ABB CAL4-11 Auxiliary Contact Block

The CAL4-11 is a 2-pole, side-mounted auxiliary contact block with screw terminals, providing one instantaneous normally open (N.O.) and one normally closed (N.C.) contact. It clips directly onto the right- or left-hand side of a wide range of ABB AF and NF series contactors and contactor relays, making it a flexible accessory for panel builders and industrial maintenance teams working across UAE motor control installations.

Key Features

  • 1 N.O. + 1 N.C. instantaneous auxiliary contacts for signalling and control interlocking
  • Side-mounted, clip-on design fitting the right- and/or left-hand side of compatible AF and NF series contactors
  • Compatible with an extensive range of ABB AF09 to AF96 contactors and NF22E to NF80E contactor relays
  • Rated insulation voltage of 690V and impulse withstand voltage of 6kV for reliable performance in standard industrial environments
  • Genuine ABB quality

Applications

  • Control circuit expansion on industrial contactor assemblies in UAE facilities
  • Retrofit accessory for existing ABB AF and NF series contactor installations

FAQ

  • What does this contactor control?
    It's an electrically-operated switch used to make/break a load circuit repeatedly under remote or automatic control — commonly lighting banks, motors, HVAC equipment, or heating loads switched via a timer, BMS, or control relay.
  • Does this need a separate overload relay for motor protection?
    Yes, if it's controlling a motor — a contactor alone doesn't protect against sustained overload. Pair it with a compatible thermal overload relay (see ABB's matching TF/TA-series relays) to form a full motor starter.
  • Can I control this contactor with a timer or BMS?
    Yes — the coil is designed for remote switching from a timer, PLC, BMS, or control relay rather than direct manual operation, making it suited to automated load switching.
  • Can I install this myself?
    No. Contactors are wired into live control and power circuits and must be installed by a licensed electrician in accordance with UAE wiring regulations.
