ABB CA4/CAL4 Side Mount Auxiliary Contact Block, 1NO-1NC

The ABB CA4/CAL4 side mount auxiliary contact block is used for the operation of auxiliary circuits and control circuits for standard industrial environments, compatible with the AF09-AF96 contactor range. Side mounting CAL4 blocks are 2-pole with instantaneous N.O. + N.C. contacts, configured 1NO-1NC, and clip onto the right- and/or left-hand side of the contactor. The block is equipped with screw type connecting terminals delivered open, protected against accidental direct contact, and bears the corresponding function marking. Rated for use on auxiliary circuits at 50 Hz / 60 Hz.

Key Features

  • Configuration: 1NO-1NC (1 normally open, 1 normally closed) contact arrangement for auxiliary/control circuit switching.
  • Side Mounting: CAL4 2-pole block clips onto the right- and/or left-hand side of AF09-AF96 contactors for compact panel layouts.
  • Instantaneous Contacts: Instantaneous N.O. + N.C. contact action for reliable auxiliary signaling.
  • Connection Type: Screw type connecting terminals delivered open and protected against accidental direct contact.
  • Rated Frequency: Auxiliary circuit rated 50 Hz / 60 Hz for global voltage system compatibility.
  • Contactor Compatibility: Designed for use with the AF09-AF96 contactor and contactor relay range.

ABB CAL4-11 – Frequently Asked Questions

1) What contact arrangement does the ABB CAL4-11 give me?
One normally open and one normally closed contact, 1NO-1NC, with instantaneous action (no time delay). That covers the usual auxiliary jobs: a seal-in or run indication off the N.O. and an interlock or stop-permissive off the N.C. The suffix 11 in CAL4-11 is what designates the 1 N.O. plus 1 N.C. arrangement.
2) I use Square D gear, not ABB. Can I put a CAL4 block on a TeSys starter?
No. The CAL4 is a captive accessory for the ABB AF09-AF96 contactor family and will not clip to another manufacturer's contactor. On Square D platforms you match the block to the device family: the TeSys GV2/GV3 block for those manual starters, the TeSys Ultra block for Ultra overload relays, and the 8910DPA or Type S blocks for those contactor lines. Auxiliary blocks are not cross-brand interchangeable.
3) What is the Square D equivalent of the ABB CAL4-11 auxiliary contact block?
There is no drop-in Square D replacement, because the CAL4-11 is a side-mount block built specifically to clip onto the ABB AF09 through AF96 contactor range. The closest Square D counterparts are contactor-specific too: the Square D Type S auxiliary contact block and the 8910DPA series auxiliary contact block, each keyed to its own Square D starter family. If the panel already has an AF-series contactor in it, stay with the CAL4-11; if you are building new and want Square D throughout, pick the contact block that matches the Square D contactor you are specifying.
4) I need a 1 NO / 1 NC auxiliary contact but my starter is a Square D GV2 manual motor starter - can I use the ABB CAL4-11?
No. The CAL4-11 is a 1NO-1NC block that clips to the side of ABB AF09-AF96 contactors, and it will not engage a GV2 manual motor protector. For that starter, use the Square D TeSys GV2/GV3 auxiliary contact block, which is a 1 NO/NC front-mount block for the GV2 and GV3 range. Note the mounting difference as well: the GV2/GV3 block goes on the front face, while the ABB block occupies the left- or right-hand side of the contactor.
5) How do the terminals land on the ABB CAL4 auxiliary block, and do I need ferrules?
Screw type connecting terminals, delivered open so you can land conductors straight out of the box without backing every screw out first. The terminals are shielded against accidental direct contact and the block is function marked, so the contact numbering is readable in the panel after wiring. If your shop standard is spring clamp or push-in, this is not that block.
6) Can I mount two CAL4 blocks on one contactor, one on each side?
Yes. The CAL4 is designed to clip onto the right-hand and/or left-hand side of an AF09-AF96 contactor, so a pair gives you two extra N.O. and two extra N.C. contacts on a single contactor without adding a separate relay to the panel.
7) Will the ABB CAL4-11 work on a 60 Hz North American control circuit?
Yes. The auxiliary circuit rating covers both 50 Hz and 60 Hz, so it is at home on 60 Hz North American control power as well as 50 Hz systems. It is intended for auxiliary and control circuits in standard industrial environments, not for switching motor load current.
8) Front-mount or side-mount auxiliary contact block - which do I need for a tight MCC bucket?
It depends on which face of the device you have room on. The ABB CAL4-11 is a side-mount, 2-pole block that clips onto the right- and/or left-hand side of the contactor, so it adds width but leaves the front face clear for an overload or timer module. The Square D TeSys GV2/GV3 block is a front-mount 1 NO/NC unit, which preserves side-to-side spacing but builds depth ahead of the device. Measure the bucket in the direction you have the least clearance and pick accordingly.
9) What auxiliary contact block should I use on a TeSys Ultra overload relay instead of the ABB CAL4-11?
Use the Square D TeSys Ultra auxiliary contact block, which belongs to the TeSys Ultra series and is matched to that platform. The ABB CAL4-11 is dedicated to the AF09-AF96 contactor and contactor relay range and has no mechanical path onto a TeSys Ultra device.
10) Does the ABB CAL4-11 have a voltage rating I need to match, like the 120 VAC Square D block?
The CAL4-11 is rated for auxiliary circuit use at 50 Hz / 60 Hz, which covers both North American and international control voltage systems, so it is not tied to a single nameplate control voltage the way the Square D 8910DPA series block is listed at 120 VAC. Confirm your control circuit rating against the CAL4-11 spec sheet before finalizing the panel schedule.
11) How is an ABB CAL4-11 packaged, and is there a spec sheet for submittals?
It ships as a single piece, one each, so ordering quantity equals the number of blocks you get. ABB publishes a spec sheet for the CA4/CAL4 block, which is what most engineers attach to a control panel submittal package for the auxiliary contact detail.
12) Is the ABB CAL4-11 a screw-terminal block, or do I need to crimp ferrules like on some competing blocks?
The CAL4-11 uses screw type connecting terminals that are delivered open and protected against accidental direct contact, and the block carries function marking for each contact. That means you can land standard control wire directly without a special tool, though ferrules are still good practice on stranded conductors. Terminal style is worth confirming when cross-shopping the Square D Type S or 8910DPA blocks, since connection method drives how long the panel wire-up takes.
13) Can I order the CAL4-11 as a single piece for one contactor, or is it a multi-pack?
The CAL4-11 is sold as a single block, packaged 1 each, model CAL411. Each block gives you one normally open and one normally closed contact, so figure one per contactor per set of auxiliary contacts you need, and remember it can be clipped to either the left or right side if you are adding two.
