ABB 1SDA067576R1 XT2S 160 TMA 50-500 4p F F moulded case circuit breaker, a 50 A four-pole fixed MCCB with front terminals and TMA thermomagnetic release for low voltage circuit protection.
£629.76
The ABB 1SDA067576R1 is a reliable SACE Tmax XT moulded case circuit breaker designed to provide dependable protection for low voltage electrical distribution systems. Part of the ABB Tmax XT2 series, this MCCB is suitable for industrial, commercial and panel building applications where compact four-pole circuit protection is required.
This breaker is supplied in a fixed four-pole configuration with front terminals, making it suitable for installation in switchboards, control cabinets and distribution assemblies. Its integrated TMA thermomagnetic release provides adjustable overload and short-circuit protection, helping protect cables, equipment and downstream electrical circuits.
With a rated current of 50 A and an adjustable magnetic trip setting range of 250-500 A, the ABB 1SDA067576R1 is ideal for four-pole low voltage distribution applications where neutral switching or isolation is required. The XT2S 160 frame combines compact dimensions with strong breaking performance for demanding electrical installations.
Moulded case circuit breakers such as the ABB 1SDA067576R1 are used to protect electrical installations from overloads and short circuits. By safely interrupting fault currents, they help reduce equipment damage, improve operational safety and support reliable power distribution.
The four-pole design is particularly useful where the neutral conductor must also be switched or isolated. This makes the XT2S 160 4-pole MCCB suitable for distribution boards, industrial control panels, generator systems and commercial installations requiring dependable circuit protection.
