ABB 1SBL41 Series Contactor, 125A Contact Current, 48V Coil Voltage - 1SBL419025R8311


This contactor is a DC switching device designed for control applications in industrial electrical systems. It operates with a 48V control circuit and is intended to manage three-pole power paths, providing reliable switching of medium-voltage DC loads up to 690 V. The unit includes a mix of main and auxiliary contacts and is suited to panel- or cabinet-mounted installations where screw terminals are required.

Features and Benefits:


• 125 A continuous contact rating for heavy-duty current handling
• 3-pole configuration enabling simultaneous multi-phase DC switching
• 1 NO and 1 NC auxiliary contact for Basic control logic integration
• 48V Coil voltage for compatibility with common control supplies
• IEC 60947-4-1 compliant construction for recognised electrical behaviour
• Rated for operation between −40 °C and 70 °C for varied environments

Applications


• Suitable for battery bank isolation in DC storage systems
• Ideal for motor-drive disconnect in industrial automation panels
• Used for load switching in renewable energy converters
• Can be used for control and protection circuits in traction systems

What type of Terminal connections does it use for wiring?


Termination is via screw terminals, allowing secure clamping of conductor lugs and straightforward installation with standard tools.

How many auxiliary contacts are available for control circuits?


Two auxiliary contacts are provided, arranged as one normally open and one normally closed contact for straightforward signalling and interlocking.

What approvals indicate suitability for safety-conscious installations?


The device meets IEC standards and holds approvals from UL/CSA and VDE, reflecting adherence to recognised industrial specifications.

What is the operational current for the Coil control circuit?


The control circuitry is rated for an operational current of 6 A, matching typical control-loop requirements.
