1. Application:
Mainly the transfer switch can be used as circuit control switch, test equipment switch, motor control switch and main command control switch, and transfer switch for electric welding machine, etc.The transfer switch is generally used for converting electrical control lines and electrical measuring instruments in AC 50HZ, DC 220V and below circuits with voltage up to 380V and below.For example, XHQ4-125/4P 125A conversion switches are commonly used to convert and measure three-phase voltages.The combination switch is suitable for AC 50HZ, voltage up to 380V and below, DC voltage up to 220V and below. It is used to manually switch on or off the circuit infrequently, replace the power supply or load, and the carrying current is generally large.
2. Features:
A. Small size but high switching capacity.
B. Built-in high performance MCU provides precise transfer power supply.
C. Energy-saving, driven by instantaneous impulse coil.
D. Cost-effective, improved circuit design consumes very low power.
E. Flame retardant cover provides good fire, heat and weather resistance.
F. Withstand the impact voltage: 1KV.

XHQ4-125/4P 125A Switch low voltage switches with multiple circuits.Multiple moving contacts are overlapped on the shaft. When the shaft rotates, moving contacts are connected or broken with static contacts in turn to switch circuits.An electrical appliance that changes a circuit from one set of connections to another.
4. Testing Items:
Accelerated aging test;
Inductive Voltage Test, DC Resistance Test, Safety Test etc.
5. Operating Instruction:
1. Working Conditions:
A. Ambient air temperature: -5oC~+40oC, the highest monthly mean temperature should not exceed +35oC;
B. Altitude for installing place should not exceed 2000m;
C. Atmospheric relative humidity: + 40 not more than 50%, the highest humidity is 90%, air relative humidity of 85% or less;
D. Pollution level: level 2;
E: Use category: AC-22A;
F: Installation: install rail with TH35-7.5 profile steel, shall not exceed 5 degrees of vertical inclination.
2. Quality Assurance of Dual power automatic transfer switch:
A. The main materials used in our change over switch are the high speed, tiny chip and low power consumption CPU as its' center processor inside and assembling with magnetic latching relay as its' main circuit and produced in a high standard of modularized design.
B. The protector will automatically connect circuits as designed time when its' voltage recovery to normal and ensures the terminal equipment runs well under unmanned operation mode.
C. The green indicator LED display lights when the power returns to normal and the red indicator LED display lights when the power is over, under normal voltage range or in delayed conditions.
3. Matters Need Attention:
A. This protector does not have overcurrent protection or short circuit protection, so it shall be installed in front of the protector with overcurrent protection and short circuit breaker;
B. When the protector is disconnected, the relay inside just cuts off L fire line, but N zero line is not broken, so L fire line and N zero line shall not be misconnected when it's in application;
C. Tighten the thread screw when assembling on unit for preventing damage to the product due to poor contact.
4. Why choose us:
A. We are reliable Alibaba Gold Supplier.
B. We are leading manufacturer in voltage protectors for more than 5 years' experience.
C. Rich experience in Global market, export to more than 50 countries.
D. 100% QC inspection before shipment.
E. Keep research and development the latest technology.
F. Reply within 24 hours.
