Why Choose the ABB 1SAL103000R9901 MC1CA00ATWJ Mini Contactor?
The ABB 1SAL103000R9901 (MC1CA00ATWJ) is a compact and reliable four-pole mini contactor designed for switching electrical loads and control signals in industrial, commercial and building automation applications. As part of the ABB MC1C mini contactor range, it combines high switching capability with a space-saving format for installations where panel space is limited.
The MC1CA00ATWJ features 4 normally closed (NC) main contacts and an extended operating range DC coil. Its four-pole configuration makes it suitable for switching and control applications requiring multiple normally closed power contacts, while screw terminals provide secure and straightforward electrical connections.
With a 110 V DC control coil, a rated operational current of 9 A in AC-3 duty at 400 V and an AC-3 motor switching capacity of 4 kW at 400 V, the MC1CA00ATWJ delivers strong performance from a compact enclosure. For AC-1 loads it provides a rated operational current of up to 20 A, with a main-circuit rated operational voltage of up to 690 V AC.

Compact and Reliable Switching for Control Systems
Mini contactors such as the ABB MC1CA00ATWJ provide electromagnetic switching of electrical loads from a separate control circuit. Their compact dimensions make them particularly useful in machinery, building controls and industrial panels where conventional contactors would consume unnecessary installation space.
The MC1CA00ATWJ combines four normally closed main contacts with a 110 V DC extended-range coil and industrial switching ratings of up to 9 A in AC-3 duty and 20 A in AC-1 duty. Front-mounted and side-mounted auxiliary contacts can also be added where additional signalling, interlocking or control contacts are required.
Typical Applications
- Industrial control and automation panels.
- Electrical load switching systems.
- Machine control and interlocking circuits.
- Building automation and HVAC equipment.
- Control signal switching applications.
- OEM machinery and compact electrical assemblies.
