EARTH LEAKAGE CURRENT

DETECTOR

DESCRIPTION

The UTC M54133 is a semiconductor integrated circuit

developed for use in high-speed earth leakage breakers

incorporating functions to protect against voltage surges and

inverter noise.

FEATURES

* Improvement of ability against unwanted tripping by

lightning-surge and lightning impulse.

Two times counting system adopted.

* Improvement of ability against unwanted tripping by

inverter-noise.

Built-in operational amplifier (of low current dissipation) for active

low-pass filter.

Improved high-frequency, high harmonic superposition

performance

* Internal time delay function

* An external capacitor is used to set the delay time.

* High stabilities design

Adopt the circuits that is not affected by fluctuations of supply

voltage/ambient temperature.
