Square D GVAE1 – Frequently Asked Questions
1) Which Square D TeSys breakers does the GVAE1 auxiliary contact block fit?
The GVAE1 mounts on the front of GV2 and GV3 motor circuit breakers, specifically GV3L, GV2RT, GV2P, GV3P, GV2ME, GV2L and GV2LE. It is a front-mount block, so it occupies the face of the breaker rather than a side slot. If your protector is from a different family, this block will not seat.
2) Is the GVAE1 a normally open or normally closed contact?
Both, depending on how you mount it. The block gives one instantaneous auxiliary contact that acts as 1 NO or 1 NC based on the mounting orientation you choose on the breaker face. You order one part number, GVAE1, and decide the function at install.
3) Can I switch a 120V AC control relay coil with the GVAE1 contact block?
Yes, within its rating. The contact is rated up to 2A at 240V AC and 1A at 60V DC, with a rated operational voltage range of 24 to 240V AC and 24 to 60V DC. A 120V AC pilot relay or indicator lamp sits inside that. Anything drawing more than 2A needs an interposing relay.
4) I need an auxiliary contact for an ABB or Eaton manual motor protector, not Square D. What do I use?
The GVAE1 only fits Square D TeSys GV2/GV3 breakers. For ABB manual motor starters, the HK1-11 side-mount auxiliary contact suits MS116/132 protectors and gives 1NO/1NC. On the Eaton side, the XTPAXSA auxiliary contact is made for XT manual motor protectors. Auxiliary blocks are brand and family specific, so match the breaker, not just the contact arrangement.
5) I need an auxiliary contact rated for more than 2A at 240V - what should I look at instead of the GVAE1?
The Square D GVAE1 is rated 2A at 240V AC. If the signaling circuit needs a heavier rating, the Eaton C320DPG20 auxiliary contact kit is rated 10A at 600V with a 2NO configuration. Note that it is a kit for Eaton contactors rather than a TeSys GV accessory, so the host device has to match.
6) What is the closest equivalent to the Square D GVAE1 auxiliary contact if the panel uses Eaton manual motor protectors instead of TeSys GV breakers?
The Square D GVAE1 is a 1 NO/NC auxiliary contact block that mounts on the front of GV2 and GV3 motor circuit breakers, so it only fits the TeSys GV frames. For an Eaton manual motor protector, the comparable accessory is the Eaton XTPAXSA auxiliary contact from the XT series, which is built for manual motor protectors. Pick the accessory that matches the breaker brand and frame in the panel, because auxiliary blocks are not interchangeable between manufacturers' frames.
7) Is the ABB HK1-11 a drop-in substitute for the Square D GVAE1?
No. Both provide a 1NO/1NC auxiliary contact, but the ABB HK1-11 is a side-mount contact for ABB MS116 and MS132 manual motor starters, while the Square D GVAE1 installs on the front side of TeSys GV2 and GV3 motor circuit breakers. The mounting face and the host frame are different, so the two cannot be swapped on the same device.
8) Can I use the GVAE1 to add contacts to a disconnect switch or lighting contactor?
No. The Square D GVAE1 is built for TeSys GV2 and GV3 motor circuit breakers. For an ABB OT or OS disconnect, the matching accessory is the ABB OA1G10 1-NO auxiliary contact switch, and for an ABB 460 Line lighting contactor it is the CR460XB2 two-pole auxiliary contact block. Each of those is keyed to its own host device.
9) Does the GVAE1 auxiliary contact block meet UL 508 for a US control panel?
It is UL 508 listed and built to IEC 60947-1. Rated insulation voltage is 300V per CSA C22.2 No 14 and UL 508, and 250V per IEC 60947-1. That covers typical North American industrial control panel work as well as IEC-spec machine builds.
10) How do the terminals land and what torque should I use on the GVAE1?
Screw clamp terminals, tightened to 1.4 N.m. Bring your control conductors straight into the clamp, no ferrule-specific tooling or spring cage technique needed.
11) Can I add the GVAE1 to GV2 breakers already installed in a panel?
Yes, it is a field-addable block for GV2/GV3 retrofits. It clips onto the front face of the breaker, so you need clear depth ahead of the breaker in the enclosure and access to the front for the screw clamp terminals. Side-mount space is not required.
12) What is the difference between the Square D GVAE1 and the Eaton C320KG-SD auxiliary contact?
The Square D GVAE1 is a front-mounting block for TeSys GV2 and GV3 motor circuit breakers that gives one instantaneous NO or NC contact depending on how it is oriented, rated 2A at 240V. The Eaton C320KG-SD is a top-mount auxiliary contact for the Eaton Freedom series NEMA starters. One is an IEC-style breaker accessory, the other a NEMA starter accessory, and they mount on different faces of different devices.
13) If I need two normally open contacts rather than one, what are the options?
The Square D GVAE1 provides a single instantaneous contact that is either NO or NC depending on mounting orientation. For two NO contacts in one accessory, the Eaton C320DPG20 kit is a 2NO auxiliary contact and the Eaton ARA20 top deck adder for AR/ARD machine tool relays is also a 2NO configuration. Both are Eaton-frame accessories, so they suit Eaton devices rather than a TeSys GV breaker.
14) Does the ABB CR305X auxiliary contact work with TeSys GV2 breakers?
No. The ABB CR305X series auxiliary contact is intended for ABB contactors and relays, while the Square D GVAE1 is a front-mount block for TeSys GV2 and GV3 motor circuit breakers carrying the GVAE compatibility code. If the panel has a TeSys GV protector, stay with the GVAE accessory; the CR305X belongs on the ABB contactor line.
15) Will the GVAE1 hold up to frequent operation on a machine that cycles all day?
The block is rated for 100,000 mechanical operating cycles. That is a signaling contact for breaker status, not a load-switching device, so keep it on pilot duty within the 2A/240V AC rating and the mechanical life is the limiting factor rather than the contact.
