AC Contactors, Thermal Overload Relays and Motor Starters
The most expensive mistake in this category is not the price, it is the coil. A 50 Hz coil energised on a 60 Hz supply runs hot, hums and fails to hold reliably; the reverse over-currents the coil. Voltage alone does not tell you this — frequency does.
Ranges
NXC / NC1 — AC-1 and AC-3 power contactors
CJX2 / NCH8 — widely stocked legacy and installation types
NR2 — thermal overload relays, manual and auto reset
NS2 — combination motor starters (NP2 + NR2)
Auxiliary contact blocks, mechanical interlocks, delay units
Every quotation line states four things
Field
Why it matters
Rated operational current Ie and utilisation category (AC-3 / AC-1)
Motor duty and resistive duty are different ratings
Coil voltage
24 / 48 / 110 / 220 / 380 V
Coil frequency (50 Hz / 50–60 Hz)
The failure mode described above
Accessory set
Aux contacts and interlocks quoted separately, never hidden
If you are buying for Saudi Arabia or Peru — 60 Hz grids — say so in the first message. We will confirm which coil codes are available rather than shipping the 50 Hz stock we already paid for.
Get a Real Quotation, Not a Brochure
Send: model or photo · quantity · destination country · grid (V / Hz / 1φ or 3φ) · required certificate. You get unit price, packing data (carton / pcs / GW / CBM), lead time and the certificate list in one message, within 24 hours. If we cannot supply a code or a certificate you need, that first message says so.
