NSi A560MHW – Frequently Asked Questions

1) Will the NSi A560MHW spring wound timer work on a 277V lighting circuit?
Yes. The NSi A560MHW in-wall spring wound timer carries a 125-250-277 VAC contact rating at 50-60 Hz, so it can switch 120V residential circuits and 277V commercial lighting branch circuits alike. That makes it usable in a light commercial corridor or storage building running 277V as well as a house bathroom fan on 120V.
2) Does this NSi 60-minute timer fit a standard single gang box and wall plate?
It mounts to a single gang wall plate and is built as a single gang enclosure, so it drops into a standard single gang opening in place of a toggle switch. Use a standard single gang plate; the timer itself is white to match common device plates.
3) Can I use this NSi timer for an exterior light or an unheated storage building?
Its rated operating temperature range is 32 to 122 F. It will control outdoor lighting, and NSi lists outdoor lighting and self storage control among the intended applications, but the timer itself has to live in a space that does not drop below freezing. A device in an unheated building in a cold climate falls outside that range.
4) What does the hold feature on this spring wound timer actually do?
Twisting past the timed range into the hold position keeps the load running continuously instead of counting down. That is how you leave a bathroom fan or a storage area light on indefinitely, then twist back to the 60 minute dial range when you want it to shut itself off. Without hold, the switch always times out.
5) Why is this timer SPDT instead of a simple on/off, and what does that let me wire?
The A560MHW switches SPDT, single pole double throw, so it has a common plus two switched outputs rather than one. That lets you transfer a circuit between two loads, or energize one path while the timer runs and the other when it times out, instead of only making and breaking a single leg. For a plain fan or light you simply use the common and one of the throws.
6) Is the NSi A560MHW timer listed for commercial work?
It is cULus listed, which covers both US and Canadian installations for inspection purposes. Combined with the 125-250-277 VAC rating, it is used in residential and light commercial wiring.
7) Is a spring wound timer or an electronic timer switch the better choice for bathroom fans?
A spring wound unit like the A560MHW is fully mechanical, so it needs no neutral and no battery, and it cannot lose its setting in a power outage. You twist the dial and it winds down. The tradeoff is a fixed 60 minute maximum range and audible mechanical operation. An electronic countdown timer gives you preset button intervals and longer durations, but typically requires a neutral in the box. For multifamily and self storage fleets where tenants break things and nobody resets settings, the spring wound version is the simpler standardization.
8) What is the exact part number to order this NSi 60-minute timer with hold in white?
Order NSi Industries A560MHW. It is the 60 minute spring wound in-wall time switch with hold, SPDT, white. One configuration only, so there is no finish or voltage option to specify.
