ABB Tmax XT Circuit Breaker Accessory Rated 380-440VAC 110mm Width 140mm Depth 60mm 1SDA066333R1 SOR-C XT2-XT4 W 380-440VAC

ABB 1SDA066333R1 SOR-C XT2-XT4 Circuit Breaker Accessory is an essential component for the Tmax XT range of circuit breakers, facilitating controlled breaker opening via electrical signals. Designed for industrial and commercial electrical applications, this accessory supports safe and efficient circuit interruption mechanisms.

The cable shunt opening release (SOR) ensures the circuit breaker opens reliably when an electrical control is applied and operates between 70% and 110% of the rated supply voltage, accommodating both alternating current and direct current systems.

The accessory features a built-in limit contact that automatically disconnects power supply in the breaker’s open position when the trip unit is activated, enhancing operational safety and system protection.

This device has compact net dimensions of 140 mm depth, 110 mm width, and 60 mm height, making it suitable for installation in tight or constrained electrical panels and switchgear assemblies within industrial, manufacturing, and commercial electrical infrastructure settings.

Rated for operation at 380 to 440 Vac, the SOR accessory is compatible specifically with withdrawable Tmax XT2 and XT4 circuit breakers, offering modularity and ease of replacement or upgrade.

Manufactured under the stringent IEC 60947-2 standard and compliant with RoHS directives, this accessory guarantees performance reliability along with environmental compliance.

Originating from Italy, this ABB product aligns with global quality and safety expectations, ideal for electrical panel builders, maintenance engineers, and industrial automation professionals.

The shunt opening release allows non-permanent electrical breaker operation. Voltage operational range ensures adaptable applications. Built-in limit contact enhances safety by power shut-off on trip. Compact form factor for flexible panel integration.
