Allen Bradley Shunt Trip, 250V DC Maximum Voltage Rating, Right Mounting - 189-AST1

Choose this shunt trip from Rockwell Automation’s Allen Bradley range to add an extra layer of protection to your circuit breaker setup. You can use it to supplement an existing breaker, as it mounts onto its right side and manually trips the main unit whenever its shunt trip terminals are energised. This protects you, and any connected equipment, from the risks of overcurrent issues like short-circuits, ground faults and thermal overloads. As this trip has a switch, you also have the option of using it as a manual reset button.

• Simple clip-on mounting style makes it easy to install
• Operating temperature range of -25°C to +55°C, so it suits harsh environments
• Resists surges up to 4kV without equipment failure for reliability and user safety
