1SDA054882R1 ABB UVR T4-T5-T6 60 V AC/DC Undervoltage Release

Why Choose the ABB 1SDA054882R1 UVR T4-T5-T6 60 V AC/DC Undervoltage Release?

The ABB 1SDA054882R1 is a 60 V AC/DC undervoltage release (UVR) designed for compatible ABB SACE Tmax T4, T5 and T6 moulded-case circuit breakers. It provides an electrical release function that responds when the associated control-supply voltage falls below the required operating level.

ABB identifies this accessory as UVR T4-T5-T6 60 VAC/DC. It is rated for both 60 V AC and 60 V DC control supplies, providing a manufacturer-matched solution for compatible Tmax circuit breakers used in industrial and commercial low-voltage distribution systems.

An undervoltage release is used where circuit-breaker operation needs to depend on the availability of an adequate control voltage. The 1SDA054882R1 integrates with compatible Tmax T4, T5 and T6 operating mechanisms, supporting control schemes that require the breaker to respond appropriately to loss or reduction of its monitored supply.

Reliable Undervoltage-Dependent Circuit-Breaker Control

An undervoltage release allows the operating state of a compatible circuit breaker to depend on the presence of a suitable control voltage. If the supply falls sufficiently, the release acts on the circuit-breaker mechanism, supporting installations where equipment must respond to loss or reduction of the monitored control supply.

The ABB 1SDA054882R1 is designed for 60 V AC/DC control circuits and is compatible with suitable Tmax T4, T5 and T6 circuit breakers. Its AC and DC compatibility makes it suitable for a range of industrial control architectures that employ a nominal 60 V control supply.

Typical Applications

• Undervoltage-dependent control of compatible ABB Tmax circuit breakers.
• Industrial low-voltage switchboards and distribution panels.
• 60 V AC or DC electrical control systems.
• Manufacturing and process power distribution equipment.
• Commercial and industrial switchgear assemblies.
• Control schemes requiring circuit-breaker response to loss or reduction of control voltage.
