Eaton 伊顿 EGF2SPDTNE100 接地电阻测试仪

"The CurrentWatch EGF Series from Eaton’s electrical business is a family of ground fault (earth leakage) sensors. Ground fault sensors help protect people, products and processes from damage by ground fault conditions by monitoring all current-carrying conductors in grounded single- and three-phase delta or wye systems. The EGF Series is available with either solid-state or mechanical relay outputs.","The EGF Series with solid-state outputs offers the benefit of reliable, long-lasting solid-state switches. Solid-state design provides unlimited switch operating life, superior resistance to shock and vibration, zero off-state leakage, high switch speeds and high input-output isolation. Solid-state outputs have solidcore housings with screw terminals.","The EGF Series with mechanical relay outputs are available in solidcore housings with a choice of N.O. or N.C. SPST latching relays and a SPDT Form C relay with auto-reset. All mechanical models can be ordered with a fixed setpoint or with a triset option, which provides three factory-set, field-adjustable setpoints."
