Article No.: 249188

Product Overview

The R. STAHL 8146/5-V27 series motor starters are circuit breakers designed for motor protection in Ex e and Ex d environments. They offer protection for motors, associated lines, and installations. Standard variants are equipped with an adjustable, phase-sensitive thermal overcurrent release or an electromagnetic instantaneous release, which must be specified at the time of order. Retrofitting is not possible.

Line and system protection for Ex e and Ex d motors
Robust housing made of glass-fiber reinforced polyester resin
Optional: undervoltage release, working current release, ammeter, auxiliary contact
