3-Phase Connection Busbar · 45 mm Pitch 63 For 3 Breakers · Lovato 11SMX9033
Three-phase connection busbar for Lovato SM1P and SM1R motor protection circuit breakers, with 45 mm (1.77 in) spacing, 63 A maximum current, and 690 V insulation rating. Commonly used to link three breakers in a compact motor control assembly or panelboard section.
What this product is for
The Lovato 11SMX9033 is a three-phase connection busbar used to interconnect three compatible motor protection circuit breakers in the SM1 series. It helps create a cleaner and more consistent power distribution layout inside motor control panels and industrial assemblies.
Use for
Use for SM1P and SM1R motor protection circuit breakers where 45 mm (1.77 in) device spacing is required. Suitable for panel builders, OEMs, and maintenance electricians assembling compact three-phase motor starter or feeder sections.
Avoid for
Avoid using this busbar with non-compatible breaker families, different pole spacing, or applications that exceed the published current or voltage limits. It is an accessory for specific Lovato devices, not a universal busbar.
Best for
Best for control panels and power distribution assemblies where you need a factory-matched busbar for three breakers, reduced wiring time, and a neater internal layout.
Installed in
Typically installed in industrial control panels, motor control centres, machinery panels, and commercial electrical enclosures where multiple motor protection breakers are grouped together.
Why this product exists
This accessory provides a direct three-phase link between compatible breakers, helping reduce point-to-point wiring and maintain consistent phase distribution. In practice, this can simplify assembly and service work compared with individual jumper conductors.
Compared with similar products
Compared with field-made jumper wiring, a matched busbar can provide a more compact and repeatable installation. Compared with longer busbars for larger breaker groups, this model is specifically sized for 3 breakers and 45 mm spacing. Always confirm accessory compatibility with the exact breaker series before ordering.
