SRH2/3 Series Three-phase Solid-state Relays (Integrated Heat Sink)
InquirySR2/3 series three-phase solid-state relays are available with separate heat sinks (SR2/3) or integrated heat sinks (SRH2/3). The relays control 2-phase or 3-phase loads and offer two mounting-hole patterns for compatibility with different heat sinks. Alarm outputs support safe operation, and 24VAC low-voltage models are available. Models with dielectric strength up to 4000VAC can be selected. Integrated heat-sink models support DIN-rail or panel mounting.
Main Features
Two mounting-hole types and sizes are available.
Alarm function (overtemperature detection).
- Alarm-output indicator (red LED), control cut-off output and alarm output.
High dielectric withstand voltage: 4,000 VAC (selected models).
Rated input voltage: 4–30 VDC, 24 VAC or 90–240 VAC.
Rated load voltage: 24–240 VAC or 48–480 VAC.
Rated load current: 15, 30, 40, 50 or 75 A.
A dedicated ceramic-board heat sink improves heat dissipation efficiency.
Supports zero-cross and random triggering.
Input indicator (green LED).
Multiple mounting options: DIN rail or panel mounting.
DIN-rail mounting is unavailable for 50 A and 75 A rated-load-current models.
