EMAS HN Series Contactor
AC3 Rated - inductive loads i.e. three phase motors. AC3 ratings are always lower.
Frequently Asked Questions
What's the difference between AC1 and AC3 ratings?
AC1 applies to resistive loads (like heating elements) and gives a higher current rating. AC3 applies to inductive loads (like three-phase motors) and is always a lower rating, since motor inrush current is more demanding on contacts. Check which rating matches your load type before sizing.
Can this replace my existing branded contactor?
Likely yes — this is a common form-factor replacement for Crompton, Schneider, Telemecanique, ABB, and similar branded contactors. Confirm your coil voltage and pole/auxiliary configuration match before ordering.
Is this IP65 rated like the CP series switches?
No — contactors are IP20 rated, intended for mounting inside an enclosed control panel rather than direct outdoor or washdown exposure.
Can I add overloads or extra auxiliary contacts?
Yes — overloads, additional auxiliary contact blocks, and other coil voltage options are available on request.
Industry Applications
- Heating & process control — switching heating elements and resistive loads (AC1 rating)
- Motor control panels — three-phase motor starters for pumps, fans, and general industrial motors (AC3 rating)
- Panel refurbishment — drop-in replacement for aging or discontinued branded contactors
