LT 70A
Build the transfer function around proven switching hardware with the NHP/Socomec LT 70A. Rated at 70A, it suits standby-power switchboards where essential loads need to change between mains and generator supply. Pair it with a compatible controller such as the DSE331, DSE334, DSE335 or another generator controller with mains-failure detection and ATS control. The final assembly must be correctly engineered for current rating, fault level, interlocking and site operating sequence. CPS can assist with controller selection, switchboard design, generator integration, testing and commissioning.
- Safely transfers load between utility and generator supply when integrated into a compliant switchboard
- Designed for backup-power and AMF/changeover applications
- Current rating and pole configuration must match the project design

Almost every conversation about generator sizing starts with two numbers: kVA and kW. They sound similar, they're closely related, and they're almost always mis-used. The beer-glass analogy below is the fastest way to get them straight in your head — and once you do, every spec sheet in the catalogue suddenly makes sense.

A generator is really three machines bolted together: an engine, an alternator, and a controller. They each do one job, and they all have to talk to each other for the unit to behave properly.

Almost every customer who asks us 'should I get diesel or petrol?' gets the same answer: it depends on the duty. For occasional camp / weekend use under 8 kVA, petrol is cheaper to buy and lighter to move. For anything that has to start reliably after sitting unused — backup, standby, prime-power — diesel wins, almost always.
