Never have useda shunt trip trip breaker ever . The contol panels are controlled by the ansul micro switch. Operation is cookline outlets...

2010年12月12日 · Add a 120v dedicated ckt for shunt trip control wiring. The shunt doesn't draw much so a 15 amp will do. The fire alarm contractor should supply a set of normally open contacts controlled by the fire alarm panel. Send 2 conductors from here to the shunt trip device. You have now put a single pole switch in line with the load ie the shut trip ...

2009年8月21日 · I have a question about shunt trip breakers. In post #3, the first breaker pictured says, "Internal contacts open coil circuit when circuit breaker or interrupter is in any open position". Is this true of all or even most shunt trip breakers? In the directions for installing a trip coil in an I-line breaker, I did not see any labels like the ...

2021年8月6日 · A Shunt Trip (ST) is simply an additional electro-magnet coil that you can control from the outside that acts on that same trip bar inside of the breaker. So is an Under Voltage Release (UVR) mechanism, except it is ALWAYS energized and DE …

2012年8月27日 · A shunt trip is an accessory, not a type of breaker. It would be like saying "I have an air conditioned car" So the breaker type won't tell you the coil voltage, it will be on a nameplate if it came from the factory with the shunt trip coil or if added aftermarket you may have to look on the coil itself.

2005年9月26日 · A "shunt breaker" receives an external signal that activates a trip mechanism internal to the breaker. This has nothing to do with the amount of current any single device would draw. You use a "shunt breaker" to force one load to turn off, whereas you may wish other loads to continue to run.

2007年3月12日 · Common accessories include a simple shunt trip that has (2) wires. By applying a specific voltage to those wires causes the shunt trip to hit the trip bar of the breaker, tripping the breaker. When that occurs a cut-off switch located usually on the shunt trip immediately opens the shunt trip circuit removing power from the shunt trip coil.

2008年4月18日 · 3) if there are "HEAT PRODUCING" electical items under the hood I disconnect those with a shunt trip breaker activated via the ANSUL system. Like an electric fryer, electric grill, etc. 4) I do NOT disconnect general purpose receptacles that supply refrigeration power, timer power, or other non-heat generating electrical items that are under ...
