ABB AF26-30-00-11 1SBL237001R1100 Product Description

Overview

ABB AF26-30-00-11 1SBL237001R1100 is an AF26 series 3-pole IEC contactor with screw terminals and three NO main contacts. The ABB catalog identifies it with control voltage 24 to 60 V 50/60 Hz AC and 20 to 60 V DC, main-circuit rated operational voltage up to 690 V AC, AC-3 motor rating 11 kW at 400 V, and 3-phase UL motor rating 15 hp at 480 V. It is a legacy motor starter or power switching contactor spare for existing industrial control panels.

Features

The contactor has three main NO contacts and no fitted auxiliary contacts in the base order code. Main contacts are 3 NO; main NC contacts are 0; auxiliary NO contacts are 0; auxiliary NC contacts are 0. The AF electronic coil interface provides a wide control-voltage range and reduced pull-in and holding consumption, with built-in surge protection according to the ABB datasheet.

Main-circuit conventional free-air thermal current I_th is 50 A for an open contactor at 40 °C. AC-1 rated operational current is 45 A at 690 V and 40 °C, 40 A at 60 °C, and 32 A at 70 °C. AC-3 rated operational current is 26 A at 220 to 240 V, 380 to 400 V, 415 V and 440 V; 23 A at 500 V; and 17 A at 690 V. The DC-1 rating uses poles in series for 110 V or 220 V applications as listed in the catalog record.

Rated impulse withstand voltage is 6 kV. Maximum electrical switching frequency is 600 cycles per hour for AC-1, 150 cycles per hour for AC-2 or AC-4, and 1200 cycles per hour for AC-3. Maximum mechanical switching frequency is 3600 cycles per hour. Power loss at rated operating conditions is 1.8 W per pole for AC-1 and 0.6 W per pole for AC-3.

Principle

The contactor switches a three-phase motor or power load by closing or opening its three main NO contacts when the coil is energized or de-energized. The AF electronic coil interface accepts the specified AC or DC control voltage range and reduces coil pull-in and holding consumption. When coil voltage is applied, the main contacts close according to the listed operate time; when coil voltage is removed, the contacts open and the motor or load is disconnected.

The base AF26-30-00-11 has no built-in auxiliary contacts, but AF contactors can use compatible add-on or front-mounted auxiliary contact blocks, side-mounted blocks, mechanical interlocks or electrical interlocks according to the AF09 to AF38 accessory range. Replacement should verify coil control voltage AC or DC, pole count, NO or NC contact configuration, motor power, AC-1 or AC-3 duty, load current, terminal wiring, auxiliary contact requirement, DIN rail or screw mounting, interlock use, phase sequence, short-circuit protection and control-circuit fuse or PLC output capacity.

ABB notes the AF26-30-00-11 is not suitable for direct control by a PLC output in the datasheet note. Coil polarity, if applicable, and terminal marking should be checked against the original wiring diagram and ABB manual before commissioning.

Applications

ABB AF26-30-00-11 1SBL237001R1100 is used for three-phase motor control, pump and fan starters, compressor starters, conveyor drives, machine tool contactors, packaging machinery, HVAC control panels, material handling, non-inductive or slightly inductive power loads and general industrial load switching. In legacy installations, it serves as a direct replacement contactor spare when the coil voltage, contact configuration, motor rating, load current, mounting, terminal capacity and auxiliary requirement match the original AF26 unit.
