Square D Harmony Solid State Relay, DIN Rail Mount, 35A

Square D Harmony Solid State Relay, DIN Rail Mount, 35A

The Square D Harmony solid state relay is a DIN rail mounted power switching device built for industrial and commercial control panels. This relay mounts on 35mm symmetrical DIN rail conforming to IEC 60715 and secures with a locking mounting latch, delivering a 35A load current rating (0.15...35A) with an input control voltage of 4...32V DC and an output switching range of 48...600V AC. With zero voltage switching, pluggable spring input terminals, and compliance with UL 508 and CSA C22.2 No 14-13, this relay is engineered for reliable, code-compliant load switching in demanding automation environments.

Key Features

• Mounting: 35 mm symmetrical DIN rail conforming to IEC 60715, with a secure mounting latch for vibration-resistant installation.
• Load Rating: 35A power-rated relay with a load current range of 0.15...35A for demanding switching applications.
• Control Voltage: Input control voltage of 4...32V DC (Uc) for compatibility with common low-voltage control circuits.
• Output Voltage: Output switching voltage range of 48...600V AC for a broad span of load circuits.
• Zero Voltage Switching: Solid state output type with zero voltage switching to minimize inrush disturbance and electrical noise.
