Manual and automatic changeover panels
In the event of a power outage, our changeover panels are designed to transfer the supply to an emergency backup supply, either manually or automatically depending on the need of the application. Manufactured from 16A up to and including 4000A. If you require more information, submit an enquiry and one of our design engineers will contact you shortly.
Manual Changeover panel (MCO)
Rotary manual switch with centre off position, to enable selection of 2 different supplies. Most commonly a mains supply and a back-up generator supply.
Configurations can be provided to suit your application, these may include, steel wall mounting enclosure with bottom, and/or top cable entry. Steel floor standing enclosures, mounted within galvanised crash frames. Other enclosure materials are available including rigid rubber and HDPE.
3 or 4 Pole switching from 16Amp to 2500Amp, up to 400Vac. (AC21/22A) – [11 to 1700 kVA].
Automatic Mains failure panel (AMF)
Automatically switches your load to a backup supply in the event of a mains supply failure.
Automatic Mains Failure systems are electrical control panels designed to keep your electrical equipment, (the load), running from a secondary electrical supply should your primary electrical supply fail.
The primary supply, (usually a mains supply), can be monitored for phase failure, under voltage, phase imbalance, phase rotation and neutral shift. Should there be a problem with the primary supply, the AMF panel will signal that the secondary supply, (usually a generator), is required.
This secondary supply is also monitored, and when healthy, switched to feed the load.
Various options are available, these include:
Choice of enclosure types.
Deep sea electronic programmable control units, offering greater flexibility.
Self seeking auxiliary power supplies.
Traditional timer and relay logic.
Inhibit return to mains selection.
4 Pole contactor switching up to 800Amp, 400Vac. (AC21/22A) – [to 550 kVA].
4 Pole motorised MCCB switching up to 1600Amp, 400Vac. (AC21/22A) – [to 1100 kVA].
4 Pole motorised ACB switching up to 4000Amp, 400Vac. (AC21/22A) – [to 2700 kVA].
Motorised Transfer Switch (MTS)
Rotary motorised switch with centre off position, to enable automatic selection of 2 different supplies. Most commonly a mains supply and a back-up generator supply.
Utilising the same range of switches as our MCO range, these are equipped with motor operators and a programmable electronic control module to monitor the condition of both supplies and provide signalling to stand-by supply or generator as required.
3 or 4 Pole switching from 160 to 1600Amp, up to 400Vac. (AC21/22A) – [110 to 1000 kVA].
Can be electronically motorised in the form of deep sea and OTM control units.
As with other changeover systems, a range of enclosure options are available and we are happy to engineer specific application solutions.
Auto Transfer Switch (ATS)
A range of cost effective, value for money automatic transfer control panels, to enable selection of 2 different supplies. Most commonly a mains supply and a back-up generator supply.
Just the mains or supply 1 is monitored, and should this supply fail the ATS will signal to start the generator or supply 2; when available this will be switched to the load.
Should the mains become healthy again, the Auto Transfer Switch will automatically switch back to utilise this supply.
Generally available in proprietary wall mounting steel enclosures painted to RAL7035, we are happy to offer engineered options including alternative enclosures, or control configurations, such as cool down timers.
Single phase or Three phase; 4 Pole contactor switching from 32 to 800Amp, (AC21/22A) [22 to 550 kVA – three phase].
