Remote Control MT400/630 220-240V 50/60HZ 208-277V 60HZ

The Schneider Electric LV432641 MT400/630 remote control is a motorized mechanism designed to automate the opening and closing operations of ComPacT NSX400 and NSX630 circuit breakers. It operates with a control voltage of 220-240 V AC at 50/60 Hz or 208-277 V AC at 60 Hz and automatically charges the mechanism springs, allowing the breaker to be controlled electrically and remotely.

This accessory is especially suitable for electrical panels that require remote operation, automation, controlled reclosure, or integration of the circuit breaker into management and control systems. It supports electrical commands both by pulse and maintained, offers fast operating times, and keeps visual access to the breaker settings and indications once installed.

MT400/630 remote control for ComPacT NSX400 and NSX630

Reference LV432641 belongs to Schneider Electric's MT400/630 family of motorized mechanisms. It is designed for ComPacT NSX400 and ComPacT NSX630 circuit breaker frames, including compatible configurations from the NSX family for direct current.

The mechanism makes it possible to convert a manually operated circuit breaker into equipment ready to receive electrical opening and closing commands. In this way, it can be integrated into distribution panels where operation must be carried out from a remote system, automation, or control station.

Automatic spring charging

The main function of the MT400/630 is to perform the automatic charging of the circuit breaker mechanism springs. Once installed, the remote control automatically prepares the mechanism for subsequent operations, eliminating the need to perform this task manually.

This feature facilitates remote opening and closing sequences and is especially useful in automated installations or electrical panels where the breaker must be operated without direct intervention on the front panel.

Control power supply at 220-240 V AC

The Schneider Electric LV432641 is designed to operate with the following control voltages:

• 220-240 V AC at 50/60 Hz.
• 208-277 V AC at 60 Hz.

The control voltage should be checked before selecting the accessory, as Schneider Electric offers equivalent MT400/630 mechanisms with other control voltages.

Pulse or maintained commands

The remote control supports two types of control signals:

• Pulse command.
• Maintained command.

This flexibility makes it suitable for different automation and control schemes, adapting to systems that use momentary pulses or maintained signals to command the opening and closing of the breaker.

Fast opening and closing

Schneider Electric specifies reduced response times for electrical operations:

• Opening time: less than 600 ms.
• Closing time: less than 80 ms.
• Maximum operating frequency: 4 operations per minute.

These performance characteristics make the mechanism suitable for automation systems where fast and controlled circuit breaker response is required.

Maximum consumption of 500 VA during operation

The electrical consumption of the mechanism is mainly concentrated during operating actions. Schneider Electric specifies:

• Maximum consumption during closing: 500 VA.
• Maximum consumption during opening: 500 VA.

These values should be taken into account to correctly size the control circuit and its power supply.

Manual and automatic operating selector

The motorized mechanisms in the ComPacT NSX family include selection between manual and automatic operation. In automatic mode, the mechanism accepts electrical operating commands. In manual mode, electrical commands are inhibited and the breaker can be operated directly using its front handle.

This feature simplifies maintenance and commissioning operations, as it allows switching from remote control to local operation when needed.

Breaker locking in OFF position

The remote control maintains the possibility of locking the breaker in the open position. Schneider Electric specifies a system compatible with:

• Locking in OFF position.
• 1 to 3 padlocks.
• Padlock diameter: 5 to 8 mm.

The lock helps prevent unauthorized operation during maintenance work or intervention on the installation.

Maintains breaker settings visible

Once the motorized mechanism is installed, the main indications of the circuit breaker remain visible and accessible. This includes the settings and signaling of the compatible trip unit.

Schneider Electric also indicates that the breaker’s suitability for isolation is maintained and that the front panel provides double insulation within the configuration defined by the manufacturer.

SDE adapter included

The MT400/630 motorized mechanism is supplied with an SDE adapter. This component facilitates the integration of trip indication associated with electrical fault tripping within compatible ComPacT NSX configurations.

The use of auxiliary contacts and additional accessories must be carried out according to the breaker configuration and the control scheme defined for the installation.

Applications of the LV432641 remote control

The motorized mechanism is especially useful in installations where circuit breakers must be integrated into control systems or operated without direct access to the panel.

• Low-voltage main switchboards.
• Industrial distribution panels.
• Transfer and automation systems.
• Installations with remote breaker control.
• Energy management systems.
• Installations with automated reclosure procedures.
• Infrastructure and commercial buildings.
• Production centers and industrial processes.
