What type of electrical accessory is this component?
It is a shunt opening release, also commonly described as a shunt trip. It enables a compatible circuit breaker to be opened by applying an external control voltage.
Which circuit breaker frame sizes is this shunt opening release designed for?
This accessory is designed for ABB SACE Tmax XT5 and XT6 circuit breaker frame sizes. Compatibility should be confirmed against the exact breaker configuration before installation.
What control voltage range does this accessory accept?
The accessory is rated for a control supply of 110–240 V AC or 110–250 V DC.
What does permanent service mean for a shunt opening release?
Permanent service indicates that the release is designed for applications where the control supply may remain applied continuously, rather than being limited to a brief operating pulse.
What happens when the rated control voltage is applied?
Applying the correct control voltage energises the release mechanism, causing the compatible circuit breaker to open.
Can this accessory close a circuit breaker remotely?
No. A shunt opening release is intended to initiate breaker opening only. Closing or resetting the breaker requires the appropriate separate mechanism and circuit arrangement.
Can it be powered by either an AC or a DC control circuit?
Yes. The specified operating range covers both AC and DC control supplies, provided the applied voltage remains within the relevant rated range.
Is this component a complete circuit breaker?
No. It is an internal electrical accessory intended for use with a compatible ABB SACE Tmax XT5 or XT6 circuit breaker.
What are typical applications for this accessory?
Typical applications include remote breaker opening, emergency-stop circuits, process interlocking, building management controls and automated electrical isolation arrangements.
What should be checked before fitting the accessory?
Confirm the breaker frame size, accessory mounting position, control voltage, AC or DC supply type, wiring arrangement and compatibility with any other installed breaker accessories.
Does polarity matter when using a DC control supply?
The wiring and terminal markings supplied for the breaker accessory should be followed. Where polarity is indicated, the positive and negative connections must be observed.
Can the accessory be used outside its stated voltage range?
No. Applying a voltage outside the stated AC or DC range may prevent reliable operation or damage the release.
Which standards are associated with this accessory?
The available product specifications identify IEC and UL as the applicable standards or certification frameworks.
What is the product classification for customs purposes?
The listed commodity code is 853890, covering parts intended for use with specified electrical switching or protection apparatus.
Is professional installation recommended?
Yes. Installation and electrical testing should be completed by a suitably qualified person in accordance with the breaker documentation and applicable electrical regulations.
