Celduc Relais Solid State Relays SIT867570

The SIT867570 is a three-phase zero-cross solid state contactor designed for resistive loads, operating from 24 to 520 VAC with a nominal current of 3 × 22 A RMS under AC-51 conditions. It features a DC control voltage range of 10-30 VDC with a green LED indicator, and includes an integrated heatsink for DIN rail mounting with IP20 protection. The device uses high-efficiency back-to-back thyristors with TMS technology, offering an I²t rating of up to 7200 A²s and a maximum on-state voltage drop of 0.9 V. It provides reinforced insulation with 4000 V RMS input-to-output isolation and meets EN60947-4-3, EN60950/VDE0805, UL, and cUL standards. Operating temperature ranges from -40 to +100 °C, with a weight of 1000 g.
