ABB CA4 Series Auxiliary Contact, 6A Operational Current, 690V Rated Insulation Voltage - 1SBN010140R1340 CA4-40U


This auxiliary contact provides four normally open instantaneous contacts for front mounting on contactors, supplying signalling and interlock functions in control circuits. It is designed for standard industrial environments and attaches to the front side of compatible contactor frames, offering screw-terminal connections for straightforward wiring.

Features & Benefits


• 6A contact current for low-power control circuits
• Rated for 600V DC and 690V AC to handle varied supplies
• Mechanical durability 10M cycles for extended service life
• Operates between -40°C and 70°C for a wide temperature range
• Front-mount format for simple integration on contactor face
• Screw terminals enable secure conductor connections

**Applications**


• Suitable for motor starter status signalling in automation panels
• Ideal for interlock functions on industrial contactors
• Used with AF09–AF16 contactors requiring auxiliary contacts
• Can be used for control-circuit indications in switchgear
• Used for safety-circuit feedback in manufacturing equipment

What Terminal arrangements accept standard wiring ferrules?


The terminals accept flexible and rigid conductors

compatible ranges include 0.75–2.5 mm² for single conductors and up to 1.5 mm² for dual insulated ferrules, accommodating common ferrule sizes used in control panels.

How does the unit perform under short-duration fault conditions?


It withstands short-time currents with rated short-time withstand values specified for brief fault intervals, supporting 140 A for 0.1 s and 100 A for 1 s in AC-15 switching duty.

What insulation and impulse withstand ratings apply to the contacts?


The device has a rated insulation voltage of 690V and an impulse withstand capability of 6 kV, suitable for typical industrial control-system overvoltage conditions.

Which mounting and compatibility considerations should be observed?


It is intended for front-side mounting and matches Terminal arrangements of certain 3-pole contactor frames, ensuring correct alignment and mechanical fit when paired with the specified contactor types.
