Contactor 24-60V AC, 20-60V DC AF16-30-10-11 1SBL177001R1110

Universal contactor for controlling motors and circuits

This three-pole AF16-30-10-11 contactor is a reliable solution for controlling electrical circuits, especially in applications involving three-phase motors, non-inductive loads, and low-inductive circuits. Its versatility stems from the ability to be powered by both alternating current (AC) and direct current (DC), making it an ideal choice for a wide range of industrial and commercial applications. The contactor's design is enhanced with a built-in surge suppressor, increasing its durability and resistance to interference.

This contactor stands out with a wide range of control voltages – from 24 to 60V AC and 20 to 60V DC – supported by only four types of coils. This simplifies component selection and reduces storage costs, which is particularly important for installers undertaking large-scale projects. The use of an electronically controlled coil ensures stable operation and minimizes noise levels during switching.

Characteristics and application

The AF16-30-10-11 contactor is designed to operate in circuits with a voltage of up to 690V AC and 220V DC. The rated operating power for AC-3 is 7.5 kW at 400V, and the rated operating current Ie is 18A for AC-3 at the same voltage. This makes the contactor perfectly suited for applications requiring frequent switching of motors, such as ventilation systems, pumps, conveyors, or production machines. The ability to mount on a TH rail and the screw connection of the main contacts facilitate installation and maintenance.

The contactor design includes one normally open auxiliary contact (1NO) and three normally open main contacts (3NO), allowing for flexible configuration of control circuits. Compact dimensions (86 mm high, 77 mm deep and 45 mm wide) allow for mounting in tight switchgear spaces. The IP20 degree of protection provides basic protection against accidental contact and the ingress of solid objects.

Advantages and benefits
