CX3 power contactors are offered in 16 A, 25 A, 40 A and 63 A ratings with 1 to 3 module widths. Coil voltages are 24 V AC and 230 V AC (and 230 V AC low-noise for 16/25 A). Conditional short-circuit current is 6 kA for 16-25 A and 3 kA for 40-63 A when protected by a circuit breaker or gG fuse not exceeding the contactor rating. Spacing modules are recommended between contactors to manage heating.
