HN Series 9A 220-230V/50-60HZ Contactor
Frequently Asked Questions
What's the difference between this and the 1NO auxiliary version?
This variant has a normally-closed (N.C.) auxiliary contact, useful for fault/status signalling that needs to open when the contactor energises. If you need a normally-open auxiliary for a start/run signal, EMAS also offers the 1NO version of this contactor.
Is 9A enough for my motor or heating load?
9A/4KW is rated for motor loads; for resistive heating loads, the AC1 thermal rating goes up to 20A. Check the load's nameplate current against these ratings before selecting.
Can this replace my existing branded contactor?
Likely yes — this is a common form-factor replacement for major contactor brands. Confirm your coil voltage and pole/auxiliary configuration match before ordering.
Is it suitable for a washdown or outdoor panel?
No — IP20 rated, intended for mounting inside an enclosed control panel rather than direct exposure.

- Heating & process control — switching heating elements and resistive loads up to 20A
- Motor control panels — 9A/4KW motor starter for pumps, fans, and small industrial motors
- Lighting control — contactor switching for large lighting loads in commercial or industrial buildings
