Uninterrupted Power Switch

TOMZN 4P AC ATS Features

• Automatic Dual-Power Switching – Seamlessly transfers electrical load between two power sources (e.g., grid and backup generator/inverter) for continuous power without user action.

• Fast Switching Time – Quickly changes over in less than 50 ms, minimizing disruption to connected equipment.

• 4-Pole 3-Phase Design – Handles all three phases plus neutral, ensuring balanced and complete switching for three-phase systems.

• Multiple Current Ratings (63A/100A/125A) – Available in different rated current options to suit a range of load requirements.

• High Surge Withstand (8 kV) – Built-in impulse withstand protects against transient voltage spikes during switching events.

• PC-Level Reliability Construction – Designed for stable automatic switching without generating dangerous short-circuit currents, protecting circuits and appliances.

• Wide Operating Range – Works reliably within ≈85 % to 110 % of rated voltage, accommodating minor voltage variations in supply.

• DIN-Rail Mountable – Standard DIN-rail installation makes it easy to mount in electrical panels and distribution boards.

• Durable Mechanical & Electrical Life – Built to last thousands of automatic switching cycles for long-term use.
