1.Application
GSB2L-63 range leakage circuit breakers by GSB2 range of miniature circuit-breaker modules to install residual current operated circuit breakers, which applies to the AC 50Hz or 60Hz, rated voltage to 415V, rated current between 63 and the following circuit , As an addition to the personal indirect electric and shock equipment failure caused by insulation protection leakage purposes, but also on the line overload and short circuit protection . Under normal circumstances, also as a line of non-frequent switching and motor does not start frequently used.
2.Working condition and installation condition
Environment temperature : -5℃～+40℃, the average hours of temperature exceeding +35℃ during 24 hours.
3.Structure and working principle
Leakage module by the zero sequence current transformers, electronic power amplifier module and electromagnetic release component, and its linkage rod through the small circuit breakers with GSB2 institutions linked trip. When the circuit appears to be the protection of insulation failure of electric shock or personal accident, zero sequence current transformer in one side of the instantaneous current vector and non-zero (IA + IB + IC + IN ≠0 transformer secondary windings will produce induced voltage, the voltage by the electronic power amplifier module to enlarge after the release of the release of electromagnetic coils, when the leakage current setting to achieve the value of the action, the release of electromagnetic pull-in, so that the pull-bar linkage circuit Sub-gate, the main circuit breaking, so as to achieve leakage protection.

Leakage module by the zero sequence current transformers, electronic power amplifier module and electromagnetic release component, and its linkage rod through the small circuit breakers with GSB2 institutions linked trip. When the circuit appears to be the protection of insulation failure of electric shock or personal accident, zero sequence current transformer in one side of the instantaneous current vector and non-zero (IA + IB + IC + IN ≠0 transformer secondary windings will produce induced voltage, the voltage by the electronic power amplifier module to enlarge after the release of the release of electromagnetic coils, when the leakage current setting to achieve the value of the action, the release of electromagnetic pull-in, so that the pull-bar linkage circuit Sub-gate, the main circuit breaking, so as to achieve leakage protection.
Note: The leakage circuit breakers in accordance with the user's request to increase separation of functions and features over-voltage protection
Separation of functions: leakage circuit breakers can be a group of external control circuit to achieve the remote control function products.
Over voltage protection function: When the supply voltage up to 280V ±5% of over-voltage sensing element conduction, incentive trip coil to release action, driven linkage rod, disconnect circuit breakers, the realization of cross lines voltage protection.4.Parameters
