3-phase, zero cross SSR power controller

The Chromalox SSR family line of solid state relays are an ideal low cost power control solution for furnace/oven, heat treating, plastics, food, semiconductor, lighting, and drying applications just to name a few.

The SSR line of power controllers are a complete package. They feature a rugged design, touch safe exterior, back-to-back SCR design, ambient ratings of 40˚C, and are DIN rail mount.

The benefits from the Chromalox SSR line are quick and low cost installation, reduced panel space, increased heater life due to fast cycling, and easy replacements for mechanical contactors.

When using any of the SSR's to switch greater than 65 amps, 4 awg wire is required. Lug PN0013-40282 (PCN 389984) can accept a 4 awg wire and can be ordered.

SSR Series

These units are rated for 25, 50 and 75 amps with operational voltages up to 600 VAC. The series is zero-fired single phase control with 4.5 - 32 VDC and 24 - 265 VAC / 24 - 190 VDC control signals.

SSR1, SSR2 and SSR3 Series

These units are rated for 10, 15, 25, 35, 40, 50, 70 and 75 amps with operational voltages up to 600 VAC.

The series is zero-fired single phase, threephase two leg and three-phase three leg control. The control signal can be 4.5 - 32 VDC, or 24 - 265 VAC / 24 - 190 VDC.

SSR1P and SSR3P Series

These units are rated for 15, 25, 35, 40, 50 and 70 amps with operational voltages up to 600 VAC. The series is phase-angle fired single-phase and three-phase three leg design. The control signal can be 4 - 20 mA or 0 - 20 mA.
