Power Contactor Eti-Polam CEM18.10-230V-50/60Hz 18A 3P 230V AC 1 NO 0R

The Power Contactor Eti-Polam CEM18.10-230V-50/60Hz 18A 3P 230V AC 1 NO 0R is a compact three-pole contactor intended for switching 230 V AC circuits. It features a coil rated for 230 V at 50/60 Hz and a rated switching current of 18 A. The unit provides one normally open main contact and a straightforward design suitable for installation in industrial and commercial electrical panels where space and reliable low-current switching are required.

Advantages

The contactor offers compact dimensions and a clear three-pole switching arrangement that simplifies wiring for single-phase and three-phase control circuits. A 230 V AC coil compatible with both 50 Hz and 60 Hz mains ensures broad applicability. The 18 A rated current and single normally open contact make the device suitable for direct control of smaller motors, resistive loads and lighting circuits while maintaining predictable operation and easy mounting in standard panel assemblies.

Suitable for

• Switching and control of small motors and motor starters
• Control of heaters and resistive loads in commercial installations
• Lighting circuits and auxiliary load switching in distribution panels
• Applications requiring compact, DIN-rail mounted contactors for space-constrained panels

Key specifications

• Number of poles: 3
• Rated operational voltage: 230 V AC
• Coil voltage and frequency: 230 V AC, 50/60 Hz
• Rated current: 18 A
• Contact arrangement: 1 normally open (1 NO)
• Mounting type: panel or DIN-rail compatible compact housing

How to use

Install the contactor in an appropriate electrical enclosure or on a DIN rail according to local electrical codes. Ensure supply and control wiring are de-energized before connecting. Connect the incoming 230 V AC supply to the designated coil terminals and route load conductors through the three main poles maintaining correct phase orientation. Use suitable auxiliary protection devices such as circuit breakers or fuses sized for the 18 A rated current and expected inrush when switching motors. After wiring, apply control voltage to the coil to verify correct operation and contact closure.

Usage recommendations

Choose protective devices and wiring cross-sections consistent with the load characteristics and local regulations. For motor control, consider thermal and overload protection sized to motor starting current. Verify ambient temperature and mounting conditions to ensure reliable long-term operation of the contactor.
