1SAL103099R9901 ABB MC1AB00AT7 Mini Contactor Compact Control Contactor

Why Choose the ABB 1SAL103099R9901 MC1AB00AT7 Mini Contactor?

The ABB 1SAL103099R9901 (MC1AB00AT7) is a compact and reliable four-pole mini contactor designed for switching single-phase and three-phase loads in industrial, commercial and building automation applications. As part of the ABB MC1A mini contactor series, it combines high switching performance with a space-saving design for control panels and machinery where installation space is limited.

The MC1AB00AT7 features 2 normally open (NO) and 2 normally closed (NC) main contacts, providing a versatile four-pole configuration for load switching and control applications. Its AC-operated electromagnetic coil and screw terminal connections provide straightforward integration into conventional industrial control systems, while additional auxiliary contacts can be fitted where extra signalling or interlocking functions are required.

With a 240 V AC 50/60 Hz control coil, a rated operational current of 9 A in AC-3 duty at 400 V and a motor switching capacity of 4 kW at 400 V, the MC1AB00AT7 delivers dependable performance from a compact enclosure. For AC-1 applications it can switch loads up to 20 A at 690 V, making it suitable for a broad range of industrial and building control duties.

Compact and Reliable Switching for Control Systems

Mini contactors such as the ABB MC1AB00AT7 use an electromagnetic coil to operate their main contacts, allowing electrical loads to be switched from a separate control circuit. Their compact dimensions make them particularly useful in industrial machinery, commercial equipment and building automation panels where conventional contactors would occupy unnecessary installation space.

The MC1AB00AT7 combines two normally open and two normally closed main contacts with a 240 V AC coil and industrial switching ratings of up to 9 A in AC-3 duty and 20 A in AC-1 duty. Its compact construction, flexible mounting options and compatibility with additional auxiliary contacts make it a versatile component for machine builders, panel builders and automation engineers.

Typical Applications

• Industrial control and automation panels.
• Single-phase and three-phase load switching.
• Small motor control and starter assemblies.
• Heating, ventilation and HVAC equipment.
• Building automation and commercial electrical systems.
• OEM machinery and compact production equipment.
