What is the ABB CA4-04E auxiliary contact block used for?
The ABB CA4-04E is a 4-pole front-mounted auxiliary contact block designed for use with AF series contactors (AF09–AF96). It provides 4 normally closed (N.C.) instantaneous contacts for auxiliary circuit signaling or interlocking in control panels.
What are the electrical ratings of the CA4-04E auxiliary contact block?
The CA4-04E is rated for up to 690 V AC and 16 A thermal current at 40 °C. Under AC-15 duty, it handles 6 A at 24/127 V, 4 A at 220/240 V, 3 A at 400/440 V, and 2 A at 500/690 V. For DC-13 duty, current ranges from 6 A at 24 V to 0.1 A at 600 V.
Which standards and certifications does the ABB CA4-04E comply with?
This model complies with IEC/EN 60947-5-1, UL 60947-5-1, and CSA C22.2 No. 60947-5-1-14, ensuring international conformity for control circuit components.
What are the mechanical and short-time withstand capabilities of the CA4-04E?
The auxiliary block withstands short-time currents up to 140 A for 0.1 s and 100 A for 1 s. Its maximum mechanical switching frequency is 3600 cycles/hour, ensuring long operational life under typical industrial use.
What type of terminals and wiring capacity does the CA4-04E support?
It features screw terminals with IP20 protection. The wiring capacity includes 0.75–2.5 mm² for both flexible and rigid conductors, with a recommended stripping length of 10 mm. It also supports ferruled terminations for vibration-resistant connections.
Which ABB contactors are compatible with the CA4-04E?
It is suitable for AF09–AF96 and AFC09–AFC96 series contactors, including variants like AF09Z, AF26B, AF52, and AF80. Refer to ABB’s compatibility list or contact Shansen for confirmation.
What is the rated impulse and insulation voltage for the CA4-04E?
The block has a rated insulation voltage (Ui) of 690 V AC (IEC) and 600 V (UL/CSA), with a rated impulse withstand voltage (Uimp) of 6 kV, suitable for standard industrial environments.
