2007年8月16日 · Like Aleham said, "shunt trip" is the term used in low voltage, e.g. molded case, circuit breakers where it is commonly an add-on component. The CB has thermal/magnetic trip capabilities, but it also has the ability to trip electronically say from a Feeder Protection Relay say like the GE SR750.

2024年12月4日 · Hello. what is the purpose of shunt trip breakers in a commercial kitchen hood control panel? I have built over 30 controld panels for kitchen hoods . Never have useda shunt trip trip breaker ever . The contol panels are controlled by the ansul micro switch. Operation is cookline outlets energized non dependent if control box is on or off.

2019年6月22日 · Without power to these remote devices, the shunt trip devices would fail to operate. Always verify that power is turned off before working on the electrical equipment and make sure the power has been locked off. It must be shown the shunt trip is listed as a “service disconnecting device” as required by 230.66. I would be surprised if it is.

2020年11月6日 · not to shunt trip the breakers feeding the elevator. The shunt trip process is controlled by the Smoke and Heat detectors installed in the elevator shaft itself tied to the shunt trip breakers, not from the auxiliary contacts in the elevator service disconnect. Someone more knowledgeable about such will probably chime in. JAP>

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 ...

2007年11月9日 · If you are suppose to shunt trip any 125v devices underneath an exhaust hood, and all 125v, 15-20amp devices in the same kitchen shall be protected by ground fault devices (breakers or receptacles), Then what do you do when you have a device that falls under both of thos rules and requires shunt tripping because of being underneath the hood ...

2017年6月6日 · Siemens make a 2-pole gfci shunt trip; Google is your friend. If you have a lot of electrical for a renovation or new install, put the required circuits in a sub panel and feed it with a shunt trip breaker. Your branch circuits can be GFCI. If you have only one or …

2007年5月7日 · The flux transfer shunt trip takes very little energy to release it and the capacive trip devide is a capacitor which stores power for a brief period of time. If control power is lost the capacitive trip device store enough energy that can be used and discharged into the flux transfer shunt trip with is somple contact closure.

2006年11月10日 · That requirement can be met with shunt trip breakers and electric shut off valves on the gas lines. In doing medium to large kitchens I would put in shunt and non-shunt panels and then just shunt trip the main of the shunt panels rather than having a bunch of branch breakers with shunts.

2011年7月30日 · I have never seen a shunt trip breaker that could be resettable via control wiring. They are always in my experience manual reset only. Also some shunt capable breakers will have multiple configurations for their accessories so I suppose it is possible that the accessory is installed in the wrong slot or the wrong orientation to the trip lever ...
