Why Choose the ABB AFS460-30-12-70 Safety Contactor?
The ABB 1SFL597081R7012, designated AFS460-30-12-70, is a robust three-pole safety contactor designed for motor control and high-power switching within safety-related industrial machinery. Its design supports integration into machine systems developed in accordance with EN ISO 13849 and EN 62061.
The contactor controls three-phase motors rated up to 250 kW at 400 V AC in AC-3 duty and switches power circuits up to 700 A in AC-1 duty. ABB AF technology provides a wide 100–250 V AC/DC control range, distinct operation during supply variations and integrated surge suppression.
Three normally open main contacts are complemented by one normally open and two normally closed auxiliary contacts. A readily identifiable yellow, low-energy auxiliary contact block provides the status-feedback contacts required for machine-safety circuits, while bar-type main terminals support high-current connections.

Reliable Switching for Machine-Safety Systems
Safety contactors provide controlled power switching together with auxiliary status feedback for monitoring within safety-related control systems. The ABB AFS460-30-12-70 combines three high-current main poles with mechanically linked auxiliary contacts suited to machinery safety applications.
The yellow low-energy auxiliary contact block helps engineers identify the contacts intended for feedback circuits. Its electronic AF coil accommodates a broad AC/DC control-voltage range, while integrated surge suppression simplifies panel construction and protects connected control equipment from coil-switching transients.
Typical Applications
- Safety-related industrial motor-control systems.
- Emergency-stop power-disconnection circuits.
- Production and assembly machinery.
- Conveyors and material handling equipment.
- Robotic manufacturing cells.
- High-power machine control panels requiring monitored contactor feedback.
