ZTG Automatic transfer switch

ZTX ATS basic characteristics:

• Operating current: 40 to 3000 А;
• Voltage: 120-600 V;
• Two types of switches: standard switching (ZTG model) and switching with delay in the neutral position (ZTGD model);
• Voltage of disconnecting from the main source: 75 % - 98 % of rated voltage (setting step - 1 %);
• Voltage of the main source recovery: 85 % - 100 % of rated voltage (setting step - 1 %);
• Mains frequency threshold for disconnecting the main source: 88% - 98 % of rated frequency;
• Mains frequency threshold for the main source recovery: 90 % - 100 % of rated frequency;
• Time delay for generator start-up: 0 s to 10 s (setting step - 1 s);
• Time delay for generator warm-up: 0 to 5 min (setting step - 1 s);
• Time delay of switch in the neutral position during switching to stand-by source and back switching to main source: 0 to 10 min with 1 s setting step (for ZTGD model);
• Time delay of switching from the emergency mode: 0 to 60 min (setting step - 1 s);
• Time delay for cooling the generator: 0 to 60 min (setting step - 1 s).
