Learn more by watching our Cabac HNS446TM | Minute Timer S-Premium 3-Wire 240V 5A video.
The Cabac HNS446TM is a 3-wire minute timer switch rated 240V 50Hz with a 5A relay for timing fans, motors, and commercial lighting circuits. It delivers adjustable delay times from 1 to 30 minutes in one-minute increments and fits Clipsal Saturn and Saturn Zen wall plates. The HNS446TM is part of the S-Premium range, engineered in Australia for Saturn wall plate compatibility.
The HNS446TM solves the problem of leaving fan motors and exhaust circuits running indefinitely. Licensed electricians specify this timer for bathroom and kitchen exhaust fans, ensuring timed shutoff without manual intervention. A blue LED indicator provides visual feedback and flashes in the final 10 seconds before timeout, making the timer transparent on site. Unlike market-leading competitors, the HNS446TM offers 3-wire timing capability, which means it can drive fan motors, transformers, and high-current loads that 2-wire timers cannot support.
Electricians value the S-Premium range for its integration with Saturn wall plates, which are increasingly specified on modern residential and commercial fitouts. The HNS446TM's relay switching design accommodates wire-wound transformers and motors where ordinary timers fail. Its retained settings after power loss ensure the timer restarts with the same programmed time, reducing service calls. The range fills a gap: competitors do not offer 3-wire timers, making the HNS446TM a unique specification for fan and motor control on Saturn wall plates.
The Cabac HNS446TM is not suitable for circuits requiring instant-off switching without delay; it is designed for timed operation only. The HNS446TM cannot be used as a standalone light dimmer; for dimming applications, use the S-Premium Digital Dimmer range. The timer must be installed by a licensed electrician in accordance with AS/NZS 3000 and local building codes. The HNS446TM is a timing mechanism and does not provide RCD or MCB protection; it must be protected by appropriate circuit protection upstream.
(HNS446TM)
The HNS446TM uses a relay to switch loads, allowing it to drive fan motors, wire-wound transformers, and high-inrush-current loads. 2-wire timers cannot handle these inductive loads safely. The HNS446TM is the only 3-wire minute timer available from the market-leading manufacturer's competitors; it fills a critical gap for motor and transformer timing.
Yes. The HNS446TM is installed in the circuit feeding the exhaust fan motor. Licensed installation is required. Typical wiring uses a wall-mounted pushbutton (the timer mechanism) controlling power to the fan circuit; when activated, the timer runs the fan for the programmed delay (1–30 minutes) and then cuts power automatically.
Press and hold the button for 10 seconds to enter programming mode. Release. Then tap the button once for each minute of desired delay (up to 30 minutes). For example, tap 5 times for 5 minutes, 15 times for 15 minutes. The setting is retained after power loss.
Yes. The HNS446TM mechanism fits directly into Clipsal Saturn and Saturn Zen wall plates without additional mounting hardware. The mechanism replaces the existing switch mechanism inside the plate. Installation requires shutting off the circuit at the MCB, removing the old mechanism, and installing the HNS446TM.
The HNS446TM is rated to switch up to 1200W at 240V, equivalent to a 5A load. Common fan motors (0.5–2 kW exhaust fans) fall within this range. For loads approaching 1200W, confirm motor current draw with the manufacturer datasheet before installation.
The Cabac HNS446TM is available online from Sparky Direct, with Australia-wide delivery to any state or territory including regional areas. Sparky Direct is an Australian electrical wholesaler established in 2005, supplying more than 500,000 customers with transparent trade pricing.
