CELDUC SU963460 Celpac SU9 Single-phase Zero-cross Solid State Relay (SSR)

Overview The CELDUC SU963460 belongs to the Celpac SU9 2G series single-phase solid state relay, designed for resistive AC-1 loads. It adopts zero-cross switching technology to reduce EMC interference, widely stocked as spare for heating control, oven, packaging and industrial temperature control cabinets.

Features This SSR is rated 35A, 24–600VAC output, with 3.5–32VDC DC control input. The SU963460 has built-in status LED indicator, low-profile 22.5mm width housing, panel mounting design, IP20 protective cover and screw power terminals. It uses TMS² thermal management technology to extend service life and suppress inrush current for resistive heating loads.

Specs Model: SU963460 Series: Celduc Celpac SU9 Type: Zero-cross solid state relay Load voltage: 24–600VAC Load current: 35A (AC-1) Control input: 3.5–32VDC Switching mode: Zero-cross Mounting: Panel mount Protection class: IP20 Certifications: CE, UL, cUL Product status: active industrial spare

Principle Back-to-back thyristors perform AC switching at the zero-cross point of the sine wave. The control circuit receives DC trigger signal to turn on/off the power loop, avoiding arc and noise generated by mechanical contacts.

Applications The SU963460 is widely deployed in electric heating furnaces, packaging machines, plastic extrusion lines and HVAC heater control panels. It is used for frequent on-off control of resistive heating loads.
