CG Solid State Relay SSR-60DD DC to DC Input 3-32VDC to Output
The SSR-60DD accepts a DC input and provides a DC output, rated for 60A with 50/60Hz capability. Size is approximately 58 x 45 x 32 mm and the weight is around 116 g. This model is suitable for DC-controlled loads such as DC motors or LED drivers where silent operation and fast switching are important. Best for DC-sensing control loops and compact installations. A limitation is that the device operates within specified input/output DC ranges; ensure your control signal matches 3–32VDC.
CG Solid State Relay SSR-60DA DC to AC Input 3-32VDC to Output 24-480VAC
This SSR-60DA converts a DC control signal to AC output, delivering 60A with a 24-480VAC output range. The same compact form as the 60DD version is offered, with thermal grease included for heat dissipation. Choose this when your control signal is DC but the load is AC. Caution: verify the AC load rating matches your circuit’s voltage and the load’s startup current.
YQSIYU 60A SSR AC to AC
The YQSIYU model is a 60A AC-to-AC SSR with dimensions around 62.6 x 45.3 x 23 mm and a lightweight build. It provides silent operation, thanks to solid-state switching, and is positioned as a compact solution for precise control in AC circuits. Best for space-limited installations; a potential limitation is that exact electrical compatibility with some high-inrush loads should be confirmed.
Baomain SSR-60DA 60A Solid State Relay Module 4-32VDC / 24-480VAC
The Baomain SSR-60DA module handles 4-32VDC input with 24-480VAC output at up to 60A. A heat sink option is listed, which is helpful for continuous operation or higher thermal loads. Best for applications needing higher ambient temperature tolerance and robust thermal management. Limitation: ensure your power wiring supports the 480VAC output range if used in higher voltage applications.
Shopcorp AC Contactor 60 Amp 75 RES 3 Pole 240V Coil
This 3-pole contactor is rated for 60 amps at 240V with a 220–240V coil. It’s UL-listed and tailored for HVAC, refrigeration, and heat-pump systems. Best for mechanical switching with strong arc suppression and robust contacts. Better for those who require a traditional contact closure rather than solid-state switching; note that mechanical wear is a consideration over long-term use compared with SSRs.
Buying Guide: Key Considerations For 60 Amp Relays And Contactor Systems
What load type are you switching? Solid-state relays excel for silent operation and fast switching with no mechanical wear, ideal for DC-to-AC or AC-to-AC control where EMI and switching noise must be minimized. Contactor switches are robust for high inrush loads such as HVAC equipment, motors, and refrigeration where physical isolation and high breakdown voltage are critical.
Control voltage compatibility matters. SSRs come with DC input options and AC or DC outputs; verify your control circuit matches the input requirements (e.g., 3–32VDC). For contactors, confirm coil voltage compatibility with your control system and whether a transformer or relay driver is needed.
Thermal management impacts reliability. Many 60A SSRs include heat dissipation features or require heat sinks. If your load runs hot or in a confined space, select a model with adequate heat-sinking or mounting provisions to prevent thermal throttling.
Voltage and current ratings must align with your load. Check the output voltage range (e.g., 24-480VAC) and ensure it matches the equipment you intend to switch. Also consider inrush current and surge ratings; motors and compressors may demand higher startup current than running current.
Warranty, certifications, and safety. Look for UL or equivalent listings for reliability and safety, particularly in HVAC or critical infrastructure. If the system is in a sensitive environment, ensure the device meets local electrical codes and installation practices.
FAQ: Quick Answers For 60 Amp 240V Relays
- What is the difference between SSRs and contactors? SSRs switch electronically with no moving parts and provide silent operation, while contactors are electromechanical devices that use a coil to close contacts. SSRs generally have longer lifespans in steady duty but may have leakage current. Contactors handle very high inrush loads well and are easier to replace in some industrial setups.
- Can a 60A SSR drive a 60A motor? Yes, if the SSR’s output voltage and current ratings meet the motor’s requirements and the inrush current is within the device’s specifications. Some motors have high startup surges; verify the SSR’s surge rating.
- Do SSRs need heat sinks? Many do, especially at 60A continuous load. Adequate cooling reduces thermal derating and extends life. Check the product’s thermal specifications and your mounting environment.
- Is a 240V coil compatible with standard control circuits? Coil voltage varies by product. Some coils are 220–240V; others use DC control signals (3–32VDC). Ensure the control logic matches the coil specification.
- Are these devices UL listed? Several items in this category are UL-listed or designed for HVAC and industrial applications. Always confirm current listings on the product page or datasheet before installing in critical systems.
- When should I choose a thermostat-contactor solution over an SSR? For frequent cycling, rough environments, or where mechanical isolation is required, a contactor is often preferable. For noiseless, rapid switching with longer life in clean signals, an SSR is typically better.
