ABB Tmax XT Series Circuit Breaker Accessory, 30V Rated AC Voltage, 110mm Width - 1SDA066389R1 UVR XT1..XT4 24-30VAC/DC

This circuit breaker accessory is designed to integrate with Tmax XT systems as a voltage-operated relay module for control and protection tasks in electrical panels. It accepts low AC or DC control signals and is intended for use alongside modular circuit breakers in industrial automation and electrical distribution environments.

Features and Benefits:

• Accepts 24-30VAC/DC control signals for flexible interfacing
• Operates at up to 30V AC and 30V DC for low-voltage switching
• Conforms to RoHS and IEC standards for regulatory alignment
• Compact footprint measuring 110mm x 60mm for space-efficient installation
• Depth of 140mm enables predictable panel clearance planning

Applications

• Suitable for remote tripping of circuit breakers in control cabinets
• Ideal for integration with automation control cabinets using low-voltage signals
• Used with protective schemes requiring add-on relay functionality
• Can be used for retrofit upgrades to existing Tmax XT-equipped panels

What mounting considerations affect panel layout?

The unit requires a projection of 140mm from the mounting face, so panel depth and adjacent component spacing should be checked before installation.

Which supply types will reliably actuate the device?

Both AC and DC control supplies within the 24-30V range are appropriate for reliable actuation of the internal relay.

What size envelope should be reserved for front-access handling?

Allow a width of 110mm and a height of 60mm to ensure unobstructed access for wiring and servicing.

Are there recognised standards that the product meets?

It is manufactured to comply with RoHS restrictions and relevant IEC requirements for components of this category.
