Why Choose the ABB 1SDA068451R1 Tmax XT4L 160 MCCB?
The ABB 1SDA068451R1 is a compact and reliable Tmax XT4L moulded case circuit breaker (MCCB) designed for low voltage motor protection and electrical distribution applications. Part of the trusted ABB SACE Tmax XT range, this breaker is engineered for dependable short circuit protection in industrial control panels, machinery systems and switchgear assemblies.
This model features a fixed three-pole configuration with front terminals and an MA magnetic-only release. The magnetic trip setting is adjustable, allowing the breaker to be matched to motor starting conditions and short circuit protection requirements without thermal overload protection built into the breaker.
With a rated current of 10 A, 690 V AC rated operational voltage and 120 kA breaking capacity at 415 V AC, the XT4L 160 is suitable for demanding installations where reliable fault interruption and robust ABB engineering are required.

Reliable Magnetic Protection for Motor Circuits
Magnetic-only MCCBs such as the ABB Tmax XT4L MA range are commonly used for short circuit protection in motor circuits where separate overload protection is provided by a motor starter, overload relay or drive system. This arrangement allows the breaker to respond rapidly to high fault currents while avoiding unnecessary tripping during normal motor starting.
The XT4L series combines compact dimensions, high breaking capacity and ABB’s proven circuit protection technology, making it a strong choice for panel builders, machine builders and electrical contractors working on industrial control and power distribution systems.
Typical Applications
- Motor protection circuits.
- Industrial control panels.
- Motor control centres.
- Low voltage switchboards.
- OEM machinery and automation systems.
- Commercial and industrial distribution systems.
