Overview

The NSI Industries A515MW is a white, in-wall mechanical interval timer designed for precise control of timed circuits in residential and commercial applications. This model offers a maximum 15-minute ON time, activated by a simple twist of the knob, with an automatic 'No Hold' function that ensures the circuit turns off after the set interval. Ideal for whole house fans, lighting, bathroom fans, and self-storage units, the A515MW simplifies installation with its 'Easy Wiring' feature, eliminating the need for a neutral wire—perfect for retrofit scenarios. The 'Easy-Set' mechanism requires no post-wiring adjustments, and the SPST '2 in 1' contacts allow flexible wiring as either normally on or countdown while off. Compatible with standard or decorator wall plates (not included), it supports single or multi-gang installations without de-rating. Operating at 125/250/277VAC, 50/60Hz, the timer handles resistive loads up to 20A (125V), 10A (250/277V), inductive loads up to 20A (125V), 10A (250/277V), and motor loads up to 1HP (125V) or 2HP (250V). With a terminal range of #12AWG and an operating temperature range of 32°F to 122°F (0°C to +50°C), the A515MW is built for reliability in diverse environments.
