One-phase SSR – the key specs that decide fit
This SSD1A360BDC2 is a 60 A one-phase SSR from Schneider’s Harmony line. Zero-voltage switching keeps inrush low – ideal for resistive heater loads or lamp banks. Control voltage spans 4-32 V DC; the input draws 10-15 mA, so it plays nice with standard PLC transistor outputs. dv/dt is rated at 500 V/µs off-state – that’s the spec that keeps it from false-triggering on noisy mains or rail power. Response time is half a cycle on and off, fast enough for most cyclic processes.
Mounting and wiring – what takes up space on the rail
Width is 45 mm (one standard DIN unit), height 111.5 mm, but depth hits 154.4 mm – that’s the measurement to check against enclosure depth. Input terminals accept 0.08-3.3 mm² (AWG 28-12), output clamps take 10-26.67 mm² (AWG 8-3). Tightening torque is 0.5 N·m on control side, 2-2.2 N·m on the power clamps. No test button, but a green LED lights when control voltage is present.
Lifecycle and compliance – still active, fully certified
Lifecycle stage is current – no end-of-life notice. That means standard lead times and no forced last-time-buy. Compliance package includes UL 508, CSA C22.2 No 14-13, IEC 60947-4-3, IEC 62314, IEC 60950-1, and IEC 61373 Class B category 1 for rail vibration and shock. Dielectric strength is 4 kV AC between input/output and case.
