ONLY PV System Power Transfer to City Power (SPECIAL USE)
NLQ4 series dual power automatic transfer switch is new developed micro household power transfer switch.. The switch is mainly used for testing whether normal or spare power is normal or not. When the normal power is abnormal, the spare power works at once, which therefore ensures the continuirty, reliability, and safety of power supply. The product is specially designed for household orbit-type installation and specially use in PZ30 power distribution box.
NLQ4 series automatic transfer switch is suitable for the emergency power supply system with 50 or 60 Hz alternatting current rated 400V 60A. TSE is compact in structure, reliable in transfer, convenient in instabllation and maintenance, and has long lif expectancy. Widely used In various occasions where continuous power failure ls not allowed, it can be operated both electrically and manually.
ATSE is composed of TSE and the controller. ATSE compiles with requirements of Low-voltage Switch Gear and Control Gear specified by GB/T14048. 11, Part 6-1 : Multiple functional equipment and transfer switch equipment.

Frequently Asked Technical Questions & Selection Guide
Pure engineering specifications, tripping curve parameters, and electrical selection guidance for panel builders and system designers.
How to verify rated operational voltage, frequency, and load duty cycle?
Verify that the nominal line voltage (AC 230V single-phase or 400V/415V/690V three-phase at 50/60Hz, or DC voltage ratings) falls within the continuous maximum operating limits of the device. Check duty cycle ratings (continuous vs intermittent duty) to ensure thermal stability under full load.
What ingress protection (IP Rating) and environmental enclosures are recommended?
For clean indoor electrical rooms, standard IP20 modular DIN-rail housings are recommended. For outdoor, industrial washdown, or dusty environments, mount components inside weatherproof enclosures rated IP65/IP66 with UV-resistant polycarbonate or powder-coated steel enclosures equipped with compression cable glands.
How to ensure upstream and downstream coordination in power distribution boards?
Ensure proper discrimination by grading current thresholds and tripping time delays: upstream devices should have higher current ratings and intentional short-time delays (Class S), allowing downstream branch MCBs to clear localized faults without blacking out the entire facility.
What mounting rails, busbars, and spatial clearances are required?
Components mount on standard symmetrical 35mm DIN rail (EN 60715 / TH35-7.5) or backplate screw fixings. Maintain recommended top/bottom ventilation gaps (typically 30–50mm) to ensure unrestricted air convection, and use standard pin/fork comb busbars to minimize contact resistance and wiring errors.
What conductor sizes and terminal tightening torques should be applied?
Select copper or aluminum conductor cross-sections complying with IEC 60364-5-52 current-carrying capacity tables based on continuous load. Always use a calibrated torque screwdriver or torque wrench to tighten terminal screws to the manufacturer-specified torque to prevent hot-spot degradation and loose connections.
