Panel Disconnect Switch
HGL type panel disconnect switch Suitable for AC 50HZ,Website:, rated voltage 400V/690V, rated current 125A, 160A. 3 poles & 4 poles. Different operating modes, can be divided indoor operation and outdoor operation. The contacts are made of copper and the cover is made of flame retardant plastic.Modular DesignOptional micro switchThe terminal is Copper T33-poles or 4-polesAvoid erroneous operationsDesigned according to IEC/ EN 60974-3Conventional current160ARated current In(A)125160Rated insulation voltage Ui (V)1000Dielectric strength (V)8000Rated working currentAC-21B125160380VAC-22B125160AC-23B125160AC-21B125160660VAC-22B125160AC-23B8080Motor power380V6380P (Kw)660V7575Rated short-time withstand current lcw (kA Rms) 0.1s/1s88Rated breaking capability Icn (A Rms) AC23 380 V10001000Rated making capability Icm (A Rms) AC23 380V12501600Rated shortcurrent making capabilityIcm (kA peak value)13.613.6Mechanical durability 380V14001400Electical curability 380V200200Operation moment (Nm)6.56.5Weight (kg)3 poles1.31.34 poles1.51.5For general power transmission operation: firstly panel disconnect switch, and then close the circuit breaker or panel disconnect switch.When the panel disconnect switch is powered off: first disconnect the circuit breaker or load switch, then disconnect the isolating switch.When choosing, it is no different from other electrical equipment. It must be rated voltage, rated current, dynamic steady current, and thermal stable current.The function of the panel disconnect switch is to disconnect the circuit without load current. The device to be repaired has obvious disconnection point from the power source to ensure the safety of the maintenance personnel. The panel disconnect switch has no special arc extinguishing device and cannot cut off the load current and short circuit current. Therefore, the panel disconnect switch must be operated only when the circuit is disconnected from the circuit breaker.
