SX9033 range overview
One range for starting, stopping and braking
The SX9033 range is positioned for industrial motor control duties where machinery needs dependable starting, stopping and motor protection. The available information covers DOL starters, IP65 soft-start brake modules, 5-head brake modules and supporting fuse accessories.
Range families
- DOL starters for 230V and 400V motor applications.
- Soft-start brake modules with matched overload options.
- Multi-head brake modules for larger machine installations.
- Fuses and carriers for complete SX range support.
Standstill monitoring
Brake module details include standstill monitoring with null adjustment and internal contactor switching for the DC brake output.
Restart interlock
The X5 and X6 interlock contact is used to help avoid motor restart while braking current is being injected.
Brake safety timer
A built-in override timer stops the braking cycle if standstill is not detected within the safety time.
Why SX9033
Benefits for machine builders and maintenance teams
Specified around real machinery
Coverage spans 2kW single-phase starters through to 15kW 400V brake modules, giving engineers practical options across common motor sizes.
Range-led procurement
Starters, brake modules, overload ranges, fuses and carriers can be discussed together instead of treating each item as an isolated part.
