Change Over Panels
Changeover Panels
In the event of a power outage, our changeover panels are designed to transfer the power supply to an emergency backup, either manually or automatically, depending on the application needs. These panels are available from 16A up to 4000A. For more details, submit an inquiry, and one of our design engineers will assist you.
Manual Changeover Panel (MCO)
- Rotary manual switch with a center-off position to enable selection between two different supplies (e.g., mains and backup generator).
- Custom configurations available: steel wall-mounted enclosures with bottom/top cable entry or floor-standing enclosures with crash frames.
- Enclosure material options: rigid rubber, HDPE, and steel.
- 3 or 4 Pole switching: 16A to 2500A, up to 400Vac (AC21/22A) – [11 to 1700 kVA].
Automatic Mains Failure Panel (AMF)
- Automatically switches the load to a backup power supply upon mains failure.
- Monitors primary supply for phase failure, under-voltage, phase imbalance, and neutral shift.
- Automatically signals and switches to a healthy secondary power source (e.g., generator).
Available Options:
- Various enclosure choices.
- Deep-sea electronic programmable control units.
- Self-seeking auxiliary power supplies.
- Traditional timer and relay logic.
- Inhibit return-to-mains selection.
Switching Capacity:
- 4 Pole contactor: up to 800A, 400Vac (AC21/22A) – [to 550 kVA].
- 4 Pole motorized MCCB: up to 1600A, 400Vac (AC21/22A) – [to 1100 kVA].
- 4 Pole motorized ACB: up to 4000A, 400Vac (AC21/22A) – [to 2700 kVA].
Motorized Transfer Switch (MTS)
- Rotary motorized switch with center-off position for automatic supply selection.
- Uses the same switch range as MCO, but equipped with motor operators and a programmable control module.
- Monitors both supplies and signals the standby supply or generator as required.
- 3 or 4 Pole switching: 160A to 1600A, up to 400Vac (AC21/22A) – [110 to 1000 kVA].
- Electronically motorized options available (deep sea and OTM control units).
Auto Transfer Switch (ATS)
- Cost-effective automatic transfer control panel.
- Monitors mains supply and signals the generator or backup supply when failure occurs.
- Automatically switches back to the mains when power is restored.
- Typically housed in proprietary wall-mounted steel enclosures painted to RAL7035.
- Options available: alternative enclosures and custom control configurations (e.g., cool-down timers).
- Single-phase or Three-phase switching: 4 Pole contactor, 32A to 800A (AC21/22A) – [22 to 550 kVA].
