Carlo Gavazzi Launches New RGC3 Series Relays with Rated Voltage Up to 600 VAC

Press Release Summary:

The RGC3…48 Series Solid State Relays are offered with panel mount or universal, thru-wall mount or natural convection heatsink. The units come with rated current of 48 AAC at 40°C per phase with I2t rating of 15,000 A2s. The devices are suitable for applications such as HVAC, heat tracing, plastics or packaging. They feature an optional system monitoring with an electromechanical relay alarm and an auxiliary output. The relays have control voltages of 5-32 VDC or 20-275 VAC and SCCR of 100kA (when used with J-class fuse).

Original Press Release:

3-Phase SSRs for Panel Mounting 48 Amps Per Phase

November 27, 2018 - Buffalo Grove, IL – Carlo Gavazzi has launched the newest addition to its portfolio of 3-phase RGC3 Solid State Relays (SSRs). The RGC3.…48 Series, is a 48 AAC per phase rated device with a panel mount or thru-wall mount, natural convection heatsink.

The RGC3….48 Series of 3-phase SSRs have been very successful due to their recognition as one of the most compact 3-phase solutions on the market. To keep the dimensions compact, the existing RGC3 solutions at higher current ratings (above 40 AAC) utilize forced ventilation and hence require a supply voltage. The new 48 AAC rated 3-phase relay uses a larger, natural convection heat sink that eliminates the need for additional supply voltage if system monitoring is not required. The device can be panel-mounted inside of an electrical enclosure, or if a side-wall cutout is available, the heatsink portion of the relay can be mounted outside of the cabinet. Thru-wall mounting offers an additional benefit of keeping the heat generated during the operation of the SSRs outside of the enclosure, away from other sensitive electronic equipment.

The new 48 AAC rated RGC3….48 Series are available with line voltage ratings up to 600VAC, either DC or AC control, with optional system monitoring featuring electromechanical relay alarm and auxiliary output. Applications include HVAC, Heat Tracing, Plastics or Packaging, especially in situations where supply voltage is not available, or heat generated by the operation of an SSR has to be kept outside of the enclosure.

The specifications of the RGC3….48 Series include:

  • 3-phase, 3-pole switching solid state relays
  • Universal panel and thru-wall mount heatsink
  • Rated current: 48 AAC at 40°C per phase
  • Rated voltage: up to 600 VAC
  • Control voltage: 5-32VDC or 20-275 VAC
  • Optional system monitoring with alarms
  • Supply voltage only needed on system monitoring type
  • High I2t rating of 15,000 A2s
  • CE approved, cULus listed
  • 100kA SCCR if used with J-class fuse

The RGC3….48 Series SSRs are available from Carlo Gavazzi’s network of sales offices and distributors in the Americas, or at
