Abstract
A modular leakage current detector and machine interrupter including a sense module for detecting ground fault currents in excess of a given value, the sense module including circuitry to provide an interrupt signal, a circuit interrupter interconnected to the sense module to disconnect power to the machine upon receipt of the interrupt signal, and a test and control module electrically connected to the sense module, the test and control module providing a fault signal to periodically test the operability of and reset the modular leakage current detector and machine interrupter.
Claims7
A modular leakage current detector and interrupter comprising:
- a sense module for detecting ground fault currents in excess of a given value, the sense module including circuitry to provide an interrupt signal,
- a circuit interrupt module mounted remote from the sense module and interconnected to the sense module to disconnect power to the machine upon receipt of the interrupt signal, and
- a test and control module mounted remote from the sense module, the test and control module providing a fault signal to periodically test the operability of the modular leakage current detector and interrupter.
A modular leakage current detector and interrupter to arrest the flow of line current to an electrical load comprising:
- a sense module for detecting ground fault currents in the load in excess of a given value, the sense module including a power supply electrically connected to the line current, the power supply including a rectifier/filter and a regulator,
- interrupt circuitry responsive to the sense module to provide an interrupt signal,
- a circuit interrupter module responsive to the interrupt signal to disconnect line current to the load, and
- a test and control module electrically connected to the sense module, the test and control module adapted for mounting remote from the sense module, the test and control module triggering the sense module to test the integrity of the modular leakage current detector and interrupter and including an indicator to manifest a fault condition.
