The system for dual power change-over switch HQ1 is designed to provide continuous power supply and two electrical souces automatic switch in case of failure or deviation from the set parameters. The sysytem for dual power change-over switch consists of two high capacity circuit breakers mounted on a metal frame connected with common operating mechanism and controlled by a command devices that controls the system parameters’correspondence. Functions * Swithcing on/off heavy loaded electrical circuits at main power supply discrepancy * Switching to dual power change-over at power supply phase lack * Breaking of electrical circuits and control of powerful consumers * Used as a main breaker in housing or industrial distributing installations supplied with a generator or a second power supply source (hospitals ,post office,miliary sites,control rooms) * Remarkable with high reliability of current characteristics * Control:motor * Controls the following circuit parameters - presence of the three phases - the phase voltage to be in the set limits - overload - short circuit at the outlet Technical date * Rated operating voltage:690V.50/60Hz * Surge voltage wear resistance:8000V * Joining termainal:bolt connection with 4 bolts to the power supply rail * Connecting: - copper rails - flexible or rigid conductors * Electrical wear resistance(number of cyles):10000 * Mechanical wear resistance(number of cyles):20000 * IP code:IP21 * Mounting: - clamping with bolts - mounting position:vertical gradient-maximum 5o * Plastic material of the breakers of UV rays and non-flammable * Ambient temperature:-10℃+45℃ * Installation altitude:up to 2000m basic functions of the control device * Overload protection * Instantaneous short circuit protection * Under phase protection * Possibility for setting the change-over time between the two sources -min 3s * Possibility for automatic switch-over to the main power supply source after restoring its parameters The sysytem for dual power change-over switch is offered in two types: - with display(control device)mounted on the mounting plate(integrated type) - with separated control dispaly Dimensions Type of the breaker Dimensions(mm) A B C D H inner type HQ1-100 480 240 450 210 140 HQ1-225 480 240 450 210 140 HQ1-400 620 300 590 270 235 HQ1-630 660 300 630 270 240 moved type HQ1-100 420 230 390 200 145 HQ1-225 420 230 390 200 145 HQ1-400 570 300 540 270 235 HQ1-630 610 300 580 270 240 Type Rated current ln(A) Max.breaking capacity (kA)lcu Oerating breaking capacity (kA)lcs Section of the power supply conductor (mm2) Electrical wear resistance (number of cycles) package/box (pcs) HQ1-100 100 22 15 35 6000 1/1 HQ1-225 225 35 25 70 6000 1/1 HQ1-400 400 42 35 180 6000 1/1 HQ1-630 630 50 42 240 6000 1/1   HQ1-100＊ 100 22 15 35 6000 1/1 HQ1-225＊ 225 35 25 70 6000 1/1 HQ1-400＊ 400 42 35 180 6000 1/1 HQ1-630＊ 630 50 42 240 6000 1/1
