Overview

The ABB VB6A-30-10-84 is a 3-pole mini reversing contactor designed for precise control of three-phase motor loads up to 4 kW (AC-3) and resistive loads up to 12 A (AC-1) at 400V. Part of ABB's VB6A series, this compact unit is optimized for space-constrained applications in residential, commercial, and industrial environments where reliability and safety are critical. The VB6A-30-10-84 integrates a built-in mechanical interlock and safety blocking function to prevent dangerous simultaneous energization of opposing contactors, ensuring operational safety even in high-risk scenarios. This safety blocking function is triggered if voltage is applied to the coil of the contactor to be switched on before the contactor to be switched off has dropped out. The contactor coils are designed for continuous operation even when the mechanical interlock prevents switch-on, preventing coil damage. Key specifications include a low-consumption AC-operated control circuit (3.5 VA at pull-in and holding), hum-free operation for silent performance, and switch position indication for clear status visibility. The unit supports both DIN rail and wall mounting, offering flexible installation options. Screw terminals ensure secure electrical connections, while the integrated auxiliary contact (1 NO) facilitates control circuit integration and signaling. The 30-01 contact configuration fulfills the requirements for Mirror contacts according to Annex F of IEC/EN 60947-4-1. The VB6A-30-10-84 operates on a 110-127V AC (50/60 Hz) control circuit voltage and is rated for general use at 20 A. Weighing 0.355 kg per unit, this contactor is ideal for applications requiring compact, high-reliability motor control in tight spaces. Typical applications include reversing motor drives, door operators, and conveyor systems where space efficiency and operational safety are paramount. SKU: VB6A-30-10-84.
