The ABB 1SAH100485R9900, also designated MCRA022ARJ, is a compact four-pole mini contactor relay designed for switching control signals and small loads in industrial, commercial and residential applications. Its space-efficient construction makes it particularly suitable for control panels where dependable performance is required within a limited installation area.
This AC-operated contactor relay incorporates two normally open and two normally closed auxiliary contacts. Special screw terminals accommodate ring-tongue cable terminals, helping provide secure electrical connections in machinery, automation and building-control systems.
The MCRA022ARJ operates from a control supply of 110–115 V AC at 50 Hz or 110–120 V AC at 60 Hz. It can switch control signals and small loads up to 6 A at 240 V AC under the AC-15 utilisation category and is suitable for DIN-rail or wall mounting.
Mini contactor relays provide electrically operated switching for control circuits and small loads. Applying the rated control voltage energises the coil and changes the state of the normally open and normally closed contacts, enabling signals to be distributed, interlocked or isolated within an automation system.
The ABB MCRA series combines compact dimensions with flexible mounting and secure ring-tongue connections. Its 2NO + 2NC contact arrangement makes the 1SAH100485R9900 suitable for relay logic, signalling, interlocking and auxiliary control functions in modern electrical installations.
