GHISALBA GHOPC‑410 B AAV66870

Main‑contact Rated Operational Current: 410 A Rated Operational Voltage: 230 VAC Mounting Method: DIN‑rail mounting or bolt‑fixed mounting Certification: CE certification Single‑unit Weight: Approximately 1 kg

Functional Features:

Silver‑alloy thickened low‑resistance contacts, low heating during long‑term continuous conduction. Integrated rectifier coil eliminates external rectifier‑module requirement. Built‑in surge‑absorption circuit suppresses coil reverse‑voltage spike. Anti‑vibration sealed electromagnetic‑actuator structure resists vibration‑environment jitter. Designed for continuous‑conduction bypass‑working condition, single‑pole independent‑unit structure, supports phase‑by‑phase replacement during maintenance.

Application Scenarios:

Large‑power‑motor soft‑starter complete‑sets, fan‑and‑pump motor control cabinets, air‑compressor soft‑start systems, metallurgical‑crusher‑and‑belt‑conveyor‑motor control, central‑air‑conditioning‑chiller‑motor soft‑start cabinets.

Working Principle:

After soft‑start procedure completes, coil obtains rated‑voltage to pull‑in electromagnetic‑mechanism. Main silver‑alloy contacts close to bypass soft‑starter thyristor‑modules. Motor‑load current flows through contactor contacts directly, reducing thyristor‑module heating and eliminating harmonic‑disturbance generated by thyristor‑conduction.

Material Composition:

High‑conductivity silver‑alloy contact material, metal‑magnetic‑core electromagnetic‑coil assembly, engineering‑plastic insulating housing, metal mounting‑bracket, copper high‑current‑conducting bus‑bar.

Structural Characteristics:

Single‑pole independent‑body structure, integrated coil‑rectifier‑and‑surge‑absorption inside housing, metal mounting‑bracket supports bolt‑fixing and DIN‑rail installation, external coil‑wiring plug‑in connector, high‑current main‑terminal bolt‑connection terminals.

Installation Requirements:

Mount inside soft‑starter cabinet, keep sufficient heat‑dissipation clearance around contactor. Torque main‑circuit‑terminals to specified torque‑value to prevent over‑heating. Wiring‑polarity for DC coil must conform to specification. Three‑phase application needs three‑units for three‑phase matching.

Usage Notes:

This component is only suitable for long‑term steady‑state bypass‑conduction. It cannot directly break short‑circuit‑current or heavy‑breaking‑load. Do not use as general‑purpose AC‑3 motor‑contactor. Regularly inspect main‑terminal‑connection‑tightness and contact‑heating condition.
