ABB CA3 Series Auxiliary Contact, 6A Contact Current, 690V Contact Voltage - 1SBN011010T1001 CA3-01


This auxiliary contact provides a Compact front-mounted switching Interface for control and signalling circuits in industrial contactor assemblies. Designed for front-side mounting, it offers a single normally closed contact to monitor or interrupt auxiliary circuits within automation, electrical distribution and control systems.

Features & Benefits


• 6A switching capability at common industrial voltages for dependable load handling
• Rated insulation voltage 690V to support high-voltage auxiliary circuits
• Screw terminals allowing secure conductor connections and simple installation
• Single-pole configuration to minimise panel footprint and simplify wiring
• RoHS compliance ensuring compatibility with restricted-substance requirements

**Applications**


• Suitable for monitoring contactor state in motor control panels
• Ideal for interlock circuits in industrial automation systems
• Used with contactor blocks as a replacement auxiliary contact
• Can be used for signalling circuits on distribution and control panels

What Terminal types are provided for electrical connection?


The unit uses screw-style terminals that accept both ferruled and rigid conductors within the stated cross-sectional ranges.

What conductor sizes can be terminated safely?


Connections accommodate ferruled or insulated ferrules from 0.75mm² up to 2.5mm² and two conductors of 0.75mm² where specified.

How does it perform under frequent switching conditions?


Maximum mechanical switching speed is 3600 cycles per hour, with electrical switching frequencies suited to AC-15 and DC-13 duty categories at specified currents.

What mounting orientation is required for installation?


It is intended for front-side mounting directly onto compatible contactor blocks to register auxiliary operation.
