ABB SEMI F47 AF09Z.. AF38Z, AF40…AF750 contactors and NFZ contactor relays

AF09Z ... AF38Z and AF40 ... AF750 contactors, NFZ contactor relays

increase the voltage sag immunity and the uptime of semiconductor

processing equipment without use of specific accessory.

Definitions according to SEMI F47 (1)

SEMIF47 defines the voltage sag immunity required for

semiconductor processing, metrology and automated

test equipment, and on subsystems and components

which are used in the construction of semiconductor

processing equipment including but not limited to:

• Power supplies

• Generators

• Robots and factory interface

• Chillers, pumps, blowers

• AC operated contactors and contactor relays

• ...

Voltage sag immunity

The ability of equipment to withstand momentary

electrical power interruptions or sags.

Voltage sag

An rms reduction in the AC voltage, at the power

frequency, for durations from a half cycle to a few

seconds. The IEC terminology for this phenomenon

is voltage dip.

Characteristics

• AF09Z…AF38Z, AF40…AF750 contactors and NFZ

contactor relays are compliant to SEMI F47 (1)

and withstand voltage sags for :

- required voltage sag immunity 

- recommended voltage sag immunity (≤ 20 ms)

• Conditions of use: - rated control circuit voltages between 24 V to

500 V AC 50 / 60 Hz (see selection table)

- air ambient temperature -20°C ≤ Ɵ ≤ +60°C 

- 1-stack and factory-mounted 2-stack contactors

(2 stack contactors as AF..-30-11-.., AF..-30-22-..) 

- 1-stack and 2-stack contactor relays- no additional accessories.

(1) AF09Z…AF38Z and AF40…AF370 are compliant with SEMI

F47-0706. AF400…AF750 are compliant with SEMI F47-0200.
