Adjustable TGM2E2-Y 400v LCD Screen Molded Case Circuit Breaker
TGM2E2Y series residual current circuit breaker is suitable for ac
50 hz, rated voltage 400 v, rated insulation voltage 1000 v, rated
current 630 a three-phase four-wire neutral point grounding of low
voltage power grid directly, in addition to the residual current,
overload and short circuit protection, also can to zero, under
voltage, over voltage, phase and phase sequence errors, also can
prevent the damage of equipment insulation due ground fault caused
by the fire danger.
The series circuit breaker for the liquid crystal display (LCD),
the current way is electronic type, can be adjusted according to
the capacity of transformer or loads. Three protection value is
adjustable, and can implement graded protection and circuit breaker
with higher and lower. Overcurrent protection of high precision,
small environmental impact, is the ideal choice for customers.
