuit Breaker protects against overcurrent in high-voltage industrial and maritime settings up to AC690V. The Terasaki Electric Co., Ltd. molded case circuit breaker (MCCB) is brand new and made in Japan. It provides better safety and performance in tough conditions.

The XS225NS model is part of the TemBreak XS standard line. It has a frame size of 225A and a rated current of 125A, making it perfect for keeping motors, transformers, and distribution systems safe from overloads and short circuits. The tiny shape makes it easy to fit into switchboards and panels, and the thermal-magnetic trip mechanism gives it accurate protection. This new unit weighs about 2.21 kg and works at 50–60Hz, thus it may be used all over the world. It meets IEC 947-2 specifications.

Key Features of Terasaki XS225NS:

1) In industrial settings, high interrupting capacity lowers the risk of arc flash and safeguards equipment that comes after it.

2) The strong molded case construction can handle tough marine and industrial situations for a long time.

3) Quick-break arc chutes and dual repulsive contacts lower let-through energy, making the system more selective.

4) The early make/late break neutral pole design keeps delicate devices safe by preventing strange voltages.

5) The toggle operation with direct opening action makes sure that the device is safely isolated and easy to reset by hand.

Applications

Ideal for ships, oil rigs, factories, and heavy machinery where AC690V systems need the best protection possible. This new XS225NS breaker makes the most of panel area while being cheaper than other options and supporting SEO-optimized installations like motor control centers. Its Japanese engineering makes sure that it has as little downtime as possible and meets all international safety standards.
