ABB AF16-30-22-12 Contactors 1SBL177001R1222 AC/DC Operated Screw Terminals

AF16-30-22-12 is usually the contactor model of ABB brand. The following is a detailed introduction to its possible technical parameters:

1. Main circuit parameters

Rated working current: "30" in the model means that the rated working current of the main contact of the contactor is 30A. This means that under the specified working conditions, the main contact can stably carry 30A current for a long time and can be used to control loads of corresponding power, such as small motors.

Rated insulation voltage: The general rated insulation voltage is 690V, which indicates that the main circuit part of the contactor can ensure good insulation performance in a voltage environment of 690V and below, prevent leakage and short circuit, and ensure safe use.

Rated working voltage: Common specifications are 230V, 400V, 690V, etc. Different rated working voltages are suitable for different power systems and application scenarios, and need to be selected according to actual circuit requirements.

2. Auxiliary contact parameters

Contact configuration: In "22 - 12", "22" means there are 2 normally open auxiliary contacts and 2 normally closed auxiliary contacts. Normally open auxiliary contacts are in an open state when the contactor is not energized, and are closed after energization; the normally closed auxiliary contacts are the opposite. "12" may be a specific auxiliary contact combination identifier, which is used to distinguish different functions or connection methods.

Rated thermal current: The rated thermal current of the auxiliary contact is usually 6A, that is, under normal working conditions, the auxiliary contact can continuously carry 6A current without being damaged by overheating.

Rated control capacity:

For AC-1 usage category (non-inductive or slightly inductive load), the rated control capacity of the auxiliary contact can generally reach 230V, 5A.

For DC-12 usage category (resistive load), it can reach 24V, 5A. This specifies the voltage and current range that the auxiliary contact can reliably control under different load types.
