ABB 1SBL41 Series Contactor, 75A Contact Current, 690V Contact Voltage - 1SBL417001R7211


This contactor is a three-pole switching device designed to control three-phase motors and heavy power circuits in industrial environments. It operates from a low-voltage DC control range and is intended for use where robust switching of high-voltage, high-current loads is required. The unit integrates auxiliary contacts and screw terminals for straightforward wiring in control panels and field installations.

Features and Benefits:


• 72A operational current supports continuous motor loads
• 75A contact rating for reliable switching capacity
• 690V contact voltage enables high-voltage circuit use
• 37kW power rating for substantial motor drive capability
• 20–60V DC Coil range offers flexible control voltages
• 1NO1NC auxiliary contacts permit straightforward interlocking

Applications


• Suitable for controlling 3-phase motor starters in factories
• Ideal for power distribution circuits in industrial plants
• Used with DC control systems in automation panels
• Can be used for retrofit railway traction equipment installations
• Suitable for use in rolling stock where shock and vibration standards apply

What Terminal arrangement does it use for field wiring?


Termination is via screw‑type connections for both power and auxiliary circuits, providing secure clamping for copper conductors.

What environmental temperatures can it tolerate during operation?


The device is specified to operate between -25°C and 55°C, covering typical indoor and some outdoor plant conditions.

How many poles are used for main power switching and what is their configuration?


Main power switching is carried out across three poles in a 3P configuration to manage three‑phase supplies.

What auxiliary contact arrangement is available for control logic integration?


It provides two auxiliary contacts arranged as one normally open and one normally closed to assist interlock and signalling functions.

Which standards apply to its use in rail and industrial contexts?


Relevant standards include approvals for electrical switching and selected railway and industrial applicable parts to address shock, vibration and safety requirements.
