ABB 1SBN010140R1004

The CA4-04E auxiliary contact block is engineered for front mounting and is compatible with various contactor models, specifically designed to match the terminal arrangement of 3-pole AF26(Z)(B)..96-30-00, AF40..96-30-11, AFC26..38-30-00, and 4-pole AF(C)09..16(Z)(B)-40-00, AF40..80-40-00 contactors. It is equipped with four normally closed (N.C.) instantaneous contacts, making it suitable for standard industrial applications.

With compact dimensions of 43 mm in width, 39.5 mm in depth, and 43 mm in height, the CA4-04E weighs 0.055 kg. The block supports flexible and rigid wire connections, capable of handling a range of conductor sizes from 0.75 mm² to 2.5 mm². The auxiliary circuit can operate at a rated insulation voltage of 690 V, while providing a mechanical switching frequency of 3600 cycles per hour and an electrical switching frequency of up to 1200 cycles per hour for AC-15 and 900 cycles per hour for DC-13 applications.

Compliance with IEC 60947-5-1 standards ensures reliability and safety, with a rated short-time withstand current of 140 A for 0.1 seconds and 100 A for 1 second, confirming its capability in demanding environments. The CA4-04E also features an impulse withstand voltage rating of 6 kV, enhancing its durability in various industrial settings. Additionally, the degree of protection for the auxiliary terminals is rated at IP20, safeguarding against potential environmental hazards.
