Article No. 147187

Product Overview

The R. STAHL 8146/5-V27-101-065-00-11-1 motor protection circuit breakers are designed for the protection of Ex e and Ex d motors, as well as associated conductors and systems. These devices feature a robust housing made of glass-fiber reinforced polyester resin. Optional accessories include a undervoltage release, a working current release, and an ammeter with auxiliary contact.

The standard versions are equipped with an adjustable, phase-sensitive thermal overcurrent release, or an instantaneous electromagnetic release, which must be specified at the time of order. Retrofitting is not possible.
