Fits compact solid-state heater power control where you need a Watlow DIN-A-MITE A single-phase zero-cross SCR package up to 25 A at 600 VAC with DIN-rail mounting.
Key advantages
- Switching — Single-phase zero-cross up to 25 A at 600 VAC
- Mounting — DIN-rail and panel mount standard
- SCCR — 200 kA SCCR with proper fusing (tested to 480 VAC)
- Inputs — Variable time-base; 4–20 mA; VAC/VDC contactor versions
- Safety — Touch-safe terminals; mercury free; UL 508 / C-UL / CE / RoHS
Typical applications
- Heater power switching from temperature controllers.
- OEM panels needing compact SCR packages.
- Replacing mercury contactors with solid-state.
Selection guide
- Current / voltage — Load A and VAC
- Input type — VTB / 4–20 mA / contactor
- Fusing — Match SCCR documentation
- Cooling — Integrated heatsink ambient limits
Common mistakes
- Exceeding 25 A without stepping up to larger DIN-A-MITE.
- Wrong input type vs controller output.
- Skipping recommended semiconductor fusing.
When to RFQ / what to tell us
- Load V/A; input type.
- Ambient; fusing plan.
- Quantity and ship-to.
