1SBL177001R1401

The ABB AF16-30-01-14, Product ID 1SBL177001R1401, is a compact industrial 3-pole block contactor from ABB’s AF series, designed for reliable switching of three-phase motors and general industrial loads.

It has 3 normally-open main power contacts and 1 built-in normally-closed auxiliary contact (0 NO + 1 NC). This configuration is useful in motor starters, control circuits and interlocking applications where an NC feedback or control contact is required.

The contactor uses ABB’s wide-range electronic coil technology, operating from 250–500 V AC at 50/60 Hz and 250–500 V DC. The AF electronic coil is designed to handle wide control-voltage variations and includes built-in surge suppression, reducing the need for a separate external coil suppressor.
