RHS112A is a heatsink assembly designed for thermal management of solid state relays (SSRs), suitable for mounting up to 2 single-phase SSRs or 1 three-phase SSR. The heatsink features a thermal resistance of 0.76°C/W and is constructed from aluminum with black anodization finish, providing excellent heat dissipation performance. It supports both DIN rail and panel mounting with a maximum SSR mounting torque of 1.5 Nm, and includes thermal compound (HTS02S) for optimal thermal interface between the SSR and heatsink. The assembly weighs approximately 840 g (excluding SSR) and has dimensions of 112 x 103 x 80 mm, making it suitable for industrial control applications requiring reliable thermal management of power switching devices.
