Carlo Gavazzi RZ3A 3-Phase Panel Mount SSR
Dedicated 3-phase RZ3A modules sourced on request. For most 3-phase heater panels, three in-stock RM1A single-phase SSRs (one per phase) are a readily available alternative.
3-Phase SwitchingGenuine Carlo GavazziSourced on RequestTechnical Guidance
Our current stock covers Carlo Gavazzi's single-phase RM1A zero-cross range. The dedicated RZ3A 3-phase module is sourced on request against your exact part code. Many panel builders instead use three matched single-phase RM1A SSRs (one per phase, common-triggered) for 3-phase resistive heater loads - ask our team which approach suits your panel design.

Frequently Asked Questions
Can I use three RM1A units instead of one RZ3A?
Yes, this is a common practical approach for 3-phase resistive heater loads, provided each phase is switched consistently.
What is the lead time for RZ3A?
Typically 1-2 weeks, confirmed at enquiry based on stock availability from Carlo Gavazzi.
Do you provide wiring guidance for 3-phase SSR panels?
Yes, our technical team can advise on panel layout and control wiring.
