Which current ratings and poles are available?

KGLD 20–1600A, KGQ2 100–1600A, KGLZ 63–3150A; all series in 3P/4P. Choose 4-pole when neutral switching is required (e.g., generator supplies, sensitive electronics).

How fast is the transfer time?

Electronic ATS (KGLD) typically ≤200 ms. MCCB-type (KGQ2) may be slightly longer due to mechanical operation. Manual type (KGLZ) depends on the operator.

Where should each series be used?

KGLD: hospitals/data centers/telecom mains; KGQ2: commercial & industrial compact panels with high SCCR; KGLZ: generator rooms and distribution maintenance that require visible isolation.

How to coordinate ATS with upstream/downstream protection?

Verify SCCR at the ATS location and pair with suitable upstream fuses/MCCBs for selectivity. KGQ2’s MCCB-type simplifies coordination.

Is ATS compatible with generator systems?

Yes. Interlocks prevent simultaneous ON. KGLD provides controller I/O for genset start/stop and status feedback. Consider 4-pole for generator-supplied systems.

What maintenance is recommended?

Inspect contact wear, interlocks, terminal torque, and controller alarms periodically (6–12 months depending on duty).

Installation & Compliance Guide

General Installation Requirements

Automatic transfer switches must be installed by qualified electricians familiar with local wiring codes. Each Kuangya ATS is delivered with clear terminal markings and installation manuals. Ensure adequate clearance around the switch for cable bending radius, ventilation, and safe operation of the handle or actuator.

Mount ATS vertically inside switchboards or wall-mounted enclosures.
Provide sufficient space for incoming and outgoing cables.
Observe torque values on power terminals to guarantee reliable contact.
Maintain separation between power and control wiring to reduce interference.

Wiring & Connection Practices

Para KGLD dual power ATS, connect the electronic controller to the power supply and signal I/O terminals. Remote monitoring, genset start/stop, and alarm outputs are available. For KGQ2 MCCB type, verify interlock wiring if optional motor mechanism or remote control is used. For KGLZ manual switches, only power conductors are connected, with mechanical interlock ensuring isolation.

Always check phase sequence and neutral connections. In 4-pole versions, the neutral conductor must be wired through the designated neutral terminal of the ATS. Incorrect neutral handling can lead to equipment malfunction or hazardous touch voltages.

Compliance & Standards

Kuangya ATS are designed according to IEC 60947-6-1, covering automatic and manual transfer switches. Products carry CE and RoHS conformity, and can be supplied with factory test reports. For large projects, witness testing and additional certificates (TÜV, CB scheme) can be arranged upon request.

When integrating ATS into low-voltage assemblies, verify that the overall short-circuit rating (SCCR) meets local regulations. Always coordinate ATS with upstream protection (fuses or MCCBs) to comply with IEC and NEC installation rules.

Considerações sobre segurança

During installation and service:

Isolate all sources before working on ATS terminals.
Use appropriate PPE (insulated gloves, arc-rated clothing) according to site safety rules.
Do not bypass mechanical or electrical interlocks.
Check that control power and auxiliary contacts are correctly wired before energizing.

Periodic inspection is recommended every 6–12 months depending on load cycles. Inspect contact wear, interlock operation, and control wiring integrity.

Support & Documentation

Each Kuangya ATS is shipped with a printed manual and QR code for online resources. Additional documents include:

Datasheets with dimensions, ratings, and connection diagrams.
Wiring guides for generator and dual-utility systems.
Certificates of conformity and compliance with IEC/CE standards.
