NewTrend · hum-free modular contactor
Product overview
NewTrend YMC-32/20 is a hum-free modular contactor with two normally-open main contacts in an 18mm-wide DIN-rail body. It is rated 32A for AC-7a / AC-1 loads and 12A for AC-7b / AC-3 loads, at 250VAC for this two-pole version. The factory selection table lists nominal 12V, 24V, 48V, 110V and 230V AC/DC coil versions. This page covers the /20 contact arrangement only.

Operation
- Apply the nominal voltage of the selected AC/DC coil version to terminals A1–A2. The five voltage choices represent separate factory versions.
- Main contacts 1–2 and 3–4 are normally open. Use the AC-7b / AC-3 current rating when selecting applicable motor loads.
- Use a spacer between adjacent contactors when the temperature inside the enclosure is 50–60°C.
Typical applications
- Lighting and resistive-heating control in building distribution boards
- Ventilation, pumps and domestic-type motor loads selected by the AC-7b rating
- Modular DIN-rail load switching controlled by a timer or automation output
