Why Choose the GAX42040A?

The Lovato GAX42040A fourth pole add-on accessory upgrades GA016A–GA040A devices to four‑pole operation, with simultaneous closing operation as switch poles. Rated Ith 40 A and suitable for AC use, it supports AC21A, AC22A and AC23A duties. With 1000 V rated insulation (Ui) and 8 kV impulse withstand (Uimp), it delivers robust isolation in compact assemblies.

Engineered for reliability, this module offers 100000 mechanical and AC21A electrical cycles and IP20 frontal protection. It accepts 0.75–16 mm² conductors with 1.8 to 2 Nm terminal torque, operates from -25 to +55 °C, and suits altitudes up to 3000 m. Conforms to IEC/EN 60947-3/-1, UL508, UL98 and CSA C22.2 requirements.

Frequently Asked Questions

Is the GAX42040A compatible with my device?
It is an accessory for GA016A…GA040A versions. Check your device label to confirm the GA…A series.
What current ratings does this fourth pole support?
Ith is 40 A. AC21A and AC22A are 40 A at 400/500/690 V; AC23A is 40 A at 400 V and 25 A at 500/690 V.
Does the fourth pole close at the same time as the main poles?
Yes. It provides simultaneous closing operation as the switch poles for coordinated switching.
What are the installation requirements?
Use 0.75–16 mm² conductors and tighten terminals to 1.8–2 Nm. Always follow the manufacturer’s datasheet.
Which standards and environmental ratings does it meet?
It conforms to IEC/EN 60947-3/-1, UL508, UL98 and CSA C22.2, with IP20 frontal protection and pollution degree 3.

Safety note: Install and service only by qualified personnel. Isolate all power before work and observe specified ratings, wiring ranges and terminal torque.
