NSi A560MW – Frequently Asked Questions

1) Will the NSi A560M spring wound timer work on a 277V lighting circuit?
Yes. The A560M is rated 125-250-277 VAC, so it covers standard 120V residential circuits as well as 277V commercial lighting branch circuits. Frequency rating is 50-60 Hz, so it works on North American 60 Hz and 50 Hz systems alike.
2) Does the A560M timer fit a standard single gang box and wall plate?
It mounts in a standard single gang wall plate enclosure, so it drops into the same opening as the switch it is replacing and takes a single gang plate. Confirm your box has the depth for the spring wound mechanism before closing it up.
3) How long will the NSi A560M run before it shuts off?
Up to 60 minutes per twist. It is a spring wound mechanism, so you set the run time by hand and it winds down to off on its own. No programming, no batteries, nothing to lose at a power outage.
4) What does SPDT switching give me on this bath fan timer?
The A560M uses single-pole, double-throw action, so it can transfer a load between two circuits rather than just making and breaking one. In practice that lets you do things a plain SPST timer cannot, such as switching a fan to an alternate feed or driving a second device off the normally-closed leg.
5) Can I use the A560M timer outdoors or in an unheated garage?
Operating range is 32 to 122 F, so freezing conditions are outside its rating. It is an in-wall device for a single gang box and belongs in a conditioned or protected interior location, even when the load it controls is outdoor lighting.
6) Is the NSi A560M timer listed for commercial code-compliant work?
It is cULus listed, which covers both US and Canadian safety listing requirements for an inspected electrical installation.
7) What is the part number difference between the ivory and white A560M timers?
Ivory is MPN A560M and white is A560MW. Same 60-minute spring wound SPDT device either way, the suffix just calls the color so you can match the other devices and plates on the wall.
8) Does replacing a wall switch with the A560M require rewiring?
No rewiring beyond a standard timer swap. It takes the place of the existing switch in the single gang box and uses the same wall plate opening, so for a straight switch-for-timer change the branch circuit stays as it is.
9) What loads is the A560M spring wound timer meant to control?
Whole house fans, bathroom exhaust fans, indoor and outdoor lighting, and self storage area lighting are the intended applications. Anywhere you want a run-and-shut-off on a manual switch leg without a programmable control.
