FAQ
-
What is an installation contactor used for?
A contactor switches a circuit remotely or automatically in response to a control signal — commonly used for lighting, heating, or HVAC loads controlled by a time switch, sensor, or building management system, rather than a manual switch.
-
How many poles do I need?
This is a 4-pole, 40A unit. Match the pole count to the circuit being switched — three-phase loads need the corresponding pole count.
-
Can I install this myself?
No — a contactor is wired into a distribution board alongside its control circuit and must be installed by a licensed electrician.
-
Can this be paired with a time switch?
Yes — pairing a contactor with a Hager time switch (e.g. the EHN range) is a common way to give a manually-rated circuit automated, scheduled control without exceeding the time switch's own contact rating.
