Schneider LV426843 is a standard MX shunt trip release designed for use with ComPacT NSXm and PowerPact B circuit breakers. This voltage release accessory provides reliable remote opening of the breaker in control applications, with a control circuit rating of 110/130 V AC at 50/60 Hz or 125 V DC. Built with a compact clip-on format, it is easy to integrate into compatible breaker assemblies and features spring terminal connections for straightforward wiring. With an operating threshold of 0.7 Un, impulse or maintained control signal capability, and a response time of under 50 ms, LV426843 is a practical choice for installations requiring efficient electrical tripping functionality.

What does this shunt trip release do?
This accessory is a voltage release used for remote opening of a compatible circuit breaker. When the control voltage is applied, it trips the breaker opening mechanism so the breaker opens electrically rather than by manual operation.
Which breaker ranges is it designed to work with?
It is designed for use with compatible ComPacT NSXm new generation, ComPacT NSXm and PowerPact B breaker platforms. In practical terms, LV426843 is intended as a matching control accessory for those ranges.
What control voltages does it accept?
This unit is rated for 110 to 130 V AC at 50/60 Hz and also for 125 V DC. That makes it suitable for installations using either AC control power in that range or a 125 V DC control circuit.
Is it intended for remote tripping applications?
Yes. It is built for control applications where the breaker needs to be opened from a remote signal, such as from a panel command, interlocking circuit or other electrical control arrangement.
What type of control signal can it work with?
The release is specified for impulse and maintained control signals. The minimum impulse duration stated for operation is 20 ms.
How quickly does it respond when energised?
The specified response time is less than 50 ms, allowing fast breaker opening once the release is triggered.
What is the operating threshold for tripping?
The stated opening threshold is 0.7 Un. In other words, the release is designed to trip at 70% of its rated control voltage during opening conditions.
What type of connection terminal does it use?
It uses a spring terminal connection, which is suited to secure auxiliary wiring within the control circuit.
Is this a standard or special control accessory?
It is described as a standard shunt trip release with device short name MX. This makes it a straightforward choice when a compatible breaker requires a conventional remote opening release.
Can it be used on both AC and DC control systems?
Yes. One of its practical advantages is dual compatibility: 110/130 V AC at 50/60 Hz or 125 V DC, depending on the control system used in the panel.
What kind of application is it generally used in?
This accessory is intended for breaker control functions, especially where electrical opening is needed as part of panel operation, isolation logic or remote command arrangements.
Are there any environmental compliance details available for it?
Yes. The published product information states compliance with EU RoHS requirements and indicates WEEE disposal provisions for the European market. It is also presented as a Green Premium product in the available product data.
- Remote tripping of ComPacT NSXm and PowerPact B circuit breakers from a control panel
- Electrical opening of a breaker when a stop command is sent from push-buttons, switches or control relays
- Integration into building services panels where breakers need to be tripped from a central control point
- Use in industrial distribution boards to disconnect protected circuits without operating the breaker manually
- Connection to emergency stop arrangements that require a breaker to open by electrical signal
- Application in motor control and power distribution systems where fast remote disconnection is required
- Installation in automation cabinets to allow breaker tripping from supervisory control circuits
- Use in energy management and load-shedding schemes where selected circuits must be disconnected automatically
- Incorporation into access-controlled or interlocked systems that must trip a breaker when a defined condition occurs
- Retrofitting compatible Schneider breaker assemblies to add remote opening capability using an MX shunt trip release
