Terasaki TemBreak XE100NS 3 Pole 100A MCCB

Terasaki TemBreak XE100NS | 3-Pole 100A Molded Case Circuit Breaker (MCCB)

The Terasaki TemBreak XE100NS epitomises Japanese circuit protection engineering. This high performance 100 Amp, 3-pole Molded Case Circuit Breaker (MCCB) of the XE series is designed for the tough conditions of marine and heavier industrial applications. It is the best solution for high density electrical panels, when safety is not optional but space is a premium. Its compact frame does not compromise on breaking capability.

Guidance and Tips from Our Engineer:

In my experience on VLCCs and bulk carriers, the XE100NS is the ‘workhorse’ of the sub-panel. While many engineers focus only on the Amp rating, always pay attention to the $I_{cu}$ (Ultimate Breaking Capacity). At 25kA (415V), this unit is exceptionally robust for its size.

Tips:

1. Connection Torque. Always use a calibrated torque wrench for the terminal bolts. Loose connections on a 100A breaker lead to localized heating, which is the #1 cause of nuisance tripping and eventual fire hazards in engine room panels.
2. Environment. If installing in a high-salt environment, ensure the enclosure has adequate ventilation but use a thin coat of dielectric contact grease on the busbar connections to prevent galvanic corrosion.
