1SDA066589R1 ABB PLL XT1-XT3 Fixed Open-Position Padlock Device

Why Choose the ABB PLL XT1-XT3 Padlock Device 1SDA066589R1?

The ABB 1SDA066589R1 PLL XT1-XT3 is a fixed padlock device for the open position designed for ABB SACE Tmax XT1 and XT3 moulded case circuit breakers. It provides a mechanical locking provision that allows a compatible circuit breaker to be secured in the open position, helping prevent unintended operation during electrical isolation, servicing and maintenance procedures.

As part of the ABB SACE Tmax XT mechanical accessory range, the PLL device is specifically engineered for the XT1 and XT3 breaker frames. Unlike the removable PLL variant, this model is the fixed open-position padlock provision, providing an integrated locking solution for installations where padlocking capability is required as part of the circuit-breaker operating arrangement.

The 1SDA066589R1 is designed specifically for Tmax XT1 and XT3 circuit breakers and has a product weight of approximately 0.06 kg. Its dedicated open-position locking function makes it suitable for switchboards, control panels and electrical distribution systems where controlled breaker isolation is required.

Reliable Open-Position Locking for Electrical Isolation

Circuit-breaker padlocking accessories provide a mechanical means of preventing operation while downstream equipment is isolated for inspection, maintenance or servicing. By allowing the breaker to be secured in the open position, the ABB PLL helps support controlled electrical isolation procedures and reduces the risk of unintended manual closing.

The ABB PLL 1SDA066589R1 is the fixed open-position locking version for SACE Tmax XT1 and XT3 circuit breakers. Its dedicated design provides a coordinated mechanical interface with compatible Tmax XT breakers, making it suitable for switchboards and distribution equipment where permanent padlock provision is required.

Typical Applications

• Low-voltage electrical distribution switchboards.
• ABB SACE Tmax XT1 and XT3 circuit-breaker installations.
• Electrical maintenance and isolation procedures.
• Industrial control and distribution panels.
• Commercial and infrastructure switchgear assemblies.
• Applications requiring fixed open-position circuit-breaker padlocking.
